3D ModelNoAI

Locality: Virgem da Lapa, Brasilia

Size: 2 x 1 x 0.5 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”.
