An extremely rare specimen from this locality, quite a bit more scarce than just about any style of apatite in fact... this is a really aesthetic, sharp, and bright cockscomb marcasite specimen! I had never seen one, so good, for sale. Not the most glamorous of a Panasqueira suite but still fairly desirable given the aesthetic sand rarity of such a piece which would complement the more common minerals in a collection of Panasqueira pieces. The pics do NOT do it justice...BETTER In PERSON
