RADIANT CUT DIAMONDS, THE MOST UNDERRATED DIAMOND SHAPE

%Jeweler NYC %NYC Wholesale Diamonds

Radiant cut diamonds possess a silhouette shape very similar to an emerald shape, but its facets are cut in a more similar way to that of round diamonds. This means that the appearance of the diamond has an effervescent sparkle, hypnotizing those who catch its gaze.
Radiant Cut Diamonds are also currently 20% less in price than round diamonds. This is a temporary anomoly that provides opportunity as historically the price spread is 2 to 3%.
Why are Radiants not more mainstream and known?
I was blessed to know the late creator of the Radiant Cut, Henry Grossbard and remain friends with his son Stan. Henry did not invent this magnificent cut until 1981. This recent discovery might help explain it is still somewhat unknown to many. Here is Henry’s story:
Henry Grossbard invented the Original Radiant Cut Diamond. Early in his life, one pivotal moment changed everything: a friendly American Consulate clerk expedited Henry’s family’s application for an emigration visa, freeing them from a Nazi camp in occupied France. Once in America, Henry spent his life learning the diamond trade. He perfected his skills for over 30 years. Then he changed the diamond industry forever.
“An experienced craftsman can look into a rough stone and see the finished diamond,” was Henry’s motto. Henry knew that many people loved the elegant rectangular shape of an emerald cut diamond but felt it just didn’t sparkle enough. After lots of careful, expensive experimentation, Henry perfected the Radiant Cut in 1981. This break-through revolutionized the industry, infusing the classically elegant emerald cut shape with unparalleled scintillation.

Every Piece Of Jewelry Prince William Has Gifted To Kate Middleton

%Jeweler NYC %NYC Wholesale Diamonds

 

Marrying into the royal family comes with many perks, including easy access to private jets and VIP admission to some of England’s grandest estates. However, one of the most remarkable privileges royal women enjoy is access to a seemingly endless amount of historic jewels. As the future Queen of England, Catherine, Princess of Wales, has a beyond luxurious collection of multi-carat jewelry pieces. From diamonds dating back to the nineteenth century to rare gemstones, Princess Catherine’s public appearances are almost always sparkling occasions.
However, as robust as the princess’ jewelry collection may be, some pieces must be more sentimental than others. Eagle-eyed royal watchers have noticed that many of Princess Catherine’s jewels seem to be gifts from her husband, William, Prince of Wales. Between birthdays, anniversaries, and the joyous births of their three children, doting father and husband William has had many opportunities to shower his wife with shimmering gifts.
Dating back all the way to the early days of their courtship, it seems diamond necklaces, rings, and earrings have routinely been William’s go-to way of showing love and appreciation to his beloved Catherine. While many of the jewels and gemstones William has gifted to Catherine are personally commissioned pieces, others are royal heirlooms that the prince has passed on to his wife. Considering such glistening gifts appear again and again throughout the royal couple’s relationship timeline, let’s take a trip down memory lane and revisit every illustrious piece of jewelry the Prince of Wales has gifted his princess.
One of the first pieces of jewelry Catherine, Princess of Wales, ever received from her future husband was a dreamy diamond eternity ring, a traditionally romantic gift that is said to represent lifelong love and loyalty. The public got their first glimpse of this showstopping piece of jewelry at the future Prince and Princess of Wales’ graduation from the University of St. Andrews in Scotland, where the lovebirds first met as fellow Art History students.
The paparazzi snapped away as a young Catherine made her way to the 2005 ceremony, having accessorized her customary black graduation gown with her newly gifted eternity ring. Despite the commotion happening on the St. Andrews streets that summer’s day, it was the glint of Catherine’s ring that captured the eagle-eyed media’s attention. Spectators were quick to notice that the ring featured intertwined bands of garnets and pearls — the birthstones of Catherine and William, respectively.
