Estimated value of the rock — $ 70 million. He was found in November 2015 at the Botswana Diamond company Lucara. In size it is inferior only to the diamond "Cullinan" ("the Star of Africa) weighing 3106 carats (621,35 grams), produced in 1905 and presented to king Edward VII. But since the "Cullinan" was split when cut into nine pieces, "Our light" is currently the largest gem-quality diamonds in the world.
