Epidote Peru

Among the books, decks, and stones on 14th Street is this crystal: Epidote Peru (shop SKU HEPD4).

Epidote is a calcium aluminum iron silicate, typically pistachio to dark green, and often forms slender prismatic crystals or compact masses. In crystal traditions, epidote is associated with release and with a sense of increase. Those ideas belong to folklore and personal practice, not to any medical claim.

Natural stones vary in color, clarity, and shape, so the piece you receive will have its own character even when the weight, grade, or size is listed. The title gives the origin as Peru.
