KYANITE

The name, KYANITE, is from the Greek "kyanos" meaning blue. It is an aluminum silicate and is a metamorphic mineral. Kyanite is a polymorph with two other minerals: andalusite and sillimanite. (A polymorph is a mineral that shares the same chemistry with another mineral, but that has a different crystal structure).


The mineral forms blue fibrous blade-like crystals, often with a darker blue color near the center and a lighter color towards the outer edges of the blades.


Kyanite is a beautiful gemstone when faceted, but it is difficult to process as it has two different hardnesses depending upon direction. Parallel to the length of the crystal, kyanite has a hardness of 5. At right angles to this direction it is 7.
