8 Rare Fancy Diamonds

Gemstones are already considered rare, and diamonds are among the rarest. Of the most desirable diamonds, the ones that are the closest to colorless are typically desired. However, on the opposite side of the spectrum, once a diamond’s color reaches vivid, you have an extremely valuable fancy-colored stone. Fancy-colored diamonds come in all shades of the rainbow, some easier found than others, but these colorful gems are rarer than most D-colored diamonds. Check out this list to see some of the most valuable fancy diamonds in the world.

8. The Moussaieff Red
Red diamonds are some of the rarest fancy-colored diamonds — only 20-30 have been discovered, and the majority are around a half carat.The Moussaieff Red is the largest ever discovered. When first discovered in Brazil by a fisherman in the ’90s, the raw stone was 13.9 carats. However, the internally flawless stone had to be cut to 5.5 carats. The stone was bought in the early 2000s by Moussaieff Jewelers for about $8 million — that’s almost $1.5 million per carat.

7. The Dresden Green
This 41-carat diamond has a long history that can be dated back to a 1722 London news article about the stone. The rare green gem likely originated in India, but was then bought in 1942 by a London jeweler. The stone eventually made it to the Green Vault of Frederick Augustus I, the first King of Saxony. The King had it reset in 1768, the setting in which the stone remains.

The gem was on display in Dresden until the beginning of WWII when it was moved for safekeeping. However, the USSR took the jewels to Moscow during the war. The USSR returned the jewels in 1958.

6. The Sun-Drop Diamond
The Sun-Drop diamond is the largest known yellow diamond. This massive diamond is estimated to have formed in Earth’s crust 1-3 billion years ago. The fancy vivid yellow weighs a massive 110.3 carats and is cut into a pear shape.

In 2011, the Sun-Drop broke a world auction record for a yellow diamond, selling for $10.9 million to an anonymous bidder. However, the record has since been beat by the 100-carat Graff Vivid Yellow, which sold for $16 million.

5. The Ocean Dream
Name for the blue-green hue that brings the ocean to mind, the Ocean Dream is exceptionally rare as the first and one of the only diamonds naturally colored ever discovered.

The stone is also remarkably large at 5.51 carats and it was found in Central Africa, but the mine and exact origins are unknown. It was auctioned by Christie’s in 2014 as a ring set in gold and platinum with pave set white and pink diamonds. It sold for over $8 million to an unknown bidder.

4. The Spirit of de Grisogono
The Spirit of de Grisogono is notable on two accounts. First, it’s the largest black diamond ever discovered. Second, it’s also the fifth largest cut diamond. The massive raw stone was 587 carats before cutting.

In the end, the moghul-cut diamond weighs in at a whopping 312.24 carats. The stone was mounted in white gold set with 702 smaller white diamonds which totaled 36.69 carats. The owner and sale of the ring is unknown. However, it’s said that the Swiss jeweler de Grisogono has sold the ring.

3. The Golden Jubilee Diamond
This is the largest cut and faceted diamond in the world. The fancy brown diamond weight 755.5 carats before it was cut to 546.67 carats. It’s also the largest brown diamond known.

The stone was discovered in 1985 in South Africa, and it was first thought to be an ugly stone. Now, with improved cutting technology, brown diamonds are coveted champagne diamonds. The cutting process took De Beers two years. After a series of transactions, the stone was gifted to the King of Thailand Rama IX for the 50th anniversary of his coronation in 1997.

2. The Pink Star
This vivid pink diamond is the largest of its color to have been discovered. It was mined in South Africa by De Beers in 199. The pink diamond weighed 132.5 carats in its rough state. The diamond was then cut to 59.6 carats.

In 2013 the gem broke a world record at a Sotheby’s auction, with the stone selling for about $83 million — the most paid for a gemstone of any kind at auction. However, Sotheby’s had to buy the diamond back after the buyer from the auction didn’t pay and defaulted. Sotheby’s had guaranteed the original seller $60 million and had to pay in accordance to their agreement. Now, the diamond remains in Sotheby’s inventory valued at $72 million.

1. The Hope Diamond
The hope diamond is known as the most famous diamond in the world with a long and detailed history as one of the rarest gemstones in the world. The vivid blue weighs 45.52 carats. The origins are unknown as transactions only suggest that a French gem merchant may have obtained the gem in the 17th century. However, the gem is believed to have been mined in India.

