2.2" Lustrous, Yellow Cubic Fluorite and Barite on Quartz - Morocco

Lustrous, Yellow Cubic Fluorite and Barite on Quartz - Morocco #44904

This is a gorgeous specimen of bright yellow, cubic fluorite crystals on a quartz druse, from Meknes, Morocco. The crystals have sharp, well defined edges, glassy smooth faces, and interesting phantoms. Reddish-pink barite crystals protrude from between the fluorite cubes, although few stand perpendicular to the matrix. The entire cluster is 2.2x2.2" and the largest crystal is 0.35" wide.

Fluorite is a halide mineral comprised of calcium and fluorine, CaF2. The word fluorite is from the Latin fluo, which means to flow. In 1852 fluorite gave its name to the phenomenon known as fluorescence, or the property of fluorite to glow a different color depending upon the bandwidth of the ultraviolet light it is exposed to. Fluorite occurs commonly in cubic, octahedral, and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink, or black. Purples and greens are most commonly seen.
