Al Cerny Collection Al Cerny was a practicing mining engineer for over 30 years before retiring to South Carolina for the bass fishing. He worked at several mines including Sterling Hill near Franklin, New Jersey and the Northumberland Mine in Nevada where he was able to satisfy his collecting passion. Barite became his specialty, but the collection has far more than just barite.

This is the only “black” willemite in Al’s collection. A large single crystal dominates the specimen. The faces of the crystals are sharp, but the terminations are somewhat dull and not so sharp. This style has a subdued fluorescence unlike the blinding green of most willemite from here.
