Kyanite is one of nature’s most striking blue minerals, often displaying intense shades of blue or even multiple hues within a single crystal due to color zoning. Its vibrant color, combined with well-formed and sometimes large crystals, makes Kyanite highly prized by both novice and expert collectors.

Kyanite is also strongly anisotropic, meaning its hardness varies depending on the direction of measurement. It is the most well-known anisotropic mineral, with a vertical hardness ranging from 4.5 to 5.5 and a horizontal hardness from 6 to 7. The name Kyanite is derived from the Greek word kyanos, meaning “deep blue,” reflecting the typical coloration of this beautiful mineral.
