Rare minerals

It is a sulfide of the linnaeite group. The color ranges from copper to metallic gray. It appears at the beginning of the metasomatism of copper deposits consisting mainly of sulfides. Carrollite is a rare copper-cobalt-nickel sulfide. Hardness 4.5 to 5.5. Chemical formula: Cu(Co,Ni)2S4. Density: 4.65. Luster: metallic. Cubic system, the fracture is conchoidal, crystals can be octahedral, rhombododecahedral, cuboctahedral, or cubic. ... info ... mode=
