    Golconda diamonds reign supreme among gem connnoisseurs around the world in terms of quality, mystery and romance.

    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, the famous Golconda mines located within the realm of the Qutb Shahi Sultanate in the southern Deccan of India 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.

    Universally esteemed as the finest diamonds, 'Golconda' diamonds appears to have a light softness making them gentle and stricking. Their superb luminousness and transparency sets them apart from all other diamonds.