Though it would be over five years until the college sweethearts would say “I do,” the prince’s genuine romantic feelings for Catherine were clear for all to see. This proto-engagement ring not only represented William’s intentions for their combined future, but it also surely cost a pretty penny, being made of pure rose gold. Catherine showed her appreciation for the gift by wearing it frequently during the early days of her and Will’s courtship, including such events as Laura Parker-Bowles’ 2006 wedding and Wimbledon 2006.
In the autumn of 2010, after nine years of dating, Prince William finally popped the question to his longtime sweetheart. While the proposal itself happened while the two were on a private vacation to Kenya, the world first heard the news — and got a glimpse of Princess Catherine’s dazzling engagement ring — during an interview and photocall on November 16, 2010. From that moment on, the world couldn’t take their eyes off Catherine’s unique engagement ring.
The piece features a whopping 12-carat Ceylon sapphire in an oval shape, surrounded by a cluster of 14 diamonds and set in a band of 18-karat pure white gold. Not only is this sapphire stunner one of the most important pieces of jewelry William has ever gifted his wife, but it is also one of the most iconic rings in royal history. As fans of “The Crown” will know, the ring was originally gifted to William’s mother, Princess Diana of Wales, when she first married Prince Charles. However, it dates back much further than their ill-fated 1981 nuptials.
In actuality, the ring found its beginning with a much happier union, having been commissioned by Prince Albert as a gift for his then-fiancé Queen Victoria. Originally crafted as a sapphire and diamond encrusted brooch, the piece was worn by Queen Victoria on her 1840 wedding day. The monarch continued to wear the brooch throughout her 63 year reign and only retired it when her “dearest Albert” passed away in 1861.
Per tradition, Prince William gifted Catherine, Princess of Wales, a wedding band to accompany her engagement ring during their April 25, 2011, wedding ceremony. Dating all the way back to Ancient Egypt, wedding bands are traditionally meant to be worn on the fourth finger of your left hand, where the vein is said to travel directly to the heart. While engagement rings are usually more flashy, a wedding band, gifted on the actual day of the wedding, is meant to be simpler in design.
As high-profile members of the British royal family, it’s no surprise that William and Catherine’s ring exchange fit perfectly into this classic, understated mold. While Catherine’s sapphire engagement ring added a bit of unexpected flair to her royal jewelry box, her classic gold wedding band harkens back to time-honored wedding customs. Made from 100% pure Welsh gold, this piece of jewelry was also a royal family heirloom.
As noted in a statement from Clarence House provided to World Gold Council ahead of the couple’s wedding, the gold that was used to make the ring was sourced from one of the royal family’s gold mines in Wales and was a gift from the queen herself, given to Prince William only a few weeks after the young couple announced their engagement. With this ring, Catherine joins a long line of women in the British royal family to wear wedding bands made of Welsh gold, starting with the Queen Mother in 1923.
Princess Catherine’s post-engagement earrings
These unique pieces made their debut when Catherine and William embarked on a tour of North America shortly after their wedding in 2011. During this inaugural trip as the Duchess of Cambridge, Catherine frequently wore two of the most poignant jewelry pieces William has ever gifted to his wife: these dainty, single-drop sapphire earrings. While neither Catherine nor William have spoken publicly about these pieces, it is believed that they were gifted to Catherine in 2010 not long after their engagement.
The post-engagement theory is backed by the fact that these sensational sapphires appeared on Catherine’s lobes most frequently in the years immediately following her wedding, not to mention the fact that they perfectly match her engagement ring. In addition to trotting across the U.S. and Canada in these sparkling sapphires, the then-Duchess of Cambridge was also spotted wearing William’s sapphire earrings to royal engagements in Scotland, New Zealand, and even at Prince Philip’s 90th birthday service.
Like her engagement ring, Catherine’s earrings also once belonged to William’s late mother, Princess Diana of Wales. However, rather than being a romantic gift from Prince Charles, Diana received these earrings as a gift from Crown Prince Fahd of Saudi Arabia to congratulate the new princess on her wedding. Coming directly from her fiancé, however, William and Catherine have clearly put their own personal twist on these rare jewelry pieces. Additionally, the fashion-forward Catherine also modified the sapphire studs by having them redesigned into a high-hanging drop style.
