Golconda Diamonds: What Are They?
The Golconda diamond mines are located in south central India in what today is the state of Hyderabad. This region was the first known source for rough diamonds from approxiamtely the 4th century B.C. until 1730 when diamonds were discovered in Brazil.
The defining characteristics of Golconda diamonds and what sets them apart and in a class by themselves are their incredible transparency, "whiteness", and purity.
Both the Gemological Institute of America (GIA) and the world reknowned Gubelin Gem Lab characterize diamonds displaying the finest white color and transparency as type IIa, signifying that they are free from nitogen and are therefore chemically pure and colorless. The term "Golconda" has come to define diamonds of the finest white color and transparency.
Some descriptive terms used to define Golconda diamonds have been; "whiter than white", "like a clear river stream", and brighter than bright".
Golconda diamonds are very, very rare in today's market and if you do come across one it will usually be at a Christie's or Sotheby's auction.
