Poland
By AGTA Spectrum Award Winner Mark Kaufman
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 “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. Weighing approximately 28.16 carats and measuring 23.5 x 10.5 x 8.0 mm
