Kyanite is polymorphous with sillimannite and andalusite. It is commonly pseudomorphed to andalusite. While kyanite is a relatively common mineral, good crystals are fairly rare. The best crystals have been found in pegmatites as well as quartz veins. Recently, Brazil has been a producer of fine specimens.
Kyanite is a challenging mineral to cut because it has two distinctly different hardnesses. Kyanite crystals are typically long, narrow blades. They have a hardness of about 4.5 parallel to their length but a hardness of 6.5 to 7.0 across the width of the blade. Skilled cutters are needed to work these stones.
