Diamond & Estate Trust couldn’t let our colored diamond week end without spotlighting the brown diamond, which has quickly become a luxury jewelry staple over the past few years. With celebrities such as Cate Blanchett, Hillary Swank, Lea Michelle, Cameron Diaz and Jennifer Lopez trusting the cognac diamond to complete their Red Carpet looks, you’ll be in fashionable company once you select a gorgeous brown diamond for your own collection. Here’s a quick guide to the brown diamond, also known as the cognac diamond or the chocolate diamond. A orange-brown diamond from the Diamond & Estate Trust collection. How rare are brown diamonds? Only one in 10,000 diamonds mined is a color other than white, making any colored diamond a rarity. Within the spectrum of colored diamonds , the brown diamond is in the middle of the road: a little more common than the yellow diamond , blue diamond , pink diamond , green diamond , and red diamond. But even though the brown or cognac diamond isn’t the rarest of the colored diamonds , it is still exceptional to find one naturally. Most of the world’s exquisite brown diamonds are produced at Australia’s Argyle Mine (which is also famous for champagne diamonds and pink diamonds). How do brown diamonds get their color? Because brown diamonds have soared in popularity lately, gemologists are devoting more time to understanding just what gives the brown diamond its beautiful, rich cognac color. Like most colored diamonds, a brown diamond gets its hue because of a structural irregularity in the diamond’s lattice. Some varieties of brown diamonds include golden brown diamonds, brownish orange diamonds, champagne diamonds and cognac diamonds. As with any other colored diamond , the most important word to look for in its color classification is “natural.” Diamonds treated with irradiation or other artificial methods to achieve a brown color are far less valuable and far more common than natural fancy brown diamonds. What are some famous brown diamonds?
Vibrant gems are so coveted this spring that Diamond & Estate Trust is devoting this entire week to gorgeous colored diamonds . Although we’ve all spotted celebrities wearing pink, yellow, and brown diamonds at recent Red Carpet events, there’s one colored diamond so rare that most people go their entire lives without seeing it: the green diamond. Here’s a quick primer on the legendary, elusive green diamond. A fancy vivid green diamond from the Diamond & Estate Trust collection How rare are green diamonds? If you’ve been reading our colored diamond blogs this week, you already know that all natural colored diamonds are extremely rare: Only one in 10,000 diamonds mined is a color other than white. But within the spectrum of colored diamonds , the green diamond is one of the rarest of them all (second only to the red diamond). It’s estimated that only about 10 green diamonds enter the marketplace each year, which explains why even A-List celebrities and the world’s nobility have a difficult time getting a hold of a green diamond. How do green diamonds get their color? Diamonds take on a green color when some type of natural radiation occurs while they’re forming within the Earth. Although all naturally-occurring green diamonds are extremely rare and, therefore, extremely valuable, the three most coveted green diamonds are fancy , fancy intense, and fancy vivid green. Whereas most colored diamonds are valued for a rich, deep color , green diamonds classified as fancy deep or fancy dark often lose their luster and resemble emeralds more than diamonds , making them a less desirable option. Because a green diamond is caused by natural radiation , it’s often difficult to tell whether a green diamond has been artificially heat-treated with radiation to achieve its color. Even more so than with other colored diamonds , it’s crucial to check the gem’s certification to determine that it was not artificially treated. What are some famous green diamonds? The Dresden Green The Dresden Green diamond is by far the most famous green diamond in the world. The 41 carat diamond is the largest known apple green diamond, and gets its name from the capitol of Saxony, Germany, where it has been housed for centuries. Although not as vibrantly green as the Dresden Green, the Orlov Diamond is another notable green diamond . Discovered in India, the 189.62 carat rose-cut Orlov Diamond is part of the Diamond Treasury of Russia. Its faint bluish-green tint makes it an extremely light – yet still extremely striking – example of a green diamond. Only a few green diamonds have ever been sold at auction. One green diamond, a 3.19 carat fancy green diamond ear pendant, was sold along with a yellow diamond ear pendant for $343,498 at a Christie’s auction in 2000. The largest green diamond ever sold at auction, a 2.52 carat vivid green diamond, fetched $3.08 million at a 2009 Sotheby’s auction in Geneva. What cuts work best for green diamonds? Like most colored diamonds , green diamonds look the most striking in cuts such as princess, radiant or round brilliant, all of which emphasize the depth and hue of a diamond. Green diamonds and Diamond & Estate Trust If you’re searching for the rarest, most exquisite gem the world has to offer, the green diamond is the perfect choice.

