Smithsonite: The mineral smithsonite information and pictures

Smithsonite occurs in a wide variation of colors. Its typical globular habit and often vibrant colors make this a desirable mineral for collectors. Smithsonite is composed of zinc carbonate, but the zinc may be partially replaced with other elements. Those elements are responsible for the color variations.

Smithsonite - Wikipedia

Smithsonite, also known as turkey fat or zinc spar, is zinc carbonate (Zn C O 3), a mineral ore of zinc.Historically, smithsonite was identified with hemimorphite before it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion. The distinct mineral smithsonite was named in 1832 ...
