Physical properties
Hardness of 6.5-7 on the Mohs scale, pink to white concentric bands, waxy to vitreous luster, and trigonal crystal system.
Formation & geological history
Formed through the deposition of silica-rich groundwater solutions in cavities of ancient volcanic or metamorphic rocks over millions of years.
Uses & applications
Widely used in ornamental carvings, jewelry, lapidary art, and cherished by mineral collectors.
Geological facts
Agate banding reflects successive pulses of fluid deposition and varying mineral impurities within a void. Ancient civilizations valued agates as protective talismans.
Field identification & locations
Identified by distinctive concentric color banding and waxy luster; commonly found worldwide in volcanic host rocks and river gravels.
