Fluorite from the La Barre mine, Saint-Jacques-d'Ambur, Puy-de-Dôme, Auvergne-Rhône-Alpes, France is known the world over for its amazing colour zoning. This thumbnail specimen displays staggering zonation from amber, purple, blue and colourless, accentuated by the stepped shape of the crystal. The rear of the crystal shows significant damage, but the main front face of the Fluorite is lovely and glassy, with just the lower corner missing and one small chip on one edge. The front is dominated by an amber centre surrounded by a purple band and outer colourless zone. From the sides the purple layer appears much bluer. A small area of bladed Baryte crosses through the back and side of the crystal. A small, but dramatic Fluorite.
