A terminated, unusually sharp Painite crystal from the type locality of this rare specie. This crystal has bright luster, some transparency / translucence and red highlights under strong lighting. Far better than typical for this usually crude mineral. For many years Painite was described as the worlds rarest gemstone., at that time a crystal of this quality would be priced in the mid 4 figures when available. That has changed over the past decade but this is still certainly a rare mineral. Although dark this is not etched, included or cracked and could certainly be faceted.