Since the gem was discovered, the gem has passed through many hands, including Kind Louis XIV of France, King George IV of the U.K., Pierre Cartier and Harry Winston. Now, it resides at the Smithsonian Museum in Washington, D.C. The diamond has been surrounded by mystery and tales of a curse that affects the owner and wearer of the diamond. It’s valued between $200-250 million.

Pretty in Pink: The Best Rose Gold Styles

Rose gold was a shade recently considered antique, vintage and retro. Now, the shade has made a comeback due to its universally complimentary tone and its soft and glowing appeal — a perfect combination that allows fashion to flourish. The pinkish shade of gold has even found itself replicated in clothing, shoes and any other non-metal fashion form.

Not sure how to style your rose gold jewelry? We made a list of our jewelry styles featuring the pink gold and assorted counterparts so you could find the right style for you.

1. Two-Tone

[Tacori Link Bracelet][Snake Ring][CZ Halo Ring][Bulgari Serpenti Ring]

Rose gold and white gold combined create a beautiful variation on the classic engagement ring. The modern style creates a delicate and feminine look that could be confused as vintage if it weren’t for the unmistakable modernity of the intricate designs.

Though the combination makes for a beautiful engagement ring, it makes other jewelry styles more interesting too. Alternating links of sterling silver or white gold with rose gold add a subtle quirk to an otherwise standard chain link bracelet or necklace.

2. The Stacking Trend

[Cartier Juste un Clou Bracelet][Diamond Link Bracelet][Cartier Love Bracelet]

This is a union of two of our favorite styles — stacking and rose gold. Go monochrome in pink with layers of pink gold-toned bracelets. Stacking is on trend this summer and it’s a look that’s easy to achieve.

To perfect the look, you need to stack with the right balance, otherwise your stack could be monotonous, or worse, excessive and gaudy. The trick is to use bracelets of different sizes, styles and textures. Our favorite is the sleek simplicity of a Cartier Love or Juste un Clou bracelet combined with a dazzling chain link bracelet set with pave diamonds.

3. Watch Style

[Michael Kors Camille][Bulgari Serpenti][Cartier Ballon Bleu]

Women’s watches are sometimes a clunky accessory that serves a functional purpose instead of a fashion purpose. But we dare to ask “Why not both?” Some of our favorite watch designs featuring rose gold are as functional as they are beautiful.

Whether you would like a casual watch for special occasions, then rose gold could be the perfect choice for both. The universal shade pairs well with nearly every color under the sun, making it a safe bet when you don’t know what you will be wearing in the future.

4. Double the Pink

[Sapphire Bow Ring][LeVian Rose Quartz Ring][Bird and Flower Brooch][Flower Ring]

One of the best ways to bring out the pink tint of the gold is to compliment the metal with a pink stone. Stones of the pink variety can be found in many forms, but the most popular are pink sapphire, rose quartz and pink topaz.

Rolex: The History Behind the Iconic Brand

Rolex. The brand’s name has grown to become synonymous with quality, prestige, and luxury over the years. While we’re certainly all familiar with the dark green color and the iconic crown that sits atop its logo, how much do you actually know about the famous watch company? If you’re curious about the history of the Rolex brand, we’ll walk you through the company from its founding to its present-day prosperity.

Check out the history of legendary Rolex watches, from TrueFacet!

Founders Alfred Davis & Hans Wilsdorf

Rolex was initially founded in 1905 in London by Alfred David and his brother-in-law Hans Wilsdorf. Wilsdorf was just 24 at the time, but he was driven to design a wearable wristwatch that was more precise and elegant than the existing models of the time. Wilsdorf chose the name Rolex because it was easy to pronounce, easy to remember, and which would look elegant on the watch face detailing. After trying out countless iterations and combinations, Wilsdorf claimed that “a genie whispered Rolex in my ear” while he was riding in a horse-drawn carriage along Cheapside in London.

Rolex Innovation and Developments

Rolex always kept the mission in mind to create a higher quality watch with more chronometric precision. Realizing their efforts in 1910, the Official Watch Rating Centre in Bienne awarded Rolex the first-ever Swiss Certificate of Chronometric Precision to a wristwatch, the first of many record-breaking firsts that the company garnered. By 1920, the company had moved its headquarters to the international watchmaking hub of Geneva, where it developed the first waterproof and dustproof watch thanks to a hermetically sealed case.

In the early 30’s, the company patented the first self-winding mechanism and rotor, which still drives modern automated watches to this day. Rolex continued its string of innovations with the development of the first Datejust in 1945, giving wearers a date indication in a window on their watch face.

