Kayanite Crystal approx 100 grams.
Kyanite is one of the two minerals on the planet that neither accumulates nor retains negative energy, and therefore never needs cleansing. Kyanite's energy is unlimited in application, making it an excellent stone for metaphysical purposes, and it may be used for cleansing and clearing other crystals. This crystal is approx 100 grams. All kayanite that I have available is hard and cab be polished.
