WebCleavage: In mineral terms, cleavage describes how a crystal breaks when subject to stress on a particular plane. If part of a crystal breaks due to stress and the broken piece retains a smooth plane or crystal shape, the mineral has cleavage. A mineral that never produces any crystallized fragments when broken off has no cleavage. WebPyrite FeS2 6-6.5 5 Dark grey Brass yellow; tarnishes brown. Cubes or octahedrons Brittle. No cleavage.
