One of the more attractive Epidote specimens that I have seen, this piece consists of a cluster of thin, almost needle-like Epidote crystals that is partly intergrown with a hexagonal prismatic quartz crystal. These crystals range in length from 0.1 (3 mm) to nearly 2" (5 cm), but do not exceed 3 mm along either of their other axes. Many of them are damaged and incomplete, but those that are intact are easy to spot from light glinting off of their termination faces. Their monoclinic, prismatic form is excellent, and their terminations are well-formed, giving off a bright, vitreous luster. Their prism faces are striated and a bit duller, showing more of a pearly luster. Though some of the smaller, more exposed crystals show some noticeable transparence, their almost olive-green coloration is too deep to be even translucent in most cases. The intergrown quatrt crystal shows good hexagonal form, but its termination is completely enveloped by the Epidote cluster. Its other end its other end is slightly uneven but generally flat, and shows evidence of healing. It is colorless, transparent, and relatively clear, but 2 of its prism faces are very frosty, showing a matte luster; this makes it difficult to easily examine its interior. There is no evidence of any host rock.
