Behold the Gem Collector’s Trophy Diamond ‘The Heart of the Maldives’

By Steven Joseph

“No fancy colored diamond collection is complete without a green stone,” said David Federman, expert gem author in Modern Jeweler. “But since, next to red, green is probably the rarest of all natural diamond hues, most collections lack representation from the green portion of the diamond rainbow. Even when they do contain greens, the stones’ color is usually not a bona fide natural one — or at least not classified as such by a gem lab of stature.

Well then, behold here a diamond that would complete a fancy colored diamond investor’s collection. David Rosenberg, president of the Southeast United States Diamond Bourse, was recently presented this masterpiece he calls “The Trophy” –  an extremely rare 4.16 carat fancy intense blueish green diamond – by its owner who was interested in bringing it to market.

The diamond is the centerpiece of an absolutely breathtaking piece of jewelry. The blue-green precious stone, certified as a natural colored diamond, is surrounded by a halo of 14 Argyle pink diamonds, mounted on a band of 18k rose gold with two additional Argyle pink diamonds. “When I saw it (the ring), it spoke to me,” said Rosenberg.

The Provenance
For “The Trophy” to turn this gem aficionado’s head speaks volumes. Rosenberg was the subject of a feature in this magazine two and a half years ago, profiling his rise to the most-respected authority on fancy colored diamonds, his self-made background, and his ascension as the youngest president in the diamond bourse’s history. Recently, the Argyle mine in Western Australia, famous for its pink diamonds, named Rosenberg one of just five ‘Select Ateliers’ in the United States. “Many of the diamonds that come out of the mine are pink, but there are also some red, some purple, and some blue. But I am the only retailer in the United States to whom they are providing their larger and more important stones,” explained Rosenberg. The Argyle mine produces 90 percent of the world’s pink diamonds, and its imminent closure in 2020 means the stones are about to become even harder to come by.

The Story Behind Pink Diamonds
Pink diamonds are shrouded in myth and mystery. “The mysterious alchemy that results in the pink coloration of Argyle diamonds is tied up with a very unique combination of temperature and pressure, deep within the earth’s surface, occurring 1.6 billion years ago.  It is in fact an unfathomable randomness, created and limited by nature,” said Marie Chiam, Marketing Manager for Rio Tinto Diamonds.

Recent Auction Results
Recent auction results have seen many rare fancy colored diamonds sell at over $1 million dollars per carat, but this is no surprise to Rosenberg. “Natural colored diamond stones have always been of interest, especially from royalty. But in the last decade or so, the important intrinsic investment value that rare natural fancy colored diamonds bring to a well-balanced portfolio has become more well-known.” Rosenberg elaborated, “The colors are extremely rare. And now the affluent want to diversify their wealth. So they have part cash, part stocks, part art, and part real estate. But they also want something tangible, something portable – like rare fancy colored diamonds.”

How Natural Blue Green Diamonds Get Their Color
The two colors present in the center stone of this Trophy Diamond, blue and green, are two of the rarest colors for diamonds to achieve certification. Blue is only present in diamonds if there was some of the element boron in the carbon during the diamond’s formation. And green can only be found if the diamond is naturally irradiated by exposure to a radioactive element after formation, most commonly uranium. “Green is one of the hardest colors to be certified, because you had a lot of jewelers radiating their diamonds artificially,” said Rosenberg. He continued, “To get a diamond certified green, you have to start with the rough stone, and polish it just a little bit at a time, constantly sending it back and forth to the GIA so they can document that it’s still the same stone.” Most green diamonds still have a little bit of the original skin on at least one of the facets of the stone in order to maintain their authenticity.

Rosenberg once said he wouldn’t recommend a diamond unless it had a story to tell, and the blue-green at the center of the Trophy Diamond certainly tells a sweet tale. “When I set my eyes on the stone, I was immediately reminded of the calm and crisp waters of the Maldives,” Rosenberg said. And so he refers to the stone as ‘The Heart of the Maldives’ in the island’s honor. He continued, “The island is very serene and luxurious, just like the ring. It is also located near the equator, and so I feel like when you wear this ring, you’ll find balance.”
