Red velvet calcite forms through the precipitation of calcium carbonate from mineral-rich solutions in geological environments such as caves, hot springs, and hydrothermal veins. The presence of impurities like iron or manganese during the formation process imparts the red coloration to the calcite crystals.
Calcite is one of the most abundant minerals on Earth and can be found in a variety of geological environments: Mexico for their sedimentary deposits (limestone), certain areas in the US with metamorphic rocks (marble), and as secondary minerals in igneous rocks.
Calcite is relatively soft and has perfect cleavage, so it requires careful handling to avoid damage. Notable red velvet calcite specimens often feature well-formed crystal clusters with deep red to burgundy hues.
