Physical properties
Mohs hardness of 3, pale blue color, vitreous to pearly luster, and rhombohedral cleavage with specific gravity around 2.71.
Formation & geological history
Formed in sedimentary, metamorphic, and hydrothermal environments through the precipitation of calcium carbonate from aqueous solutions.
Uses & applications
Primarily used in decorative items, lapidary arts, and crystal collections due to its soothing appearance.
Geological facts
Calcite exhibits strong birefringence, meaning it splits light into two separate rays to produce a double image effect.
Field identification & locations
Easily identified by its soft hardness (scratched by a copper coin) and vigorous fizzing reaction when exposed to dilute hydrochloric acid.
