3.7" Gemmy, Yellow, Cubic Fluorite Cluster w/ Calcite - Moscona Mine

This is an alluring, 3.7" wide, lustrous yellow fluorite crystal cluster that formed in association with sparkling pyrite and a flat, rhombohedral calcite crystal, collected from the Moscona Mine in Asturias, Spain. The fluorite crystals are translucent, fluorescent, and exhibit a beautiful yellow color. Under short-wave ultraviolet light, the fluorite crystals exhibit vibrant yellow-white fluorescence.

It comes with an acrylic display stand.

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 tend to be the most common colors seen, and colorless, pink, and black are the rarest.
