Altered Kyanite crystals on matrix3D Model
Locality: Schneeberg, Germany
Size: 6.7 x 5.4 x 2.2 cm
Description: Kyanite is a mineral found mainly in metamorphic rocks. Kyanite specimens have a variable hardness. The long crystals have a Mohs hardness of about 4.5 to 5 if tested parallel to the length of a crystal, and a hardness of 6.5 to 7 if tested across the short dimension of a crystal. The mineral was once commonly called ‘disthene’ which means ‘two strengths’. It sometimes exhibits intense shades of blue, or even multiple shades with color zoning in a single crystal.
