    Réf: M1058

    Congo

    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=

    Rare collection stone

    Natural stone, with its certificate of authenticity. In certain transparent minerals, colors and intensity vary according to direction. Dichroism is when the crystal shows two main colors, trichroism when there are three colors. The latter is only possible in rhombic, monoclinic, and triclinic systems. The term pleochroism applies to both phenomena. ... info ... mode=
