ZinciteZincitePolandZincite, as a natural mineral, occurs in only one location: Franklin, New Jersey. The present, highly collectable zincite occurred "naturally" in the vent pipes of zinc smelters in Silesia (now called Poland). Known as a secondary mineral in mineralogical terms it is a "sublimate"—referring to its process of transformation directly from the gaseous, or fire state, to the solid state without ever becoming a liquid. A by-product of the smelting process, this classic source of "man-caused yet naturally occurring" zincite is now nearly exhausted. The present example is a strong reddish-orange stone, faceted as a cushion-cut, displaying excellent luster and clarity. Weighing approximately 9.01 carats and measuring 15.13 x 7.95 x 5.60mm None
