Diamond mining in India
Diamonds were first recognized and mined in central India, where significant alluvial deposits of the stone could then be found along the rivers Penner ,Krishna and Godavari.
It is unclear when diamonds were first mined in India, although estimated to be at least 5,000 years ago. India remained the world’s only source of diamonds until the discovery of diamonds in Brazil in the 18th century.Golconda served as an important centre for diamonds in central India Diamonds then were exported to other parts of the world, including Europe.
Early references to diamonds in India come from Sanskrit texts .The Arthashastra of Kautilya mentions diamond trade in India.Buddhist works dating from the 4th century BCE mention it as a well-known and precious stone but don’t mention the details of diamond cutting. Another Indian description written at the beginning of the 3rd century describes strength, regularity, brilliance, ability to scratch metals, and good refractive properties as the desirable qualities of a diamond. A Chinese work from the 3rd century BCE mentions: “Foreigners wear it [diamond] in the belief that it can ward off evil influences”.
The Chinese, who did not find diamonds in their country, initially used diamonds as a “jade cutting knife” instead of as a jewel
