Mercury Diamond — a leading diamond pricing consultancy, decided to develop a tool that will aid them in valuation of rough diamonds according to company's logic. That's how our Rough Diamonds Price Lists system has been born, using known prices of polished diamonds available on the highly trusted sources in the internet, taking into account diamond mine production statistical data — size, color and clarity distribution, to name a few — and several modifiers such as salability factor discount, our solution produces a large variety of price-lists, according to the company's understanding of the market's "real prices", for rough diamonds from different origin, such as Angola, Congo, Russia, South-Africa or where the diamonds were recovered. Then, these price-lists would serve different needs of the rough diamond trading organizations from all around the world.
