Learn More About Fluorite Gemstone

What is Fluorite?

Fluorite is a beautiful, cubic shaped crystal that appears in a variety of colors, but most often in purple, green, blue and yellow. The purest Fluorite is actually colorless. However, the crystal’s impurities react in the strangest manner, causing the most amazing colors to appear, even earning it the reputation of being the ‘most colorful crystal in the world!’
 
The main component of Fluorite is Calcium Fluoride found mostly in the form of vein growths in rocks, it is widely used as an industrial mineral in the chemical and ceramic industries as it has a very low melting point. Further, superior quality Fluorite is one of the main elements in the manufacture of optical lenses for telescopes, microscopes and cameras.
 
Fluorospar is the name it is known by in these industries, whereas Fluorite is the gemological reference term.

Fluorite Energy
