Arthur Androsov, Doctor of Engineering, Professor, a diamond industry veteran and inventor, gave this interview to Rough&Polished. 
Varda Shine, Managing Director of Diamond Trading Company (DTC), met our correspondent in London shortly before the World Diamond Congress in Moscow for this interview where she shared some of her views on the current state of affairs in the diamond industry.Reports say Tanzanite One has allayed fears that the country was running out of the precious blue mineral as only a very small fraction of the mining hills was being mined.
Tanzanite One general manager, Nick Hughes was quoted by Arusha Times as saying that the company’s geologists believed that there were more unexplored deposits of the rare blue gemstones deposits than the amount that is currently being produced.
“We are at the moment sinking a new mining shaft in addition to the four shafts currently in operation," Hughes was quoted as saying. “Most miners are not exploring for the future, they are simply mining for the present.”
Tanzanite mining area had expanded from the initial 8 sq km to 20 sq km, Arusha Times reports, adding that these were divided into four blocks.
Only Tanzanite One's block (Block C) had been explored by geologist.
The mineral reserves detected were estimated to be 2.2 million tonnes but ongoing studies are likely to discover even more deposits, it said.
"While it is not possible to find Tanzanite elsewhere in Tanzania, the geological composition at Mererani indicates abundant reserve of the rare blue gemstones it is just a matter of exploring more." Hughes was quoted as saying.
