WebIn its crystal form, aragonite tends to have needlelike crystals and lacks calcite’s rhombohedral cleavage. In massive form, it is difficult to distinguish the two minerals in the field, as both react vigorously with cool dilute acid. Calcite is the more stable form and is far more abundant, and aragonite tends to convert to calcite over time.

WebCleavage planes are smooth, flat, parallel planes within the crystal. The cleavage planes may show as reflective surfaces on the crystal, as parallel cracks that penetrate into the crystal, or show on the edge or side of the crystal as a series of steps like rice terraces. WebCrystal faces can be flat, but remember they form as a mineral grows, while cleavage forms as a mineral breaks. The crystal form of quartz is a hexagonal prism, with nice flat sides.
