Zincite with Franklinite Franklin NJ


Zincite is the mineral form of zinc oxide (ZnO). In nature its crystal form is rare, with the exception of the Franklin and Sterling Hill Mines in New Jersey, an area also famed for its many fluorescent minerals. It has a hexagonal crystal structure and color that depends on impurities. The zincite found at Franklin Furnace is red-colored (mostly due to iron and manganese) and associated with willemite and franklinite. Zincite crystals can be grown artificially and synthetic zincite crystals are available as a by-product of zinc smelting. Synthetic crystals can be colorless or range in color from dark red, orange, yellow to light green.