For her first Christmas as an official member of the royal family, Catherine, Princess of Wales, turned out in a beautiful garnet-hued look. Along with her funnel-necked coat dress and matching hat and clutch, the newlywed also stepped out in a pair of new diamond earrings that had never before been seen by the public. While nothing has been officially confirmed, many believe that these were a Christmas gift from Prince William to his new bride in 2011.
Designed by luxury British jeweler Kiki McDonough, Catherine’s earrings consist of a round green amethyst looped by small diamonds and set in 18-carat gold. Like many earring designs worn by Catherine before, these Christmas-inspired pieces also feature a slight drop design, dangling gracefully from the royal’s ears. Throughout the Christmas day’s goings-on, Catherine was seen engaging with the public as she left St. Mary Magdalene Church and walked around the royal estate of Sandringham in Norfolk, speaking with excited young fans, and accepting endless bouquets of flowers.
As a young, fresh face on the royal scene, Catherine’s first Christmas with the British royal family was an important opportunity for the newly inducted Duchess of Cambridge to crystallize her reputation as a sophisticated dresser. With the help of Prince William and his refined taste in jewelry, it seems the young wife succeeded. Just as Kiki McDonough also regularly designed jewelry for Princess Diana, Catherine’s modern style and her popularity with the British public mimics that of her late mother-in-law.
As the future Queen of England, Princess Catherine is one of the most high-profile women in the world and, like any good blue blood, she too owns a Cartier watch. It seems the French jewelry company is the go-to choice for the most elegant of elites, as a litany of royal women and even former U.S. First Lady Michelle Obama have been spotted wearing Cartier brooches, necklaces, and watches throughout the years.
What makes Catherine’s Cartier piece extra personal, however, is that it is believed to be a gift from her husband, William, Prince of Wales. Catherine’s watch is so special that it even has its own name — the Ballon Bleu de Cartier. The timepiece is named for its unique blue hands and attached sapphire stone, which perfectly match the princess’s other cerulean-hued pieces. Echoing Catherine’s famous engagement ring and matching earrings, these sapphire features suggest the Ballon Bleu is, once again, the work of jewelry-lover Prince William.
While Catherine’s style is usually of the regal variety and never too flamboyant or flashy, the Ballon Bleu adds an exciting spark to her usual fashion fare. You can often spot the stainless steel case and bracelet glinting in the sun during the princess’s royal engagements, reminding those around her that they are in fact speaking to a woman who owns not one, but multiple, real life tiaras. To make this gift even sweeter, it appears that William owns a matching masculine version — the Omega Seamaster 300M.
Princess Catherine’s first push present
While men have been gifting their wives engagement rings and birthday diamonds for hundreds of years, a new ceremonial gift called a “push present” has recently taken the world by storm. This gift is meant to be given to a new mother by the father of her child to mark the life-changing experience of bringing life into the world. Evidence shows that push presents are becoming increasingly popular throughout the U.K. and the U.S., with Crisscut Magazine reporting searches for the phrase “push gift jewelry” were up by 50% in early 2022.
It seems the Prince and Princess of Wales are no exemption, as royal insiders have claimed that Princess Catherine received multiple push presents to mark the birth of her first child, Prince George of Wales, in 2013. The sweetest of these gifts was a unique teddy bear reportedly purchased from the luxury department store Harrods, while the splashiest gift was a new diamond-encrusted eternity band. Mimicking the eternity ring that Prince William gifted his wife way back in their college days, this personal push present must hold extra sentimental value for the couple.
While Princess Catherine famously debuted her first eternity band at her college graduation, spectators noticed that her postpartum looks almost always included this beautiful piece known as the Eclipse Diamond Eternity Ring. The classic piece contains a band of 18-carat white gold and is looped by 0.23-carat white diamonds, boasting a level of bling that surely captures the attention of anyone in its vicinity.
