What is Fluorite? 

Representing one of the widest color ranges of any mineral, fluorite’s hues tend to be vibrant, with violet, green, and yellow the most common. Its colors are commonly found as zones of different colors within a single crystal, and these zones typically follow the contour of the crystal faces. Fluorite is easily cleaved (broken along its atomic planes) and so is faceted for collectors only. For this, the stone is carefully oriented to avoid its four cleavage planes, and then cut and polished slowly to avoid heat or vibration.
