Kyanite is a semi-precious stone which is typically mined in a light blue shade. However, it could also be found in various other colors like white, gray, green, colorless and even almost black. This stone has a translucent to transparent look that is normally vitreous. It also possesses a bladed habit.

A unique attribute of kyanite would be the two different hardnesses it has. Many minerals just have a single hardness but there are some, like kyanite which actually have two. The hardness of a mineral is determined by its resistance to scratching which is demonstrated by that particular mineral. Kyanite's two hardnesses depend on the cleavage planes' direction in its internal structure.

Kyanite also has several interesting metaphysical properties. Some people believe that kyanite can actually enhance creativity, broaden perspective as well as assist in mutual understanding of an individual. It is often referred to as a stone of attunement. Many say that it could bring about calmness and tranquility as well as help in peaceful meditation.

It could also be helpful for the healing and treatment of various physical ailments, as it could clear up sinus congestion problems as well as enhance the treatment of numerous muscular disorders. It is one of the few stones which never need any cleansing or clearing. It could also assist in an individual's communication and mental awareness and helps in dream recall.

Because of the unusual hardness of kyanite, it does not have that much flexibility as a gemstone. It is usually polished smooth and set. However, it could also occasionally have facets cut on it.