One of the more mysterious items of gifted jewelry that Princess Catherine is said to own is a pink diamond brooch, reportedly given to her by Prince William as one of the multiple push presents he gifted to the new mother in 2013. This interesting piece has yet to be spotted out in public, but U.K. tabloids report that the prince took the creation of the brooch seriously and even went as far as to employ the help of Queen Elizabeth II’s personal jewelers.
William’s choice of such a feminine piece could be explained by the fact that he and his wife have routinely opted to keep the gender of their children a surprise until the birth, as per royal tradition. As any nervous father shopping for his wife’s first push present, one can imagine that the Prince of Wales commissioned the pink diamond brooch and the diamond eternity band to cover all his bases — one gift for the birth of a son and one for a daughter.
However, another theory could be that the royal family simply has a penchant for pink diamonds. William’s late grandmother was frequently spotted at royal engagements, including her Silver Jubilee, wearing a jaw-dropping 54.5-carat pink diamond brooch cut into a floral shape. While there are no rumors of Princess Catherine’s mysterious pink brooch reaching the queen’s level of splendor, it’s a sweet thought to imagine the future Queen of England following in her predecessor’s fashion footsteps.
For the birth of the couple’s second child, Princess Charlotte of Wales, on May 2, 2015, Prince William switched up his gift giving tactics. Instead of opting for a diamond ring or a multi-carat brooch, Prince William gave his wife a gorgeous pair of amethyst and tourmaline earrings. While Catherine debuted these jewels on the couple’s royal tour of India and Bhutan in 2016, the designer, Kiki McDonough told People that the earrings were commissioned by Prince William the year prior to celebrate his daughter’s birth.
It seems Prince William is a savvy observer of his wife’s taste in jewelry, as Catherine has been seen wearing other Kiki McDonough designs throughout the years, including her first Christmas with the royal family at Sandringham and an official trip to New York in 2014. However, these particular pieces are decidedly more colorful than your average pair of royal earrings, consisting of yellow amethysts that hang in teardrop formation from a pair of bright green tourmalines. However, the earrings retain a classic feel by being circled in a series of diamonds. To top it all off, the entire set is placed in 18-carat yellow gold.
The pop of color offered by the earrings aligned perfectly with the spring season in which Princess Charlotte came into the world, and Princess Catherine has repeatedly chosen to pair the Kiki McDonough pieces with similarly brightly-hued gowns. In New Delhi, India, for example, Catherine debuted the pieces alongside a beautiful turquoise gown.
2012 was a big year for the U.K., considering that the Summer Olympics were hosted in London that year. Given that Catherine, Princess of Wales, is one of the most prominent members of the monarchy, it’s no surprise that the princess decided to match her 2012 fashion looks with the Olympic theme. In July of that year, Catherine caught the eye of royal fans by visiting the National Gallery wearing a three-ringed piece known as the Cartier Trinity Necklace.
The choice of necklace was incredibly on point for the occasion, as Catherine was attending the unveiling of the “Road to 2012: Aiming High” exhibition, which included 100 new portraits of famed British athletes and athletic events. However, while the average spectator may assume that Catherine’s Cartier Trinity Necklace was cultivated specifically for the National Gallery exhibit, royal insiders have hinted that the piece was gifted to Princess Catherine by her husband to mark the royal’s 30th birthday.
In fact, the necklace is much more expensive than royal watchers have come to expect of the relatively frugal Princess of Wales, as the Trinity Necklace has been estimated to cost around £50,000. It’s no surprise that the Cartier piece bears an eyebrow-raising price tag, as the 18-carat chain is dotted with pavé diamonds and features three interlaced rings of yellow, pink, and white gold. With a price tag this high, it only makes sense that this luxury necklace was a gift bought by someone looking to impress the princess.