Given that we’re now in the heart of the spring season, Diamond & Estate Trust is devoting this week to this season’s most colorful, lively luxury jewelry trend: colored diamonds . Up today is the pink diamond , perhaps the most popular colored diamond of the last few years. From its striking Red Carpet presence (did you see Penelope Ann Miller ’s 3 carat pink diamond ring at the 2012 Oscars?) to its massive price tag at Christie’s and Sotheby’s auctions (one fetched more than $600,000 just last month), it’s no surprise that the pink diamond is one of the most coveted gems of 2012. How rare are pink diamonds? Just how rare is the pink diamond? If you’ve been reading our posts this week, you already know that 1 in every 10,000 diamonds mined is a color other than white. Within the spectrum of colored diamonds , the pink diamond falls somewhere in the middle: It’s not as rare as the red, purple, blue or green diamond, but it is far less common than brown, black, yellow and grey diamonds. The number of pink diamonds in the world is so few that most people will never see one of these gorgeous gems outside of a museum or auction (which may explain the world’s excitement over the recent pink diamond discovery at Australia’s famed Argyle Mine!) How do pink diamonds get their color? Whereas nitrogen gives yellow diamonds their hue, and boron causes a diamond to turn blue, scientists are still not sure what causes diamonds to take on a gorgeous, rosy hue. Still, most agree that the romantic pink color is the result of a rare atomic structure present while a diamond is forming. As with most colored diamonds, the richer and deeper the pink hue, the more valuable the gem. When it comes to pink diamonds, natural fancy deep and fancy intense hues are the ultimate sign of luxury. Capitalizing on the world’s love affair with pink diamonds, many jewelers use techniques like irradiation and heat to turn white diamonds to that desirable rosy pink hue. Just remember that natural colored diamonds are much more valuable than artificially treated ones. Want to know for sure that a pink diamond has a natural color? Check its certification! What are some famous pink diamonds? The Conde Pink Diamond The largest known pink diamond in the world is the Darya-i-Nur or Sea of Light diamond. At 175 carats, this flawless, rosy pink diamond is found in the crown jewels of Iran. Another notable pink diamond is The Grand Conde, also known as The Conde Pink, The Conde Diamond, or Le Grande Conde. At 9.01 carats, this light pink pear-shaped diamond has as much beauty as it does history. The story goes that King Louis XIII presented this stunning diamond to Louis de Bourbon, the commander of the French Army during the Thirty Years’ War. And numerous pink diamonds have gained worldwide fame at recent luxury jewelry auctions . A fancy vivid pink 5 carat diamond in a chic cushion cut fetched $11.8 million at a Christie’s Hong Kong sale in 2009. Another pink diamond from Christie’s, a 14.23 carat rectangular cut fancy intense pink diamond, fetched $23.2 million at a 2010 sale in Hong Kong. And a 6.01 carat fancy vivid blue and pink diamond ring set a world record for price-per-carat when it fetched a cool $10.1 million in an October 2012 auction. What’s the next major pink diamond to go up on the auction block? An exquisite 9 carat cushion cut pink diamond ring that copper heiress Huguette Clark inherited from her mother. Christie’s expects this gorgeously cut, perfect condition pink diamond from 1910 to go for $10 million to $15 million when it’s sold later this month. What cut is best for pink diamonds? Pink diamonds are often seen paired with white diamonds , a popular design aesthetic that amplifies the beauty of a pink diamond’s color. Radiant, princess and brilliant cuts are preferred for pink diamonds, as these cuts feature strong facets that bring out the depth and color of a pink diamond. But because a pink diamond is so romantic, many jewelers choose antique cuts not commonly seen in colored diamonds. The cushion cut, for instance, is a soft, lustrous diamond cut that matches the romance of a soft pink diamond. Which celebrities wear pink diamonds? Penelope Ann Miller stole the spotlight at the 84th Annual Academy Awards when she wore a stunning 3 carat pink diamond ring that matched the powdery pink color of her vintage gown. Jennifer Lopez was one of the first celebrities spotted wearing a pink diamond, a magnificent 6 carat pink diamond engagement ring given to her by then-fiancée Ben Affleck. Mariah Carey, Nicole Kidman, and Salma Hayek have been spotted recently wearing pink diamonds. (We can’t think of anyone who’s worn a pink diamond better than Nicole Kidman did. Did you love her Red Carpet pink diamond Bulgari necklace as much as we did?) Pink diamonds and Diamond & Estate Trust For the ultimate symbol of luxury and romance, there’s nothing more exquisite than a rare, breathtaking pink diamond. This 6.8 carat fancy intense pink radiant cut diamond in our collection has a gorgeous natural hue and a quality cut that brings this pink diamond to life.

