Kyanite ~ Learning Geology

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.

Kyanite | mineral | Britannica

Kyanite, also spelled cyanite, also called disthene, silicate mineral that is formed during the regional metamorphism of clay-rich sediments. It is an indicator of deep burial of a terrain. Kyanite occurs as elongated blades principally in gneisses and schists, and it is often accompanied by garnet, quartz, and mica.It can also occur in igneous rocks such as granite.

Kyanite and Related Minerals Statistics and Information

Kyanite, andalusite, and sillimanite are anhydrous aluminosilicate minerals that have the same chemical formula, Al2SiO5, but differ in crystal structure and physical properties. When calcined at high temperatures (around 1,350° C to 1,380° C for kyanite and slightly higher for andalusite and sillimanite), these minerals are converted to mullite, 3Al2O3·2SiO2, and silica,

Minerals: Optical and Physical Properties | Rocks | Geology

Optical Properties of Minerals: Such properties of a mineral which are related to the behaviour of light while being transmitted through or reflected from it are grouped under optical properties. They are of great significance in the determinative mineralogy and highly useful in identifying individual minerals occurring in very small, physically inconspicuous grain size, as for examples in rocks.
