JULY 23 ![]() Russia's first underground diamond mine reached its predicted efficiency rate
Russia's first underground diamond mine "Internazionalny" reached its predicted efficiency rate. The mine belongs to the joint-stock company "Diamonds of Russia - Sakha" and is situated 17 kilometers from the city of Mirny. These diamond deposits annually allow to process up to 500 tons of ore and to produce diamonds worth around $300 million. According to RIA "Oreanda", the diamonds from "Internazionalny" mine are better that Australian or South African diamonds in terms of quality for jewellery manufacture and clarity.
