Physical properties
Hardness of 3.5 to 4 on the Mohs scale, typically white, yellow, or pinkish-brown, with a vitreous to resinous luster and distinct orthorhombic crystal structure.
Formation & geological history
Formed in low-temperature environments including marine settings, hot springs, and caves through the precipitation of calcium carbonate.
Uses & applications
Utilized in mineral collections, ornamental carvings, and holistic healing practices due to its attractive radiating crystal clusters.
Geological facts
Aragonite is chemically identical to calcite, but its orthorhombic crystal system makes it less stable and prone to converting to calcite over geological time.
Field identification & locations
Easily identified by its characteristic prismatic cluster habit and effervescence when tested with dilute hydrochloric acid; notable localities include Morocco, Spain, and Pakistan.
