Smithsonite

SmithsoniteSmithsonite is a common natural zinc carbonate (ZnCO3), named after the famous English chemist and mineralogist James Smithson 1754-1829, who was the first to identify the new mineral composed of zinc ores.

A bright yellow variety, rich in cadmium is sometimes called “turkey ore.” Iron gives it a yellowish or brownish color (ferrosmithsonite). Spherulites are sometimes decorated with bright red inclusions of native copper. The mineral often fluoresces with green under UV light.

Smithsonite Smithsonite forms cryptocrystalline aggregates, spherulites, psevdo-stalactites or glassy crusts with banded coloring. Well-formed isometric crystals are rare. The mineral may be translucent to transparent; its hardness is 4.5-5.

Smithsonite is not considered to be a jewel, but thanks to a variety of bright colors, the mineral is sometimes used as a masonry product, and in jewelry.