In honor of the spring season, Diamond & Estate Trust is devoting this week to the colored diamond , spring 2012’s most vibrant jewelry trend. Up today is the blue diamond, one of the rarest colored diamonds around. Although blue diamonds have always been celebrated by the world’s nobility (think the Hope Diamond’s cursed royal legacy), celebrities such as Jay-Z and Halle Berry have catapulted the blue diamond back into the fashion spotlight. Here’s a quick guide on the blue diamond. The Wittelsbach-Graff Diamond How rare are blue diamonds? Only one in 10,000 mined diamonds is a color other than white. Within the spectrum of colored diamonds , the blue diamond is one of the rarest: only red and purple diamonds are more extraordinary than the blue diamond . The blue diamond may not be as rare as the red diamond, but these gorgeous blue gems are seldom discovered. Less than .1 percent of all diamonds mined have an intense fancy blue color . That may explain why blue diamonds command sky-high auction prices on the rare occasion when they do become available for public purchase. How do blue diamonds get their color? A white diamond takes on a deep blue hue when there’s a surplus of boron available during its formation below the Earth’s surface. The more boron found within a diamond’s carbon molecules, the more intense the diamond’s blue color becomes. When you’re determining the worth of a blue diamond, it’s safe to assume that the richest hue commands the largest price. Blue diamonds range from a deep, steely shade like the one found in the legendary Hope Diamond to a pale, subtle blue. Blue-green or blue-purple shades are less valuable than true, rich blue hued diamonds. When it comes to color , remember that naturally enhanced (heat treated) blue diamonds are far less valuable than blue diamonds with a natural color. Be sure to check a GIA certification to make sure the blue diamond you’re considering hasn’t been artificially treated to achieve its color. What are some famous blue diamonds? The Hope Diamond The 45.52 carat Blue Hope Diamond is regarded as one of the world’s most breathtaking gems. Currently housed in the Smithsonian, this steel blue cushion antique brilliant cut diamond is one of the largest known fancy blue colored diamonds ever discovered. Another famous blue diamond, the Wittelsbach-Graff Diamond , from India, sold for $24.3 million at a Christie’s auction in 2008, setting a record at the time for the highest auction price of any diamond or gem. The cushion cut diamond’s deep grayish blue color, magnificent 35.56 carat size and legendary history make it one of the most iconic blue diamonds in the world. Other notable blue diamonds include the 70.21 carat Idol’s Eye, which has a striking shape that combines the Old Mine Cut and the triangular cut; the 189.62 carat Orlov Diamond; the 35.27 carat Sultan of Morocco; and the 42.92 carat Terschenko Diamond. What cut works best for a blue diamond? Like other colored diamonds, a blue diamond’s hue is most striking when cut into a radiant, princess or brilliant cut. That’s mainly because the facets of these fiery cuts bring out the depth and hue of a colored diamond. Still, some diamond cutters , such as the one responsible for the Wittelsbach-Graff Diamond , choose a softer cut like the cushion cut to emphasize a colored diamond’s luster. Which celebrities wear blue diamonds? Jay-Z and Beyonce may have gained fanfare lately for wearing sapphires to celebrate the birth of Blue Ivy , but it seems the musicians are now moving on to even bigger, more valuable blue gems. Jay-Z has reportedly been scouring the world’s best jewelry collections this week for the ultimate fourth wedding anniversary gift for Beyonce: a gorgeous blue diamond. And Halle Berry famously wore a pear shaped blue and white diamond necklace on the Red Carpet a few years ago, garnering rave reviews from luxury jewelers worldwide.

