Also called Disthene, the name Kyanite is derived from the Greek “kyanos”, meaning blue. The most popular varieties display intensely beautiful colours reminiscent of top Ceylon and Kashmir Sapphires. Although the name Kyanite has been used since 1789, Kyanite was sold in Europe as Sapphire until the turn of the 20th century.
Legends and lore
The powerful blue hues of Kyanite have long been thought to inspire calmness, composure, serenity, loyalty and respect.
Kyanite is used by alternative healers as a tool for meditation and relaxation. These healers use Kyanite to open the third eye chakra to enhance creativity, broaden perception and to reach a better understanding of others. Kyanite is also said to foster tranquillity and believed to have a positive effect on dreams, visualization and foresightedness.
Just the facts
Kyanite has perfect cleavage in one direction, a unique characteristic among gemstones. This combined with its varying hardness (Kyanite is a rare polymorph, displaying two hardnesses within one gem), makes Kyanite a challenging gem to facet. Understandably, the cutting of Kyanite is an extremely important quality consideration.
Occurring in a wide variety of locations around the world, the best quality Kyanite hails from a deposit discovered in 1995 in the Kali Gandaki region of west central Nepal and Tibet. Tibetan Kyanite is arguably the best ever found, displaying rich cobalt blues, evocative of superb Sapphires.