Making its debut just a mere two weeks before Princess Catherine’s 38th birthday, it is rumored that this gorgeous gold necklace — known as the Gold Midnight Moon necklace – was a birthday present from Prince William to his wife. The royal stepped out wearing the piece for the first time at the Ely and Caerau Children’s Centre in Cardiff, Wales in January of 2020 as part of her royal initiative to introduce a new national survey on early childhood development.
It was a stellar style choice to choose to debut the necklace at a Children’s Centre, as an up-close look at the necklace reveals that it includes the initials of Catherine’s three children: Prince George, Princess Charlotte, and little Prince Louis. While no one from the royal family has directly confirmed that this necklace was a gift from William to Catherine, gifting the mother of his children a piece that commemorates the three Wales youngsters sounds exactly like the kind of sentimental, yet elegant, move that a savvy gift-giver like William would make.
An un-personalized version of the Gold Midnight Moon necklace is also available to purchase directly from England-based designer Daniella Draper’s website. The dainty diamond-encrusted piece is also indicative of William and Catherine’s passion for green living, as the piece is completely constructed out of recycled material. With a circular base and chain made from 9-carat yellow gold, there are also three minuscule diamonds embedded into the necklace’s gold disk base.
While these iconic pearl drop earrings were originally gifted to Princess Diana by Collingwood jewelers in 1981, the fact that Princess Catherine has been spotted out and about rocking these classy pieces at multiple occasions has led royal insiders to believe that Prince William has since officially passed these earrings down to his wife. The late Princess of Wales wore a lot of beautiful jewelry in her lifetime, but these earrings seemed to be a favorite of the royal, as she famously wore them throughout her 1985 tour of America.
Perhaps most iconic of all, these earrings were also seen hanging from Princess Diana’s ears on the night of June 29, 1994 — the same night she wore her “revenge dress” to London’s Serpentine Gallery. The dress became known as the “revenge dress” due to its debut coinciding with the premiere of a televised interview where Prince Charles admitted to an extramarital affair with Camilla Parker Bowles.
Princess Catherine’s adoption of the Collingwood pearl earrings will ensure that these unforgettable pieces will remain in the spotlight for years to come. Just as they added an extra spark to her late mother-in-law’s looks, Catherine has already opted to wear the pearls at multiple occasions, including Queen Elizabeth II’s 2022 funeral procession and a 2022 Remembrance Sunday Service. These lovely pieces are easily identifiable by their unique bell cap design, from which two chunky pearls hang. At the base of the ear, of course, sit two sparkling diamond studs.
Princess Catherine’s push presents for her first two children — Prince George and Princess Charlotte — are known to the public, but it’s been a bit of a mystery what Prince William decided to gift his wife for the birth of their third child, Prince Louis. However, considering the royal splashed out in a big way for the birth of the two eldest Wales children, we can assume that Catherine’s third push present carried an equally impressive price tag.
As Hello! has noted, one piece of jewelry that many have speculated is the ever-evasive third push present is a beautiful citrine ring Catherine was spotted wearing several times throughout 2018. The public got a look at the ring during Wimbledon that year, only a few months after Prince Louis arrived. On the final day of Wimbledon, Catherine stepped out with husband Prince William to attend the Men’s final match between Novak Djokovic and Kevin Anderson. For the exciting occasion, the princess decided to pair her eye-catching yellow ring with a similarly bright buttercup-colored dress.
The hefty ring looks incredibly similar to a ring Catherine was also spotted wearing in the early 2000s, but the push present theory is backed up by the fact that this specific citrine ring really began catching the public’s eye the summer following Prince Louis’ birth. Even if this citrine jewel wasn’t bought to commemorate little Louis’ entrance into the world, it’s still possible that William was behind the purchase of this significant piece.
Passing down another iconic piece from his mother’s collection, Prince William is also believed to have given his wife his blessing to sport Princess Diana’s beautiful three-strand pearl bracelet. Considering Catherine, Princess of Wales, is usually seen out and about wearing jeweled earrings, rings, and even some impressive necklaces, this vintage pearl bracelet represents a departure from her usual fashion choices.
