It is believed that diamond mining began in India during the 4th century BC. Diamonds were found in the eastern part of the country which was the only source of diamonds for about 2000 years, until new mines were discovered in Brazil in 1725 and then in South Africa in 1866.
However, it is the famous Golconda mines located within the realm of the Qutb Shahi Sultanate in the southern Deccan of India which were renowned to have produced the best quality diamonds. Most historic diamonds such as the Koh-i-Noor, now part of the crown jewels of England were probably discovered in this area in the 15th Century.
Golconda conjures up the mystery of India and the marvellous stories related to the city of Hyderabad. From the time of the ancient Rajas and Sultans to the reign of the Nizams, diamond mining activity enlivened the heart of the city.
Chemically pure, Golconda diamonds are limpid and have a very high degree of transparency and brillance, setting them apart from all other diamonds.
