A sharp, very brilliant crystal of 7 mm stands out on a cluster of smaller crystals, all displayed dramatically on a natural pedestal of this ore/sulfide matrix. Sperrylite is a rare platinum-containing species that crystallizes in large and beautiful form. This crystal has superb luster and a brilliant shine to it in person. The main crystal here is remarkable for its symmetry and that all corners are on display. These came out mostly in the early 1990s to the market, though many were said to have been mined in the 1980s and stored in Russia's strategic reserves until released for sale.
