berzelianite
Sign in to saveBerzelianite is a rare copper selenide mineral with the formula Cu2Se. It occurs as thin dendritic crusts or as fine-grained inclusions. It crystallizes in the isometric system, unlike its dimorph, bellidoite, which crystallizes in the tetragonal system. The crystals are opaque and slightly malleable.

It crystallizes in the isometric system, unlike its dimorph, bellidoite, which crystallizes in the tetragonal system. The crystals are opaque and slightly malleable.
== Occurrence and name == Berzelianite was first identified at the Skrikerum Mine (also spelled as Skrickerum Mine) in Valdemarsvik, Östergötland, Sweden in 1850.
