The best gem-quality ruby crystals were extracted from the Dorkhan deposit in the lower zone of corundum mineralization. Pink, violet and almost colourless sapphire is less common than ruby. Corundum var: Ruby and Corundum var: Sapphire.(Ref: E.Ya. Kievlenko, Geology of gems, 2003, p. 55). In early '70s there was a special project of mining (gem stones) which wasat a standstill due to government action. Nowadays some young people mainly unemployed try to find some ruby and other precious gems in long tunnels approximately 1 km long.
