Formed from calcium carbonate (CaCO₃), calcite is one of the most abundant and versatile minerals on Earth, often crystallizing in a wide variety of habits. This particular growth pattern highlights the dynamic conditions of its formation, where space, pressure, and mineral-rich fluids came together to create something truly one-of-a-kind.
