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.

Fan-like aggregates of pale blue tabular barite crystals on translucent blue fluorite make for an appealing display piece.