It seems that Catherine pulled this rogue piece from her jewelry box for a special reason — to follow the royal tradition of wearing pearls during a period of mourning. After Queen Elizabeth II’s death on September 8, 2022, the newly-inaugurated Princess of Wales was seen regularly wearing black ensembles and pear-accented jewelry to various royal engagements. Most notably, Catherine sported her late mother-in-law’s bracelet to a meeting with Ukraine’s First Lady Olena Zelenska to discuss the issues facing her country following the Russian invasion.
The bracelet itself was designed back in Diana’s day by Nigel Milne, who was deeply attuned to the late princess’s charitable interests. After working with Princess Diana on the crafting of the three-strand bracelet, Milne and his wife Cherry even went so far as to create a line of jewelry whose proceeds went directly to “BIRTHRIGHT,” a charity foundation that claimed Princess Diana as one of their patrons. By donning this piece at her more solemn royal engagements, Catherine seems to be channeling a bit of her late mother-in-law’s charitable and graceful spirit in addition to Diana’s impeccable fashion sense.
One of Princess Catherine’s more bold fashion choices was this bright, lime green gown she chose to wear for the 2022 Earthshot Prize ceremony. Coinciding with the royals’ trip across the Atlantic, this year’s prize ceremony was hosted in Boston, Massachusetts. The princess’ off-the-shoulder, long-sleeved column dress was the perfect choice for the Earthshot ceremony, as Catherine and her husband Prince William confidently posed on the unique green carpet outside of Boston’s MGM Music Hall.
Launched by the Prince of Wales in 2021, the Earthshot Prize has one purpose and one purpose only — to encourage better care of our earth and award those who are making significant strides in saving the environment. By choosing an overall emerald-hued look for the occasion, Catherine subtly showed her support for her husband’s environmental activism.
In addition to her vivid, chic dress, Catherine completed her look with a heavily jeweled emerald-and-diamond choker that once belonged to her late mother-in-law, Diana, Princess of Wales. Considering Prince William inherited much of his mother’s jewelry after her passing, we can surmise that this piece of jewelry was also a sentimental gift passing from husband to wife. Diana famously wore the choker as a headband during a royal engagement in 1985, but the piece originally made its debut back in 1911 when it was gifted to Queen Mary during the Delhi Durbar.
Our sincere thanks to The List and Elizabeth Williams for this very detailed and fascinating information

Why are Pink Diamonds Pink?

%Jeweler NYC %NYC Wholesale Diamonds

 

GIA Researchers Dive Deep into their Crystal Structure
Natural pink diamonds are among the most valuable and rare of Earth’s treasures. Top, vivid-colored stones can bring more than $2 million per carat at major auctions. Such prices come from their rarity as much as their beauty – only a tiny percentage of diamonds have pink color, and only a tiny percentage of these have a rich, vivid color.
Pink diamonds created in a laboratory, however, are quite different from most of their natural counterparts. Manufacturers can’t replicate the way the vast majority of these fancy colored diamonds formed in nature, according to GIA researchers.
Employing GIA’s immense database of more than 90,000 natural pink and related colored diamonds graded between 2008 and 2016, GIA researchers Dr. Sally Eaton-Magaña, senior research scientist; Troy Ardon, research associate; Dr. Karen V. Smit, research scientist; Dr. Christopher M. Breeding, senior research scientist and Dr. James Shigley, distinguished research fellow, produced the most detailed and comprehensive gemological analysis of pink diamonds to date, published in the Winter 2018 edition of the Institute’s quarterly journal, Gems & Gemology.
The sample set of 90,000-plus diamonds includes all those submitted to GIA from 2008 to 2016 with pink as a primary color, and also spans the color hue range from red to purple and saturation range from faint to dark, along with brown diamonds, which share a similar cause of color as pink and related stones. Many of those 90,000 diamonds were small, with low color saturation.
