    Réf: M18a
    Colorless and clear rhombohedral variety of calcite exhibiting extremely marked birefringence. Used for manufacturing optical instruments. Minimum size: 2.5 x 2 x 1.5 cm. If you place the crystal above a dot, you will see 2 dots; if you rotate the crystal above the dot, you will then see one dot rotate around the other. This phenomenon is called the extraordinary ray; the other dot is called the ordinary ray.

    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.
