Highly prismatic and extremely unusual, this Calcite from the historic St Andreasberg has a lot going for it. Rising up from the pinacoid base, the sharp, hexagonal prism alters to a tapering steeple that looks like it belongs on top of a church. The luster is glassy, the crystal primarily gemmy, and the fluorescence a reddish orange. Mined in the 1800's, this is a wonderful, unusual, and aesthetic thumbnail. I have not seen a Calcite crystal from St Andreasberg quite like this. Or anywhere else, for that matter. Kay's label indicates that she knew of the find, and that it is from the 1800s (19th century find with antique mounting). She further describes it as a "rare prismatic crystal with decreasing width."