With spring finally upon us, it only seems fitting to devote some time to the colored diamond , spring 2012’s most vibrant jewelry trend. First up in Diamond & Estate Trust’s colored diamond series is the yellow diamond , which has long been celebrated for its lively hue but has become even more vogue lately thanks to celebrities such as Heidi Klum , Jennifer Lopez and Michelle Mangan. Here’s everything you need to know about the yellow diamond. What are some famous yellow diamonds? The Tiffany Yellow Diamond When most people think of the yellow diamond, the Tiffany Yellow is the first gem that comes to mind. Discovered in 1877 at South Africa’s Kimberley mine, the Tiffany Yellow has a stunning, rich saturation. It was a magnificent 287.42 carats when discovered, but was later cut into an awe-inspiring 128.51 carat cushion cut. One of the most recent yellow diamonds to go up for auction is the 110-carat Sun-Drop Diamond . The fancy vivid yellow diamond , found in South Africa and cut in a beautiful pear shape, fetched $11.3 million at a Sotheby’s auction in late 2011. It’s the latest indication of the yellow diamond’s strong popularity. Other famous yellow diamonds include the 407.48 carat Incomparable Diamond, the 205.47 carat Red Cross Diamond, the 137.37 carat Florentine Diamond, and the 132.43 carat cushion cut Sarah Diamond How rare are yellow diamonds? One in 10,000 diamonds mined is a color other than white. Within the spectrum of colored diamonds , the yellow diamond falls in the middle of the road: it’s more rare than brown or black diamonds, but a bit more common than red or blue diamonds. But even though the yellow diamond isn’t the rarest of the colored diamonds , it is still exceptional to find one with a natural yellow hue: a mere .1 percent of all diamonds mined have an intense fancy yellow color. How do yellow diamonds get their color? A fancy intense yellow diamond Yellow diamonds get their gorgeous, lively hue when there’s a surplus of nitrogen available while a diamond is forming. The more nitrogen trapped within a diamond’s carbon molecules, the more intense the diamond’s yellow hue. When you’re determining the worth of a yellow diamond, remember that a more vibrant hue is generally more valuable. Canary yellow diamonds, which are typically pale in color, are worth less than the darker, richer intense fancy yellow diamonds (although both lately have been commanding much higher prices than white diamonds !) It’s also important to remember that naturally enhanced (heat treated) yellow diamonds are far less valuable than yellow diamonds with a natural yellow color. Be sure to check a GIA certification to make sure the yellow diamond you’re considering hasn’t been artificially treated to achieve its color. What cuts and shapes are best for yellow diamonds? Yellow diamonds are typically seen flanked by white diamonds , which provide contrast that brings out the beauty of the yellow diamond’s hue. Fiery cuts such as the radiant, princess and brilliant cuts are preferred for yellow diamonds, as these cuts have striking facets that amplify a colored diamond’s color and depth. Which celebrities wear yellow diamonds? Marilyn Monroe and the Moon of Baroda Heidi Klum made fashion waves when she selected a large, cushion cut fancy light yellow diamond ring for her engagement to then-husband Seal. Hillary Clinton wore the gorgeous Kahn Canary Diamond to Bill Clinton’s presidential inauguration in 1993, and Carrie Underwood wears a 5 carat round brilliant yellow diamond engagement ring. Cate Blanchett, Julianne Moore, and Penelope Cruz have recently chosen yellow diamonds to complete their Red Carpet looks. And we can’t forget to mention Marilyn Monroe: the jewelry icon wore the famous Moon of Baroda yellow diamond to the premier of her film Gentlemen Prefer Blondes . Yellow diamonds and Diamond & Estate Trust Diamond & Estate Trust has an exquisite collection of colored diamonds of every hue imaginable.

