The blue disthene from Brazil is also called cyanite (kyanite) and due to its good cleavage disthene spar or sapphire spar. The hardness of the mineral depends on the direction - transverse to the crystal the Mohs hardness is 6 - 7, longitudinal to the crystal 4 - 4.5. With disthene rough stones the typical cornflower-blue color helps with the determination, as a cabochon disthene can be distinguished from other minerals only with the help of a mineralogical-gemmological examination.
In gemstone therapy, disthene is valued for its balancing effect; it brings resolute strength, but also serenity in complicated and confusing situations.
In jewelry making, the special properties of the stone must be taken into account - if the disthene is to be set as a cabochon in a pendant, for example, it must be stabilized beforehand, otherwise the stone would break.
