Kyanite crystals on matrix

3D ModelNoAI

Locality: Lotru Mts., Romania

No.: 20246

Size: 15 x 9.5 x 6.5 cm

Formula: Al2(SiO4)O

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.
