What colors are available besides classic blue?
While vibrant blue is most common, kyanite also occurs in green, orange, black, and clear varieties.
Can kyanite crystals be faceted into gemstones?
Transparent kyanite can be faceted into rare collector gems, requiring precise orientation due to its variable directional hardness.
