Kyanite is an uncommon aluminosilicate mineral typically found in metamorphic rocks. Translucent shades of kyanite are blue, black, green, and orange. In rare occasions it forms beautiful transparent crystals prized as gemstones.

Physical Properties of Kyanite
Kyanite belongs to the triclinic crystal system, and has, and bladed crystal habit. The typical habit of kyanite is bladed crystal, although it can also appear in many radiating crystals. It is also found in fibrous and columnar forms. It is associated with metamorphic minerals, including staurolite, garnet, and corundum.

The name kyanite comes from the greek Kyanos which means deep blue. But this mineral has undergone a varied and rich naming process. At one point, Kyanite was named Disthen, meaning two strengths. This is because of the unusual property of having 2 different hardness measurements depending on which axis of the crystal is tested! Kyanite is much harder across the short axis of the crystal than along the long axis.

Kyanite Occurrence
Kyanite is found in metamorphic rocks like mica schists, biotite gneiss, and hornfels that have been under the extreme heat and pressure of continental collision. It comes from the alteration of sedimentary clay minerals.

Uses for Kyanites
Kyanite is used in making ceramics and porcelain, especially where heat resistance is a factor. It is also use as an insulator in electronics. It is a popular gemstone, but it is not found everywhere. Only artisan and specialty jewelry stores carry this exotic gem. They are challenging to cut. Kyanites have distinctly different hardness. They have a hardness of 6.5 to 7.0 across the blade width and 4.5 hardness parallel to their length. Therefore, experienced cutters are required to work with these gemstones. High-quality kyanites can be cut into attractive faceted stones and cabochons. They are also used for making rings, pendant earrings, and other jewelry.

Metaphysical Properties of Kyanites
While this mineral is known for inspiring logical thinking, it is also recommended for raising phychic abilities and connection with spirit guides, Kyanites can help clear negative energies.
