Kyanite is a mineral found mainly in metamorphic rocks. It most often forms from the high-pressure alteration of clay minerals during the metamorphism of sedimentary rocks
Kyanite's typical habit is a bladed crystal, although it sometimes occurs as radiating masses of crystals.
Kyanite is a gemstone that you will rarely encounter in the typical jewellery store. Most people have not heard of kyanite, as it is infrequently used in jewellery. It is an "exotic" gem. Perhaps that is what makes it so interesting?
If you are interested in kyanite as a gemstone or in jewellery, the best place to find it is in artisan jewellery stores or in jewellery stores that are associated with a mineral dealer
High-quality and nicely coloured kyanite can be cut into attractive and desirable cabochons and faceted stones. These are often used in rings, earrings, pendants, and other jewellery. Kyanite is also used to make beads. These beads often have a flat geometry because the mineral typically occurs in thin blades.
Most gemstone-quality kyanite is blue in colour. However, kyanite can be clear, green, black, and rarely purple.
