Quartz Fluorite Pyrite Cluster

Quartz Fluorite Pyrite Cluster is a crystal cluster (shop SKU QUPYFL3) on the shelves at Namaste Bookshop in Manhattan.

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.

A cluster is a group of crystals that grew together; no two have the same arrangement of points. 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.
