"WebThis is called cleavage. Cleavage occurs on planes that depend on the mineral’s crystal structure and where the mineral has weak bonds holding the atoms together. Minerals tend to break at these points of weakness. A mineral can have multiple cleavage planes. When you look at a mineral, usually the shape is defined by the cleavage planes. " - Cleavage mineral
