Description
Naturally occurring translucent orange to red color mineral of Zinc oxide that contains traces of Manganese. Large quantities of zincite have been found in Poland, Italy (Tuscany), Spain, Germany (Saxony), Tasmania and the U.S. (New Jersey). Deep red zincite stones obtained in New Jersey are sometimes cut into gems for costume jewelry. Fluorescent zinc glass is prepared with crushed zincite.