This research confirms that the color of 99.5% of pink diamonds comes from distortion in their crystal structure, not from trace elements, such as nitrogen, which causes yellow color in diamonds or boron, which causes blue. In pink diamonds containing nitrogen, the color is generally concentrated within parallel narrow bands called glide planes, lamellae, or pink/brown graining, depending upon the color. These lines are visible under a microscope and cutters orient them perpendicular to the table to maximize body color.
While many color-producing defects can be introduced through laboratory treatment processes, atomic level distortions in a diamond’s crystal structure created by plastic deformation cannot.
“We know that plastic deformation is associated with the vast majority of diamonds with these colors, but we still do not know the actual atomic structure of the defect causing the color,” says Breeding, who notes that the pink color is caused by a broad absorption band centered at 550 nanometer (nm) in spectroscopic analysis. Spectroscopic analysis is an important gemological tool to measure the impurities and other defects within a diamond (and other gemstones) that give rise to specific absorption peaks or bands in the visible spectrum. The researchers said that there is no known method of replicating plastic deformation with the 550 nm absorption band by a laboratory treatment or growth process.
All fancy colored diamonds submitted to GIA’s grading laboratories are subjected to rigorous analysis to be certain that the colors ‒ and the diamonds themselves ‒ are of natural origin, which makes the GIA database extensively detailed and valuable for research, Shigley said. He added that the team selected a representative sample of 1,000 pink diamonds to examine even more thoroughly for the Gems & Gemology article.
Size and Color Statistics: Are Pink Diamonds Rare?
Of the group of diamonds in this study 47% were unmodified (no other color observed) pink; 28% were purplish pink to pinkish purple; 17% were brownish pink to pinkish brown; 10% were brownish orangy-pink to orangy-pink; 3% were brown; 1% were purple-brown, purple-gray and purple; and 0.9% were red, brown-red or orange red. Of the unmodified pink diamonds, 54% were graded faint to light pink.
While brown diamonds are among the most common fancy colors in nature, the low percentage of them in this group suggests that most are sold into the market without grading reports. The brown color is accompanied by other hues, such as pink or yellow, or the brown stones are treated to produce other colors.
The vast majority of the group (83%), weighed less than one carat, with 56% of them being under one-half carat. The dominant shapes were round (24%), pear (20%), rectangle (16%) and cushion (13%).
The research ‒ the most extensive ever carried out on pink and associated colored diamonds ‒ found that 25% are type IIa, which is much higher than with colorless to near-colorless diamonds (where the percentage is < 5%), Breeding said.
The majority of type Ia pink diamonds (diamond containing clusters or aggregates of nitrogen atoms as impurities in the crystal lattice) almost exclusively come from two sources: Australia’s Argyle mine and Russia, which also happen to be the most prolific and consistent producers of such stones. Type IIa pink and other type Ia pink diamonds come from other sources – such as Tanzania, South Africa, and Brazil – but there is no reported regular production from any mine.
“It’s unusual that these types are from very specific locales, especially because they are so rarely found in other sources,” Breeding noted, adding that because Argyle is the dominant source for highly saturated (colored) pink, purplish-pink and red diamonds; the decline in the numbers of such stones will be substantial after the mine closes next year.
Research Aids Automated Detection of Treatment/Lab Growns
This pink diamond study enables GIA to better understand how these rare and beautiful diamonds formed and the properties that give them their color. The researchers found many new details at the atomic level by analyzing the absorption spectroscopy and photoluminescence data. These findings add to the understanding of these amazing stones – which can enable faster, more accurate identification.
The research from this study reinforces GIA’s development of an upgrade for the GIA iD100® gem testing device that adds a function to accurately screen pink and related color diamonds for treatments and synthetics.

Diamonds: A Girl’s Best Friend And Now A Unique Investment Opportunity For Women

%Jeweler NYC %NYC Wholesale Diamonds

 

Elizabeth Taylor once said, “Big girls need big diamonds.”
