Purple fluorite is a natural and unusual opaque material and is new to Dakota Stones. We have not seen this specific material or the beads before and were only able to acquire a small batch of rough to cut into a select few rounds.
Mined in Russia, it differs from the more common transparent purple tones you normally find within banded fluorite. The colors range from a deep purple to a softer opaque pastel tone.
Green fluorite and quartz combine to create an interesting effect where the green color looks almost phosphorescent and the quartz remains transparent. Our lapidary artists cut many of the beads to have both distinctly quartz and distinctly fluorite parts. Dakota Stones only acquired a small batch of this material to cut into rounds, so the supply is limited.
More common fluorite is mined in China, Germany or the United States and is a colorful mineral that lends itself to ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals. Optically clear transparent fluorite lenses have low dispersion, so lenses made from it exhibit less chromatic aberration, making them valuable in microscopes and telescopes. Fluorite optics are also usable in the far-ultraviolet range where conventional glasses are too absorbent for use.
