Green Purple Fluorite

This mineral specimen is listed as Green Purple Fluorite (shop SKU FLR225), and is sold at Namaste Bookshop near Union Square.

Fluorite is calcium fluoride; the purple variety is one of the most familiar colors. It is relatively soft. 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.
