Physical properties

Formation & geological history

Forms primarily through sedimentary precipitation from calcium-rich solutions or in low-grade metamorphic environments such as marble veins. Often found in hydrothermal environments where calcium carbonate deposits from hot mineral waters.

Uses & applications

Popular among crystal collectors, used in gemstone carvings, lapidary arts, decorative objects, and metapsychological/healing applications.

Geological facts

Calcite is one of the most common minerals on Earth, but the soothing pale green color is less common and usually caused by trace amounts of chlorite or malachite during crystal formation. Like all calcite, it reacts vigorously with dilute hydrochloric acid.

Field identification & locations

Identified by its softness (can be scratched by a copper coin or steel knife), smooth waxy feel, light pale green color, and strong acid reaction. Major deposits are found in Mexico, Brazil, Pakistan, and the United States.
