Pyrite Cube Spain

This crystal cube is listed as Pyrite Cube Spain (shop SKU LPCB15), and is sold at Namaste Bookshop near Union Square.

Pyrite, sometimes called fool's gold, is iron sulfide and often forms sharp cubes or glittering clusters. Peru is a well-known source. In crystal traditions, pyrite is associated with vitality and protection. 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.
