Quartz Fluorite Pyrite

Quartz Fluorite Pyrite (shop SKU QUPYFL200) is offered as a mineral specimen online and at the bookshop on West 14th Street.

Fluorite is calcium fluoride and forms in cubes or octahedra, often in purple, green, or banded rainbow colors. It is relatively soft, so it is best handled gently. In crystal traditions, fluorite is associated with focus and clarity. 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 or grade is listed.
