A rich reddish-orange color defines this beautiful stone. Zincite, 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 sublimatereferring 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. Of particularly large size for its type, this elongated, cushion-cut stone possesses the highest transparency and luster as well as a brilliant tangerine orange color and is suitable for collector of rarities.