The Asscher cut diamond has always been one of the most coveted diamond cuts , but its strong, modern lines became even more vogue after the Asscher cut was profiled on the popular show Sex and the City. You’ll be in the company of celebrities such as Kate Hudson, Zooey Deschanel and Jessica Alba when you choose a piece of Asscher cut diamond jewelry . Who created the Asscher cut? Joseph Asscher The Asscher cut diamond was created in 1902 by famed diamond cutter and jewelry designer Joseph Asscher of the Asscher Diamond Company (now called the Royal Asscher Diamond Company). Soon after Joseph Asscher debuted his new diamond cut, the world was captivated. The Asscher Diamond Company, which Joseph’s father had founded in 1854, patented the design and maintained exclusive rights of the Asscher cut until World War II. What does the Asscher cut look like? An emerald cut diamond, left, and an Asscher cut diamond. The Asscher cut is similar to the emerald cut in that it has a similar striking pavilion cut with rectangular facets that highlight a diamond’s clarity and depth. The main difference between the emerald cut and the Asscher cut is that the Asscher cut is square rather than rectangular. The Asscher cut was designed to draw your eye to the diamond itself rather than wow you with flash; that quality makes it an ideal diamond cut for an engagement ring . What is the Royal Asscher cut? About 100 years after the Asscher cut was created, two relatives of Joseph Asscher debuted the Royal Asscher cut. Known for its unparalleled light performance , the Royal Asscher cut features one extra break on the diamond’s pavilion, which gives this cut 74 facets instead of the Asscher’s 58 facets. The Royal Asscher Diamond Company holds the patent for the Royal Asscher cut, which debuted in 2001. The Asscher cut and Diamond & Estate Trust If you prefer a strong, modern cut that emphasizes a diamond’s color and depth, the Asscher cut is the perfect choice. This exquisite, 4.65 carat Asscher diamond in the Diamond & Estate Trust collection is the epitome of a precise diamond cut. With striking facets and a perfectly symmetric signature Asscher shape, this GIA certified diamond isn’t one you’ll easily forget. Diamond & Estate Trust is the premier luxury jeweler buyer and seller in Los Angeles, Southern California and beyond. We specialize in vintage jewelry , signed designer pieces, watches such as Rolex , Audemars and Patek Philippe , and loose gems such as diamonds , rubies and sapphires .

