Russian miners at the Alrosa’s Udachnaya diamond mine pulled out a strange red and green stone out of the ground; they knew by instinct that they have something extraordinary. The red and green stone looked different from the thousands of tons of earth and ore they process each day. The workers had just unearthed a 30 mm rock which contained 30,000 diamonds. It was a rock which had diamonds in a concentration which was 1m times higher than normal.
In spite of the rarity of the discovery, the company donated the rock to the Russian Academy of Sciences, as the diamonds are so small that they cannot be used as gems. The rock was found in Russia’s Udachnaya diamond mine.
