SMITHONITE COBALTOAN
SMITHONITE COBALTOAN
SPECIMEN NR #:
Smithsonite, or zinc spar, is the mineral variant of zinc carbonate (ZnCO3). Initially, it was confused with hemimorphite until it was established that they are distinct minerals. Their similar appearances led to the use of the term calamine for both, causing some misunderstanding. The name smithsonite was given in 1832 by François Sulpice Beudant to honor the English scientist James Smithson, who first described the mineral in 1802.
This trigonal mineral exhibits a range of colors and is rarely found in well-formed crystals, typically appearing as earthy botryoidal masses. It has a Mohs hardness of 4.5 and a specific gravity ranging from 4.4 to 4.5.
THE ASSOCIATION WITH COBALT GIVES THE PINK HUE.
