Physical properties
Mohs hardness of 3, yellow to honey-yellow color, vitreous to pearly luster, trigonal crystal system, and perfect rhombohedral cleavage.
Formation & geological history
Formed through the precipitation of calcium carbonate in sedimentary environments, hydrothermal veins, and hot springs.
Uses & applications
Used in optical applications, cement manufacturing, soil conditioning, and as a popular decorative or metaphysical specimen.
Geological facts
Yellow calcite exhibits strong strong birefringence, meaning it splits light into two separate rays to create a double image effect.
Field identification & locations
Easily identified by its distinct rhombohedral cleavage and strong effervescence when exposed to dilute hydrochloric acid.
