It refers to different hardness. It shows one of the biggest characteristics of kyanite, 그게, the product is in different directions on the same crystal. The hardness of the surface will vary greatly. The hardness of the crystal surface in one direction is 4.0-5.0, and the hardness of the crystal surface perpendicular to it is 6.55-7.0. This is because the mineral crystals are in different directions. It is caused by differences in internal structure, and this difference makes it known as the “two hard stones”.

Kyanite is a rare oxygen-containing salt silicate mineral. Its chemical composition is the same as that of andalusite and sillimanite.
