Diamond mining in India
The town of Karwan, near the fortress city of Golkonda, now a suburb of Hyderabad, became the world's largest diamond-cutting and diamond-trading center. Golconda was not close to diamond mines, but owed its status as a diamond center to its location on a major trade route from the mines to the south and east. The diamonds became known as Golconda Diamonds, and in Europe, the word Golconda came to mean a place of great wealth.
