Blue Fluorite with display card

Blue Fluorite with display card (shop SKU WJBFR39) is offered as a crystal 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.

It comes with a display card. 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.

• SKU: WJBFR39
