Golconda! What a name to utter in the world of diamonds! The word itself conjures up images of fabulous riches and wealth, bejewelled princes and horses, turbaned traders and covered oriental bazaars. But it is the dazzling diamonds for which the city is most renowned, having yielded some of history's greatest stones including the Agra, the Hope and the Koh-i-Noor. Located in the southern princely state of Hyderabad, the Indian diamond fields are scattered throughout a broad belt of ancient rocks extending nearly one thousand miles in the north-south direction along the eastern half of the country. The vast majority of the diamonds found were from alluvial deposits uncovered in five distinct districts, each separated by high terrain. Each district had its own name, the most famous being Golconda. The celebrated French gem-merchant, Jean-Baptiste Tavernier, who frequented India on numerous visits in the 17th century described Golconda diamonds as "pools of crystal water", a reference to the clear transparency and soft luminescent quality that is particular to these rarities. The Golconda mines were depleted by the mid eighteenth-century and diamonds of this famed provenance and distinction are seldom encountered today.
