Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. Over 800 forms of calcite crystals have been identified. It occurs in diverse crystal shapes and colors. Calcite is the primary mineral component found in cave formations. Most common color of calcite is white but it can manifest in almost every color imaginable depending on what impurities the mineral is charged with. Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Cave Calcite (specifically) is formed out of aragonite crystals. Calcite and aragonite are both carbonates with the same exact chemistry. The difference is in their crystal structure and symmetries. They are the most common minerals to form cave structures like stalactites and stalagmites.
Calcite has more uses than almost any other mineral on earth. It is the principal constituent of limestone and marble and makes up a significant portion of the Earth’s crust. It is used in construction materials, abrasive, agricultural soil treatment, pigment, along with pharmaceuticals and other health and dietary applications.
Calcite is believed to be a powerful amplifier and cleanser of energy. Having the presence of Calcite in a room it will lower negative energy and enhance positive energy levels. Calcite is said to be an active crystal that speeds up development and growth physically, mentally and spiritually. Calcite is a spiritual stone that facilitates the opening of higher consciousness and psychic abilities.