The company began developing watch models that were suited to professional use as well as more rugged excursions, equipping climbers who summited the heights of Mount Everest and gracing the wrists of deep sea divers and submariners.

Moving on to the mid-eighties, Rolex pioneered the use of 904L steel in the use of all of its watch cases. While the steel had been primarily in use for aerospace, chemical, and high-tech industries, Rolex adopted its highly anti-corrosive qualities to deliver an exceptional polish and shine to its watches that would last over the years.

Rolex Today


Today, Rolex is the world’s largest luxury watch brand, making around 2,000 watches per day. The company is headquartered in Geneva, Switzerland, and is owned by the Wilsdorf Foundation. In 2014, Forbes ranked Rolex as one of the world’s most powerful global brands, at number 72.

Sybil & David Yurman: The Spirit of the Brand


David Yurman is one of the most widely recognized names in the jewelry industry, but not many of us could give a detailed history of the company’s founders and background. As one of the most popular designers among TrueFacet customers, we figured we could do a little digging and give you some information about the couple behind the brand.

Check out the background of David Yurman jewelry, from TrueFacet!

Early Life

Originally from Long Island, David Yurman began his first forays into metalwork at the young age of 16. Working with the sculptor and welder, Ernest Gonzales, Yurman learned technical skills in welding and metalwork that would lead him to start experimenting with jewelry design later on. After a stint at New York University, Yurman traveled around the country, hitchhiking to bohemian enclaves like Greenwich Village, Big Sur, San Francisco, and Venice.

After an apprenticeship with Jacques Lipchitz, the well-known modernist sculptor, Yurman began a Greenwich Village-based sculpture studio. He later worked with the sculptor Hans Van de Bovenkamp, at whose shop he met painter and his future wife, Sybil Kleinrock. The pair moved upstate to Carmel, New York, where they started a fine sculptural jewelry company, Putnam Art Works and began their foray into jewelry.

Starting the Company

With Putnam Art Works, David and Sybil displayed their paintings, sculpture work, and artisanal jewelry designs around the country. After their marriage in 1979, the couple started the company we know today. With output like their David Yurman earrings to their signature cable bracelets, we couldn’t be more thrilled they took the plunge to start their jewelry venture.

Establishing the Brand

At the Basel, Switzerland-based 1987 World Watch and Jewelry Show, Yurman displayed the company’s designs to a global audience. The company began to pick up speed as the couple gained traction with buyers in international markets.

In what would come to be his most iconic design, Yurman released his first twisted helix cable bracelet in 1982. He christened the gemstone capped bracelet and its associated pieces the Renaissance collection, the popularity of which has persisted to present day.

As the brand grew, the couple introduced their first advertising campaign in 2000, featuring a St. Barths-based photoshoot with Amber Valleta from fashion photographer Peter Lindbergh. With a more prominent emphasis on advertising in recent years, the brand has featured shoots with supermodels like Gisele Bündchen and Kate Moss.

David Yurman has garnered recognition and awards in the industry over the years like the Star Gazer aware from Fashion Group International, the Lifetime Achievement Award from the American Gem Society, the Couture Human Spirit Aware from the Couture Show, and the Annual Visionaries Award from the Museum of Arts and Design.

David Yurman Today

These days, David Yurman has been flourishing as an internationally renowned jewelry company, known for its fine quality gemstones and metals. The global juggernaut has expanded to its current footprint of retail locations in sixteen states and four countries in North America, Europe, and Asia.

The couple has also demonstrated a commitment to giving back to the community with their David & Sybil Yurman Humanitarian and Arts Foundation. The foundation supports volunteer-work and donations to the arts and various other charitable organizations like the Whitney, The Breast Cancer Research Foundation, as well as the Make-A-Wish Foundation.

5 Jewelry Trends to Try this Summer

It’s already July and we have two more months of summer ahead of us. If you want to stay on trend for the summer, or perhaps refresh your look, then we’ve got you covered. Check out five of the best summer jewelry trends below — there’s a trend for everyone.

1. Color Burst


[Green & Pink Tourmaline Necklace] [Kate Spade Bib Necklace]

This summer, add a colorful accent to your wardrobe. You can make any look more interesting by adding a bold statement necklace. If bright shades aren’t your style, then substitute the bright for pretty pastel shades. Adding a colorful piece is an easy way to liven up an outfit that could otherwise be dull, making this trend a refreshing change for the summer.

