What is Kyanite?
Kyanite or aluminum silicate is a bluish green to colorless mineral which is typically found in metamorphic rocks. This mineral is used commercially in the production of some ceramics, and it is also sometimes cut for use as a gemstone. The world’s major suppliers of kyanite are in the Ural Mountains, Italy, Switzerland, and the American Northeast; patches of the mineral can also be found in other deposits around the world. This mineral is classified among the aluminosilicate series, and it tends to turn up in locations which are rich in aluminum. It is also considered to be a polymorph of andalusite and sillimanite, meaning that these minerals share identical chemical structures, but their crystalline matrixes are different. Because the crystal formation is impacted by factors like heat and pressure, these minerals can sometimes be used as indicators of geologic history when they are found. Several things make kyanite distinctive. The first is the shape of the crystals, which tend to