Birthstones have been around since ancient times, and first gained mainstream popularity during the 14 th and 15 th centuries in Poland. Although birthstones have varied across cultures and time periods, one thing is certain: the month April has been associated with the diamond ever since the National Association of Jewelers created the modern birthstone list in 1912. More than any other month, April is associated with rebirth, renewal and the Earth’s natural life cycle. When you look at it this way, the diamond is a fitting choice for the April birthstone: the precious gem is a result of carbon formations that grow deep below the Earth’s surface over a long period of time. When a diamond finally is discovered or mined, and eventually ends up in your hands, it’s truly a symbol of the life cycle. A diamond is classic and beautiful any month of the year. But given the gem’s association with April, now is the ideal time to invest in a gorgeous colorless diamond. This timeless 4.01 carat pear shaped diamond in our collection has all the warmth and simple sophistication of an April afternoon. Its gorgeous G color grade and quality cut make this diamond luster from every angle, and with an internally flawless (IF) clarity grade, this loose gem has a striking natural beauty all its own. With such a classic cut , this pear shaped diamond would be perfectly suited for a simple ring setting or as a timeless pendant. This diamond has all the warmth and life of the spring season, but is beautiful enough to carry you through all 12 months of the year. Are you looking for a diamond with more fire or flash? Do you prefer a cushion cut, emerald cut, or Asscher cut diamond? Diamond & Estate Trust’s exquisite collection of loose diamonds includes diamonds of all shapes and sizes. We’ll help you find the perfect loose stone and will even incorporate it into a custom piece made with your style sensibility in mind. And for a piece of vintage diamond jewelry, view our estate collection, which contains pieces ranging from Victorian to Art Deco eras and beyond.

History is filled with famous families such as the Kennedys, the Rockefellers and the Rothschilds. But in the world of luxury jewelry , one family towers above the rest. With six generations of renowned diamond cutters in its family tree, the Tolkowsky family has been synonymous with some of the world’s most beautiful gems since the 1800s. Marcel Tolkowsky The Belgian Tolkowsky family first got involved in the precious gem industry in the 1800s (when Abraham Tolkowsky began trading gems), and was credited with its first major diamond invention in the 1870s (when Maurice Tolkowsky created the diamond bruting machine). But it was a generation later that the first Tolkowsky gained worldwide fame. Marcel Tolkowsky is known as the father of the modern round brilliant cut diamond, one of the most popular diamond cuts today. A mathematician at heart, Marcel discovered the most ideal symmetry for cutting diamonds to achieve maximum brilliancy . This measurement, which included 58 facets to maximize the amount of brilliance and reflected light, is known as the Ideal Cut, Tolkowsky Cut or Tolkowsky Brilliant. Marcel died in 1991, leaving behind a legacy of diamond cutting expertise that is still carried on today by his nephew Gabriel Tolkowsky. Gabriel (Gabi) Tolkowsky Trained primarily by Marcel, Gabriel Tolkowsky is one of the world’s foremost diamond cutting experts. The master diamond cutter invented flower cuts in the mid-1980s, and has been one of De Beers’ go-to gem consultants ever since. Gabi gained worldwide recognition for his work as master cutter for the Centenary Diamond . At 273.85 carats, the gem is known as the world’s largest internally flawless diamond. It took Gabi and his team three years to cut the Centenary Diamond into its intricate, 247 facet shape, and the team reportedly hand cleaved the massive gem in order to avoid heating-related damage that often results from using saws or lasers. The Tolkowsky’s De Beers Centenary Diamond was unveiled to the world in 1991 and has since joined the ranks of the world’s most exquisite diamonds . Gabi also designed and cut the Golden Jubilee Diamond, a magnificent 755.5-carat rough stone that was presented to the King of Thailand. The final version of the Golden Jubilee Diamond is one of the most stunning examples of a cushion cut that the world has ever known. Boasting 545.65 carats and 148 precisely cut facets, this diamond furthered Gabi’s reputation as the world’s foremost diamond cutter. Gabi also developed the first triple brilliant cut diamond, displayed in the famous Gabrielle Diamond, which has 105 facets and striking brilliance and fire. When it comes to diamonds , rubies , sapphires or other gems , nothing is more important than a quality cut . Diamond & Estate Trust’s collection is filled with exquisite, hand-picked loose gems that exhibit perfect facets and fire. In honor of Marcel Tolkowsky’s celebrated round brilliant cut, consider adding one of our round diamonds to your personal collection . Diamond & Estate Trust is Southern California’s premier luxury jewelry buyer and seller . Our gem experts only select the most beautifully cut diamonds for our exquisite collection .