2. Statement Earrings


[Orange Carnelian Necklace][Pink Sapphire & Diamond Earrings][Chanel Logo Earrings]

If you think the statement necklace trend seems a bit tired, try this trend out instead. The statement earring looks is a toned-down version of the statement necklace. With bold designs and colors, this style is a less pronounced accessory that doesn’t sacrifice style.

3. Art Deco Inspired


[Sapphire Ring][Diamond, Sapphire & Ruby Charm Bracelet][Ruby & Diamond Bracelet]

Art deco is making a comeback. For the spring/summer fashion season, many designers, including Dolce & Gabbana, accessorized their runway looks with the vintage, geometric and colorful designs. Art deco-inspired jewelry is vintage with an edge, perfect for adding whimsical flair to a modern look.

4. Light as a Feather


[Diamond Feather Ring][Tiffany & Co. Feather Earrings][David Yurman Feather Bracelet]

Boho has remained a strong trend throughout the season. After trendsetters made appearances at the Coachella festival, the fate was sealed. Add a touch of luxury to the feather look to remain current and polished while still on trend for the summer season. Adding gemstones or precious metals will give you the boho charm without sacrificing the splendor of fine jewelry.

5. Natural Stones


[H. Stern Multicolor Bracelet][Damiani Rough Diamond Maji Bracelet]

Similar to the boho look, the rough stone looks is all natural. Unpolished and cut gemstones prove to be just as beautiful with this colorful trend. Find your favorite stone and wear at is you would find it naturally. Colorful or natural, geometric or round, there’s the perfect stone for your style.

Breakfast at Tiffany’s: The Costumes and Jewelry

“Well, when I get [the mean reds] the only thing that does any good is to jump in a cab and go to Tiffany’s. Calms me down right away. The quietness and the proud look of it; nothing very bad could happen to you there.” – Holly Golightly, Breakfast at Tiffany’s

It is hard to over-emphasize the cultural significance of the classic film Breakfast at Tiffany’s.

The comedic-yet-tragic story follows the transformation of Holly Golightly (played by Audrey Hepburn) from Texan wild child to a refined and polished wannabe-socialite– a title she hopes to achieve through questionable means. Meanwhile, Holly Golightly’s wardrobe has become a coveted and admired collection unto itself. We explore the iconic costumes and jewelry that were such an integral and significant part of the film.

The Opening Scene Black Dress and Pearls
The audience is introduced to the striking Ms. Golightly as she elegantly steps out of her cab in the wee hours of the morning and seemingly floats towards the New York Tiffany & Co. store windows. Her column dress was designed by famed French designer Hubert de Givenchy, a personal friend of Audrey Hepburn. The dress was so fitted for Hepburn’s narrow frame, two were actually made: one for standing at the windows and one for walking which had a long slit down the side.

Holly dons a pair of satin elbow-length gloves, her tortoiseshell Oliver Goldsmith sunglasses and ropes and ropes of pearls. Her layered pearl necklace was designed by Roger Scemama. Scemama was a French jewelry designer who frequently collaborated with the haute-couture design houses including Givenchy, Dior, Lanvin, and Yves Saint Laurent. The necklace neatly falls down Hepburn’s shoulders and back to emphasize the low-cut back of the dress.

The House Party LBD and Maxi Necklace

Early in the film, Holly Golightly invites her neighbor Paul Varjak(played by George Peppard) over for a drink at her apartment. The party quickly escalates from a low-key happy hour to a debaucherous and booze-fueled bash.

Even in the apartment packed with party-goers, Holly shines and stands out in her little black dress and statement necklace. This LBD is the film’s second design by Givenchy. This day dress is made in a cloqué silk and is so refined in its simplicity, hugging Hepburn’s willow frame, before it flirtingly flares out at her knees.

Devotees will notice: Holly wears the same dress when she first meets her new neighbor Paul. Paul is mystified by Holly’s unusual lifestyle and, when Holly pairs her black dress with a wide-brimmed hat and over-sized sunglasses, her look only heightens her enigmatic allure. The audience sees the dress again (this time with a campy hat and brilliant diamond earrings) when Holly learns her ex-husband Doc Golightly is in New York.

For her party, though, Holly wears her trusted dress with an impressive-looking bib necklace. The necklace is made of glass beads, plastic pearls and black painted enamel chains. It is most definitely a piece of costume jewelry. Although the designer is not known, most credit its general concept to Breakfast at Tiffany’s costume designer Edith Head.

And we cannot overlook Holly’s hairdo; her party look is complete with blonde streaks that accentuate the height of her bouffant.

