Golconda Diamond

Exceptionally pure, incomparably beautiful and vanishingly rare, legendary Golconda diamonds are among the most desirable gemstones on earth.

Worn by Maharajas and royalty, and prized for centuries for their peerless beauty, rare Golconda diamonds are true gem collectors’ gems.

Golconda diamonds were the first diamonds ever discovered by man. They glittered in the riverbeds of the Golconda region of India, a few kilometres from Hyderabad, in the early 16th century. Mankind had never seen diamonds before; let alone stones this hypnotically transparent, brilliant and beautiful.

Golconda diamonds are formed of pure carbon, completely devoid of chemical impurities. They are among the cleanest, most transparent and intensely brilliant diamonds on earth, possessing ‘ultra-limpidity’ - like looking through icy, pure mountain water.

Known as Type IIa diamonds, chemically pure stones account for less than two percent of the world’s natural diamonds. But even amongst Type IIa diamonds, Golconda stones are unique, thanks to their near-mythical legacy.

They were believed to be a gift from the Gods, and were reserved for the Maharajas, who wore them as much as protective talismans as symbols of power. Until diamonds were discovered in Brazil in 1725, they were the exclusive preserve of royalty and aristocracy. It’s no wonder that in the diamond industry, the word ‘Golconda’ is shorthand for stones of incomparable quality.

Many of history’s most famous diamonds originated from Golconda mines, including the Hope diamond, the Farnese blue and the Koh-I-Noor - part of the Crown Jewels, said to have been buried deep in a lake near Windsor Castle during the Second World War for safekeeping. Aside from these iconic gems, any Golconda diamond in existence today has a legacy that outshines any other precious aristocratic heirloom. But quality and quantity rarely go hand-in-hand. After centuries of zealous mining for these natural wonders, by the late 19th century the Golconda mines were exhausted of their treasures. Many of the stones that originated from the region have long since vanished without a trace.

The Golconda diamonds that remain on the market are not only centuries old; they are exceptionally, vanishingly rare. Most people will only ever see a Golconda diamond in a museum. To own one is to own a piece of history; a physical connection to the Mughal Empire and the treasures of the nobility of past generations.

No connoisseur’s collection is complete without an incomparably beautiful Golconda diamond. As gem enthusiasts the world over vie to add these historic, unique stones to their collections, they will only become even more scarce, cherished and valuable.
