Kyanite
Kyanite, whose name derives from the Greek word kuanos sometimes referred to as “kyanos”, meaning deep blue, is a typically blue silicate mineral, commonly found in aluminium-rich metamorphic pegmatites and/or sedimentary rock. Its color indeed can make it a lovely gem with a near sapphire-like blue. Usually its color is blue but also can be colorless, white, gray, green or yellow. Color is often not consistent throughout the crystal, often showing white streaks in a medium blue.
Kyanite is used primarily in refractory and ceramic products, including porcelain plumbing fixtures and dishware. It is also used in electronics, electrical insulators and abrasives. Kyanite has been used as a gemstone, though this use is limited by its anisotropism and perfect cleavage. Kyanite is one of the index minerals that are used to estimate the temperature, depth, and pressure at which a rock undergoes metamorphism.
Because kyanite is brittle in nature, it is seldom used in jewelry. Since hardness is related to the cut, kyanite is used best for earrings and pendants, which aren’t exposed to the stress a bracelet or ring could experience.
Kyanite opens and clears the body’s communication centers. For channeling or meditation purposes it works best when it is worn near the throat chakra. Kyanite never needs cleaned or charged because it is self-caring, self-sustaining. It carries a very “light” energy that attracts light beings. Wonderful manifesting stone.