Dana Auslander agrees. The veteran hedge fund executive is shaking up the investment world, creating a unique new asset class that sits at the intersection of finance and luxury, and gives all women the opportunity to actually own diamonds. Big diamonds.
Launched last year, the all-women founded LUXUS is the first SEC-qualified alternative investment platform that allows any investor to purchase luxury jewels – previously only accessible by the uber wealthy – through fractional ownership.
Making Luxury Accessible to Everyone
Simply put, rather than owning shares of a publicly traded company, LUXUS enables the ordinary investor to now own shares of a publicly traded diamond. Like a rare, 5 carat, D-Flawless Kwiat diamond, for example. Here’s how.
Auslander’s team identifies macro trends (like colored diamonds) in the high-end gem space and partners with brands who may have a valuable gem in inventory or who may be able to procure one directly from a mining company. LUXUS prices the gem and securitizes it, creating a financial instrument that can be split up and sold to investors. The company files with the SEC and “IPOs” the gem, much like a company would IPO. The total value of the gem is divided into shares, which can be purchased by any investor.
For example, the diamond mentioned above is valued at $400,000, but is being offered to the public in the form of 1,600 shares at $250 each. Shares will ultimately be tradable in a secondary market and after a few years the diamond will sell back to the private market – a built-in private equity exit on the back end.
An Attractive New Asset Class
Owning fractional shares of diamonds can be an appealing alternative investment option for the mainstream investor. First, unlike cryptocurrency and NFTs – which SEC Chairman Gary Gensler has described as the “Wild West” and “lacking proper regulatory compliance” – investing in securitized gems is highly regulated. The platform is governed by FINRA and the SEC and all assets have certificates from the Gemological Institute of America and the International Gemological Institute, attesting to quality and valuation.
Second, precious metals, like gold and silver, have long been used as hedges in times of inflation and market volatility. And now diamonds are performing the same role. “Over the past 3 years, large, investment grade diamonds of flawless clarity have significantly outperformed the SPX (the S&P 500 Index) and gold, demonstrating their value as an inflation hedge,” Auslander shared last month during the launch of the company’s third IPO.
And finally … bragging rights! “I want people to be able to say, ‘I own this Tutti Frutti by Cartier from the 1930s or I own this pink diamond from the Argyle Diamond Mine,’” Auslander said. Interestingly, the Argyle Diamond Mine is closed and there will be no more pink diamonds mined from the earth- ever again. Scarcity like this makes owning rare gems, even fractional shares, that much more valuable and desirable.
Capital Markets as a New Sales Channel
Luxury jewelry brands are eager to participate in the securitization and fractional sale of their gems for several reasons. First, it provides a low-risk way for the brands to be perceived as innovative and “tech forward.” Many attempted a foray into the world of NFTs with less than stellar outcomes.
It also allows jewelry brands to reach a much larger audience – effectively using the capital markets as a new sales channel. This is particularly appealing to brands who have been struggling to compete against the larger conglomerates, like Sotheby’s and Christie’s, and to those brands who have felt the sting of the significant decline in Asian tourism. Chinese consumers purchase about one-third of the world’s luxury goods. And while in 2019 almost three million Chinese tourists visited the US, that number sank to less than half a million last year.
What’s Next?
While LUXUS’s first three IPOs were diamonds, Auslander has plans to offer shares of different luxury products to investors in the near future. “We’re starting with gems and jewelry, but we want to go into other asset classes – all assets that are considered passions and pursuits.” She mentioned wine, rare watches, classic automobiles and branded jewelry could all be on the horizon. “We plan to launch a new asset during Fashion Week – a necklace that was worn by a very famous person to the Oscars in 2022.”
Auslander is offering women the opportunity to invest in something they can both see as a viable investment and love as an asset class, the way men love watches. “At first, everyone looked at me like I was crazy,” she said. “And now that LVMH has snuck into the top 10 companies in the world, and luxury is outperforming healthcare and big tech, LUXUS is getting a lot of attention and respect.”
