Schalenblende Small Slabs, One Side Polished - 1 Piece
These unusual specimens hail from Poland. They are a combination of galena (the silvery metallic part), sphalerite (the brown bands), and wurzite (the tan/vanilla color) which fluoresces orange under ultraviolet light. Some also contain a little pyrite. They occur in masses with concentric layers of the three or sometimes four minerals. Schalenblende is the German name which has carried over directly into English, although they are also called "brunckite" in Australia. Although mined in several European locations, this stone is less well known in the USA and correspondingly more rare.
Some pieces have a flat saw-cut on the backside, others still show their rough/raw state in back. Some would make great cabs for the adventurous lapidary! All make nice specimens, especially at the price!
All are about the same size, at 1 1/4 to 1 3/4 inches long and about 1 - 1 1/4 inches wide. The saw-cut ones are about about 1/3 to almost 1/2" thick.