The Breakdown Pink Dress and Tiara
In a pivotal scene, Holly returns to her apartment with her new Brazilian beau Jose da Silva Pereira (played by José Luis de Vilallonga). The couple have been out partying but her happiness is snuffed out when she reads a telegram informing her that her beloved brother Fred was killed in a Jeep accident while serving in the war. Holly’s brilliant and cheerfully pink dress stands in sharp contrast to her crushing grief.

This hot pink silk cocktail dress is dotted with fan-shaped green rhinestones and a wide pink ribbon belt, tied in an over-sized bow. Casually draped over her shoulder is a matching pink collarless, three-quarter sleeved coat. To finish her cheeky outfit, a pink rhinestone tiara is perched in Holly’s up-do.

The dress sold at a Christie’s auction in 2007 for a whopping $192,000 USD—more than six times its pre-sale estimate.

7 Most Popular Designs by Cartier, Rolex, and Tiffany & Co.

We explore the everlasting designs from renowned brands that drew fans in with their timeless style, rich backstories and groundbreaking engineering. Here are the top seven most-coveted items from your favorite luxury brands.

7. Tiffany Heart Pendants

The ubiquitous “Please Return to Tiffany & Co.” charm has been a fan-favorite since it was introduced in 1969. The pendants were initially part of a customer service initiative and came stamped with a registration number so, if the item was lost and returned to Tiffany & Co., the store could easily contact the owner.

Designer Elsa Peretti’s Open Heart design is another 20th century Tiffany & Co. classic. Peretti joined Tiffany & Co. in 1974 and is one of only four designers to sign her work with the famous jewelry maison.

6. Bulgari B.Zero1 Ring

Bulgari’s B.Zero1 Ring brings together two of Bulgari’s most-recognized design motifs: the serpentine-like tubogas chain and its Roman-lettered logo. Of the B.Zero collection, which was introduced at the end of 1999, the B.Zero1 ring stands out as the collection’s clear leader. Fans have flocked to its striking and distinctly Bulgari design and the ring’s symbolism of the harmonious past, present and future and the start of all new beginnings.

5. Omega Seamaster

The Omega Seamaster was launched in 1948 as a part of Omega’s 100th anniversary celebration. This dive watch was considered an improvement upon Omega’s first water-resistant watch, the Marine. Since its release, the Omega Seamaster has been a part of many diving records. In 1955, an Australian diver wore an Omega Seamaster 63.5 meters under water. In 1970, French divers set another record while wearing their Omega Seamaster watches. The group dove to depths of 253 meters. The following year, the Seamaster was taken to depths of 1,000 meters.

The Omega Seamaster also most recently graced the wrist of James Bond, first worn by actor Pierce Brosnan in 1995’s Golden Eye and later Casino Royale’s Daniel Craig in 2006. Still going strong today, the Seamaster remains the oldest line in the current Omega collection.

4. David Yurman Cable Bracelet

David Yurman’s trademark cable-motif is a mainstay of nearly every David Yurman collection since it was introduced in 1983. The bracelet was first made with an automotive cable-winding machine. The David Yurman Cable Bracelet also ushered in a new standard in jewelry-making by being the first bracelet to feature diamonds set in sterling silver.

3. Chanel Logo Earrings

Coco Chanel’s mark on the fashion industry cannot be overstated enough. She introduced the now-universal “Little Black Dress,” popularized costume jewelry and cultivated one of the world’s most recognized and coveted brands. But it’s that striking logo of interlocking C’s that catches everyone’s attention; today the Chanel logo earrings are a quintessential jewelry collector’s piece.

2. Rolex Oyster Perpetual GMT-Master II

In 1954, Pan Am Airways tasked Rolex with designing a top-quality watch for their pilots and navigators. The result was the Rolex GMT Master which allowed pilots to easily switch between the aeronautic-standard Greenwich Main Time (GMT) and other time zones by simply rotating the bezel. The watch was worn by pilots on Pan Am’s first non-stop intercontinental flight between New York and Moscow.

This professional watch has remained a Rolex classic ever since. Over the years, Rolex has modified the design, including a metal bracelet to elevate it to coveted dress watch. Additionally, wearers can now set their Rolex GMT to a second time zone without rotating the bezel, which also allows for a third time zone to be read.

