Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites & sedimentary rock. It is the high pressure polymorph of andalusite & sillimanite, & the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust. Kyanite is also known as disthene or cyanite.[5] Kyanite is strongly anisotropic, in that its hardness varies depending on its crystallographic direction. in kyanite, this anisotropism can be considered an identifying characteristic, along with its characteristic blue color. Its name comes from the same origin as that of the color cyan, being derived from the Ancient Greek word κύανος. This is generally rendered into English as kyanos or kuanos & means "dark blue". Kyanite is used as a raw material in the manufacture of ceramics & abrasives, & it is an important index mineral used by geologists to trace metamorphic zones.
