Kyanite is one of nature’s most captivating blue minerals. It can display 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 valued by both novice and experienced collectors.

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