Kyanite is a semi precious stone. This is the most trending and demanding stone in recent days. People are using them for making jewelleries and other accessories.
Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite, and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust.
