Calcite is a form of calcium carbonate that occurs commonly in limestone and is low on hardness scale. Crystals are rhombohedral or hexagonal with vitreous luster. Globular, botryoidal, stalactitic, twining and other forms are also known. Cleavage is usually in three directions parallel to the rhombohedron form. Calcite is either colorless or white, gray, red, orange, yellow, green, blue, violet, brown, or even black depending on presence of impurities. It is transparent to opaque and may display phosphorescence or fluorescence due to presence of manganese and organic molecules. It exhibits retrograde solubility, i.e. low solubility at higher temperatures. Single calcite crystals display strong birefringence (double refraction) that make objects viewed through calcite to appear doubled.

Due to unique optical properties such as birefringence, calcite is used in optical equipment for navigation. Calcite is used as a scaffold in bone tissue engineering. It prevents release of phosphorus from sediments into the water, thus inhibiting cyanobacteria overgrowth. Trilobites, animals that lived 25 billion years ago had unique compound eyes with clear calcite lenses. The stone is used for making carvings and decorative objects. It is used in jewelry due to its range of different colors and optical properties. Calcite is believed to promote emotional healing and mental clarity. White (colorless) calcite is a common calcium carbonate mineral that occurs in the form of layered cubic crystals that are pearly/chalky white, as well as pale white and even light grey. Iceland Spar is a clear transparent variety of calcite. White Calcite is believed to unlock inner vision and bring clarity in vision. Yellow calcite is believed to encourage encourage self-confidence, optimism, and courage. Blue calcite is associated with communication and relaxation, and orange calcite with creativity and positivity. Green calcite is believed to support the immune system and promote physical healing. Calcite is also believed to amplify energy and strengthen intentions.
