Golconda Diamonds: Mines, Legends and What Golconda Means Today
For centuries, the word "Golconda" meant diamonds. Some of the most famous gems in history are believed to have come from the Deccan region around Hyderabad, and the name still carries weight in the diamond world today. This article tells the story of Golconda diamonds and what the name means now.
The mines and the trade
The diamonds known as Golconda diamonds were not mined at Golconda itself. They came from alluvial deposits along the Krishna River basin in the Deccan, in what is now Andhra Pradesh and Telangana. The Kollur mines are among the best known.
Golconda, the fortified city just outside present-day Hyderabad, was the region's great trading centre. Under the Qutb Shahi dynasty, rough diamonds from the mines were brought to Golconda to be traded, cut and sold, and merchants and travellers from Europe and Asia came to buy them. So the stones took the name of the market, not the mine.
For a long time, India was the world's main source of diamonds. Over the centuries, the Deccan mines became exhausted, and new sources in Brazil and later Africa took their place.
Famous stones
Several of the world's most celebrated diamonds are believed to have come from the Golconda region, including the Koh-i-Noor, now among the British Crown Jewels, the Hope Diamond, held by the Smithsonian Institution, the Regent Diamond, displayed at the Louvre, and the Darya-i-Noor, in the Iranian crown jewels.
The histories of these stones are long and sometimes disputed, but they share a reputation for remarkable clarity and size.
Why Golconda is a quality term today
Today, "Golconda" is used in the diamond trade to describe diamonds of exceptional transparency, often colourless with an almost liquid clarity. Gemmologists associate many such historic stones with a rare type of diamond known as Type IIa, which contains little or no nitrogen. Laboratories such as the Gemological Institute of America (GIA) have written about this connection.
A modern diamond described as having "Golconda-like" quality does not necessarily come from the Deccan. The term refers to the look and character of the stone, not always its origin. If a diamond is described this way, ask what certification supports the description. Read The Diamond 4Cs for Indian Buyers and IGI vs GIA Certificates.
Diamonds in Hyderabad now
Hyderabad's diamond heritage lives on in its jewellery. The polki tradition, using uncut diamonds set in gold, reflects centuries of working with Deccan stones. Read Uncut Diamonds (Polki): How They Are Graded, Set and Priced.
At the same time, Hyderabad's jewellers work with modern cut diamonds, from everyday studs to solitaires. For the royal history of Hyderabad's jewellery, see Nizami Jewellery: A Short History of Hyderabad's Royal Style.
At Tibarumal & Sons Jewellers, Shaikpet, a family jewellery house since 1920, you can see both traditions: polki and uncut diamonds, and certified cut diamond jewellery.
