Physical properties
Hardness of 6.5-7 on the Mohs scale, waxy luster, microcrystalline crystal structure, conchoidal fracture, and distinct multicolored banding.
Formation & geological history
Formed by the deposition of silica from groundwater in cavities of igneous and sedimentary rocks over millions of years.
Uses & applications
Widely used in ornamental carvings, jewelry, decorative polished towers, and precision instruments due to its durability.
Geological facts
Agate is often associated with balancing emotional energy and has been used as a protective talisman since ancient civilizations.
Field identification & locations
Identified easily by its translucent banded patterns and hardness; commonly sourced from Brazil, India, and the USA.
