Fluorite is a mineral that used to be used mainly for decorations. It is fairly soft so it can be easily carved. In recent times it also has industrial uses. Fluorite is used as a source of fluorine in hydrofluoric acid and fluorinated water. Fluorite comes in many colors. Fluorite crystals tend to be cube shaped.
These are very small pale yellow fluorite crystals that are cubic. Fluorite is often found in dolomitic limestone in Southern Ontario. Sphalerite, the dark brown gemmy crystals, is a mineral that is also often found in the same rock formations. SPECIMEN ORIGIN: Lafarge Quarry, Dundas, Ontario, CANADA
