Herkimer Diamond: crystal

This small Herkimer Diamond crystal has two visible terminations, one of which has some pitting from groundmass, the other of which shows key indentations suggesting that it was once part of a cluster. Other than one key, the sides and faces are clean, and there is a good clarity along with some black anthraxolite deposits and inclusions.
