About Calcite
Calcium carbonate, a very common mineral found in a vast array of colors and forms, known for its perfect rhombohedral cleavage and double refraction (Iceland Spar). It's an energy amplifier and cleanser, with specific colors resonating with different chakras and properties.

Geological & Scientific Details
Calcite is classified as a carbonate mineral mineral which typically crystallizes in the trigonal system. Its chemical formula is CaCO3. Common crystal habits include botryoidal, concretionary, druse, globular, granular, massive, rhombohedral, scalenohedral, stalactitic.
