Physical properties
Hardness of 3.5 to 4 on the Mohs scale, yellow to brown color, vitreous to resinous luster, orthorhombic crystal system, and distinct cleavage in one direction.
Formation & geological history
Formed in low-temperature hydrothermal environments, caves as stalactites, or by precipitation from marine and freshwater springs.
Uses & applications
Used primarily in mineral collections, decorative carvings, and metaphysical practices.
Geological facts
Aragonite is a polymorph of calcite, meaning it shares the same chemical formula but has a different crystal structure and is less thermodynamically stable at surface conditions.
Field identification & locations
Identified by its characteristic orthorhombic prismatic crystals, effervescence in dilute hydrochloric acid, and lower stability compared to calcite.