1. Cartier Love Bracelet

It’s no real surprise that this Cartier staple tops out this list of all-time favorite jewelry designs. The Cartier Love Bracelet carries the vintage appeal of its 1969 design and has undergone a recent pop culture resurgence. More fashionable than ever, the Cartier Love Bracelet has even won over male wearers to only broaden its appeal. The bracelet was designed by Aldo Cipullo who drew inspiration from an unlikely source: the possibly-fabled medieval chastity belt. Cipullo, however, emphasized the bracelet as a symbol of love, fidelity and devotion– and not barbaric practices. Today, the bracelet adorns the wrists of many celebrities, including Pippa Middleton, Cameron Diaz, Katie Holmes, Jennifer Aniston, Kanye West and, most famously, the Kardashian and Jenner families.

How to Spot a Fake Diamond: Easy DIY Tests

If you’ve recently come into possession of family heirlooms or made a purchase online, you might be apprehensive about your diamond’s authenticity.

The only way to know with absolute certainty if your diamond is authentic is to have it professionally appraised. However, there are at-home tests you can conduct before paying an appraiser.

Here are our seven best tips for spotting a fake diamond.

1. Use a loupe to magnify any visible imperfections.
A loupe is a type of magnifying glass used by jewelers and watchmakers. You can purchase a loupe online, at a jeweler’s or craft store. Closely examine your stone with the loupe. Because real diamonds are naturally occurring, they often have internal imperfections. When examining your stone, look for small signs of imperfections to signal a genuine diamond. Natural diamonds may be flawless but, bear in mind that, lab-grown diamonds (diamonds that are synthetically produced in controlled environments) may look flawless under the magnifying glass as well.

A chart used to examine diamonds and to determine and grade the quality of their imperfections

A related note on synthetic diamonds: while these tips can suss out a white sapphire, topaz or cubic zirconia from a diamond, it is nearly impossible to decipher a natural diamond from a lab-grown one. If you suspect that your diamond is synthetic, bring it to an expert for closer examination. While these lab-grown diamonds are still valuable, they are slightly less so than naturally-occurring diamonds.

2. Examine the stone’s edges.
While a fake will have rounded, dull edges, a real diamond’s edges are sharp and exact.

3. Consider the diamond’s mountings.
Most diamonds are set in a precious metal like gold or platinum. If the stone’s mounting appears to be plated or is only a semi-precious metal (like copper or aluminum), the diamond itself may be fake. Similarly, if the setting looks sloppy or like poor-quality craftsmanship, the diamond may not be particularly valuable.

4. Conduct the “Fog Test.”
A quick and easy test to determine if your gem is a real diamond: breathe on the stone, exhale as if you’re trying to fog a window or clean your glasses. If the surface of the stone fogs, it is not a diamond. Diamonds do not retain heat well so, even when hit with your breath’s warm air, they will not fog.

5. Try the “Transparency Test.”

Internally, diamonds sparkle grey and white; this is known as the diamond’s brilliance. Meanwhile the rainbow light reflected off a diamond is called its fire. This important distinction helps separate a real from fake diamond; look into your diamond and if you see a colorful sparkle inside the stone, it’s likely a counterfeit.

Similarly, if you have a loose diamond, place it atop a newspaper, over a line of text. A genuine diamond’s brilliance should sparkle enough to keep you from reading the underlying print through the stone. The type beneath other stones like a cubic zirconia, however, will be legible through the gem.

6. Drop the loose diamond in water.
If your stone is not set, try a water test. Simply place the stone in a glass of water. Diamonds are very dense and will sink to the bottom of the vessel. Fake diamonds, alternatively, will float at the top or fall only to the middle of the glass.

7. Test the diamond with sandpaper or heat.
A word of caution before proceeding with either of these at-home tests: If your stone in question is not an authentic diamond, these experiments will damage your stone. We strongly suggest only using these tests if you are indifferent to ruining your stone in the event it proves unauthentic.

In the first experiment, rub a piece of sandpaper against the stone. Diamonds are one of the hardest naturally-occurring minerals so, if it is scratched by sandpaper, it’s most likely not a real diamond.

The second test works only for loose stones. Heat the stone over a lighter for 30 seconds and immediately drop it into a glass of water. A real diamond will be unaffected by dramatic changes in temperature and it will simply fall to the bottom of the glass. Fake diamonds however will shatter immediately.

8. Bring in the experts.
To definitively know if your diamond is real or fake, bring it to an expert appraiser. If you do not have a go-to jeweler, look for an appraiser that is a certified gemologist and belongs to an appraisal association or organization. On average, a diamond appraisal will cost $50 or more. If you’re quoted a significantly lower rate, proceed with caution as it may be a rushed or less thorough evaluation process.
