About kornerupine
Kornerupine is a rare borosilicate mineral that occurs in green, brown, yellow, and blue-green hues, often with strong pleochroism. It has orthorhombic symmetry, Mohs hardness around 6.5–7 and good toughness when free of fractures, making it suitable for jewelry in principle, though its rarity keeps it largely in the collector realm.
