Rainbow Fluorite is a mineral from the Halides family which is comprised of calcium and Fluoride in a composition that is chemically formularized as CaF2. It is a beautiful gemstone naturally available in a rainbow of colors, a quality from which it acquired its name. With an isometric-hexoctahedral geometric system, this gemstone displays amazing color varieties of purple, green, yellow, blue and others. Internally, it can also have a thin film of Pyrite. It forms in granite and other kinds of igneous rock as a massive or granular substance with well-developed coarse crystals. The flat surface fractures in an irregular or uneven pattern.
Rainbow Fluorite has a perfect cleavage in each of the 4 angles giving rise to octahedrons. It is moderately strong having a hardness of 4 on the Mohs scale and a specific gravity of 3.1. It has a glassy luster with a refractive index of 1.434-1434. Displaying a weak fire value dispersion of 0.007, Flourspar, as it is also called, has no optic character and sign, and it does not manifest any pleochroic effect when turned to a different angle. Rainbow Fluorite stands out from other gemstones with its average density of 3.13 and transparent to sub-translucent diaphaneity. This gemstone is banded with fair stability and poor toughness.
