Kyanite is polymorphic, which means that it has two different degrees of hardness. The beautiful blue color of kyanite makes it very difficult to work with as a loose gemstone because it is very easily detached. It is attracting attention as a material for bead accessories not only because of its blue color, but also because of its rich colors and various shapes such as greenish and orange.
