There once was a time when India was the only place in the world where diamonds could be found. Beginning more than 2,000 years ago, in the current state of Hyderabad, diamonds were first excavated in the heavily fortified kingdom of Golconda. It is from these mines that the most famous diamonds, including the Hope and Koh-I-Noor, originated. Today, the exceptionally rare handful of jewels determined to be Golcondas are the most coveted diamonds in the world.

But why? What makes Golconda diamonds so special that they command a premium of 50% or more than that of a D-color diamond from any other locale? It all has to do with color. More accurately, their value lies in their amazing lack of color.

Golconda diamonds are graded as Type IIa, which means that the stone is totally void of nitrogen. Nitrogen is the element that gives diamonds a yellowish tinge. Without it, the stone is able to transmit UV and visible light that other diamonds block, making Golcondas so incredibly pure and transparent that they actually appear to be two to three shades whiter than any other D-color diamonds.  

Today, it is estimated that fewer than 2% of all the diamonds mined throughout the world can be graded as Golcondas. They are so rare, in fact, that most jewelers and gemologists can go their entire careers without even seeing one in person.

In India, Golconda diamonds were enveloped in magic and mysticism. The gems were believed to embody the powers of the gods, granting the owner limitless wealth, prosperity and power, so much so that only kings and high priests were allowed to possess them. Though we know that a Golconda diamond won’t grant your every desire, there is no denying their breathtaking beauty.  Elusive, exotic and captivating in every way, there’s no question why Golcondas are accurately referred to as the ultimate diamond.
