Fluorite Crystals

About

Searching for a specific fluorite specimen? Rare locality pieces, display slabs, matched sets. Submit a sourcing request → Fluorite. Known for its extraordinary color range, sometimes showing green, purple, blue, and clear banding in a single piece. The geometry of natural fluorite octahedrons is some of the most satisfying in the mineral world. Collectors love this one. Fluorite — The Most Colorful Mineral Fluorite (calcium fluoride, CaF2) occurs in virtually every color of the spectrum. Its perfect octahedral cleavage and wide color range — from deep purple and emerald green to golden yellow and clear — make it one of the most sought-after collector minerals. The best specimens come from China, Mexico, England, and the Illinois-Kentucky fluorspar district. Why does fluorite come in so many colors? Fluorite's color comes from trace impurities and radiation-induced color centers within the crystal lattice. Different conditions during formation produce different colors, often within the same crystal — creating the banded, rainbow specimens that collectors prize. Is fluorite fragile? Fluorite has a Mohs hardness of 4 and perfect octahedral cleavage, making it softer and more delicate than quartz. Display fluorite away from high-traffic areas and handle with care. It's a display mineral, not a wear-daily stone. Related Guides What Crystal Should I Wear?
