Renowned jewellery historian and published author, Jack Ogden FGA, traces the history of Indian diamonds and questions the sustained marketing hype around the famous Golconda mines.
Today India is the largest centre for diamond cutting, handling some 90 percent of the world’s diamonds. But most who cut, sell or buy these diamonds, in the cutting centre of Surat or at the vast diamond exchange in Mumbai, are probably unaware that in the past the country was also the world’s major source of diamonds.
Exceptions are the dealers in larger stones, ones they hope a laboratory report might link to the famous Golconda mines in India, a link that allows a price premium.This article will look at India’s remarkable diamond history and ponder whether associating a diamond on the market with ‘Golconda’ is really just marketing hype.
