Crystallized minerals

It is indicated that the garnets are orange-brown to orange in color, but due to light reflection when taking the photo, the galena also appears to have this color, whereas it is metallic gray.

The crystal system is cubic. Crystals are cubes or octahedra, often twinned. The habit can be granular, massive, or compact. Perfect octahedral cleavage. Conchoidal fracture. It is often associated with quartz, calcite, dolomite, galena, pyrite, chalcopyrite, sphalerite, barite... Chemical formula: CaF2. Hardness: 4.

Photo from 2 different viewpoints. Erythrite: Cobalt ore. Chemical formula: Co3[AsO4]2.8H2O. Crystal system: monoclinic. Annabergite or nickel bloom. Arsenate group. System: Monoclinic. Density: d3.1. Chemical formula: Ni3[AsO4]2.2H2O. Appears as aggregates of lamellar crystals of apple-green color. This is a rare product of the alteration of nickel-bearing sulfides.
