Fluorite makes a beautiful gemstone that comes in all colors, and can often be multicolored with two or more contrasting color within the same gemstone. Multicolored Fluorite gemstones often show banding patterns. Large and flawless crystals are fairly common, and these can produce very large and totally clear gemstones. However, due to Fluorite"s very low hardness and perfect cleavage, it cannot be used as a mainstream gemstone, and it is generally cut specifically for specialty collectors.
