Yttrium Fluorite is an unusual, rare and beautiful form of lavender Fluorite from Mexico. It is unusual in the fact that it does not cleave as other varieties of Fluorite and is extremely dense. Fluorite is known for being a mental body stone, but Yttrium is very different in the fact that it is attached to the physical world.

One of fluorite's more unusual properties is that it will fluoresce, or glow, under ultraviolet light. It was one of the first materials in which the phenomena of fluorescence was recognized and studied, and the term 'fluorescence' actually comes from the mineral name 'fluorite'. ^ Top.

Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. Fluorite is a colorful mineral, both in visible and ultraviolet light, and the stone has ornamental and lapidary uses.

The Moina skarn deposit, with its associated Sn-W-F veins and greisen, occurs at the margin of the Dolcoath leucogranite. The skarn occurs as a thick horizontal plate approximately one km in its longest dimension and up to 100 m thick and is separated from the granite's upper near-horizontal contact by approximately 200 m of the Moina sandstone.

University of Minnesota's Mineral Pages: Fluorite

Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.
