Physical properties

Formation & geological history

Formed in sedimentary environments through chemical precipitation or as a primary mineral in igneous and metamorphic rocks. Often found in hydrothermal veins and hot springs.

Uses & applications

Industrial use in cement and lime production, as an acid neutralizer, and as decorative stone or carvings for energy work and crystal collections.

Geological facts

Calcite is known for its property of double refraction (birefringence), where light passing through it is split into two rays. Yellow calcite is specifically associated with the 'solar plexus chakra' in metaphysical practices.

Field identification & locations

Identified in the field by its softness (can be scratched by a copper coin) and its vigorous effervescence (bubbling) when exposed to weak acids like vinegar or diluted HCl. Common worldwide, especially in limestone-rich regions.
