Historical Accounts of Golconda Diamonds

• The French merchant Jean-Baptiste Tavernier (1605-89) wrote that diamond mining in the Golconda district grew at an explosive rate in the mid-17th century. At the Kollur mine, 60,000 diggers and washers were employed.
• The French traveller Jean de Thévenot (1633-77) noted there was no uniformity in diamond prices and the king established a monopoly in mining.
• The French Catholic physician Gabriel Dellon, who traveled to India in the late 1660s, noted that the Surat is a place of great commerce; diamonds are brought there out of the Kingdom of Golconda.
