Kyanite stands out as a highly desirable blue mineral, often displaying deep, vivid blue tones or varied color zoning within a single crystal. Its distinctive coloration, along with well-formed and occasionally sizable crystal structures, renders it valued by both amateur and professional mineral collectors.

Kyanite defies expectations with its striking anisotropy, boasting different hardness levels depending on the angle, making it the most famous mineral for this unique trait. Its vertical hardness spans 4.5 to 5.5, while horizontally it toughens up to 6 to 7. Named after the Greek word "kyanos," meaning deep blue, Kyanite boldly flaunts its signature vibrant color.
