Nekrasovite

Nekrasovite is a rare copper vanadium sulfosalt mineral with formula Cu26V2(Sn,As,Sb)6S32. It crystallizes in the isometric system and occurs as small grains in ore aggregates. It is a brown opaque metallic mineral with Mohs hardness of 4.5 and a specific gravity of 4.62. It was first described in 1984 in the Khayragatsch ore deposit of eastern Uzbekistan and named for Russian mineralogist (born 1929).
