Blue Kyanite natural crystal blade 2 3/8" long, 5/8" wide. This large natural kyanite blade is from Brazil. Kyanite is said to enhance and balance your communication skills. It's a super throat chakra stone! Placing the kyanite on the body is said to clear, align and activate the charkas. Kyanite never takes on negativity., so it never needs cleansed. It works readily when placed at the throat chakra, approximately where the adam's apple would be. Carry it with you, meditate with it or put it to work at night remembering your dreams. I call it the lazy woman's way to meditate when I put the blade into my pillow case, far to the inside so it won't fall out when I go to sleep. Then i go to sleep. This affects my dreams causing me to remember them better. The total length is 2 3/8" long.
