About Raw Black Kyanite Crystals
Kyanite, also known as Disthene, derived its name from the Greek word for blue 'Kyanos'. Kyanite is one of the crystals that never needs cleaning as it doesn't retain negativity.
Black Kyanite is a great grounding crystal which can reduce stress, panic and negative thoughts. This crystal can be used to cleanse auras and is great to use whilst meditating.
Black Kyanite relates to the Base Chakra and is much rarer than Blue Kyanite!
