The Kyanite Bracelet Also known as disthene, rhaeticite and cyanite, Kyanite derived its name from the greek word, Kynos meaning deep blue. This stone possesses an exceptional magnetic force, hence it was used as a compass in ancient times. It is a blue aluminosilicate mineral found in Switzerland, Brazil, Russia, Kenya, Nepal, Tanzania and in the eastern United States. This stone depicts a very strange quality; the hardness of this stone varies with its direction. The brilliant blue color and the appearance makes it a great choice for curating 925 sterling silver jewelry with this.
