Physical properties
Hardness of 3.5 to 4 on the Mohs scale, typically orange, brown, or white, with a vitreous to resinous luster. It forms orthorhombic crystals, often exhibiting distinctive pseudo-hexagonal twinning.
Formation & geological history
Formed in low-temperature environments including marine settings, hot springs, and caves as stalactites or speleothems.
Uses & applications
Used primarily as a mineral specimen by collectors and occasionally in ornamental carvings or holistic wellness.
Geological facts
Aragonite is chemically identical to calcite, but its orthorhombic crystal system makes it less thermodynamically stable at surface conditions.
Field identification & locations
Identified by its characteristic prismatic crystal clusters and strong effervescence in dilute hydrochloric acid. Commonly sourced from Morocco, Spain, and Pakistan.
