Wonderful smithsonite sphere with stand. Smithsonite, also known as zinc spar, is a mineral that belongs to the carbonate mineral group. It is a secondary mineral that forms as a result of the weathering and oxidation of primary zinc ore deposits. Smithsonite typically occurs in a variety of colors, including green, blue, pink, yellow, and brown. The brown color in brown smithsonite can be attributed to different factors, such as the presence of iron oxides or hydroxides, manganese oxides, or other elements that can cause discoloration in the crystal lattice. It is a relatively soft mineral, with a hardness of 4 to 4.5 on the Mohs scale, making it susceptible to scratching.
