Physical properties
Hardness of 6.5 to 7 on the Mohs scale, yellow to translucent coloration, waxy to vitreous luster, microcrystalline quartz structure with no visible cleavage, and a specific gravity of 2.60 to 2.65.
Formation & geological history
Formed through the deposition of silica from groundwater in the cavities of igneous and sedimentary rocks, often developing over millions of years in concentric layers.
Uses & applications
Commonly used in jewelry, ornamental carvings, polished display pieces, and metaphysical collections.
Geological facts
Agate is a variety of chalcedony and has been used since ancient times for amulets, seals, and ornamentation due to its durability and attractive banding.
Field identification & locations
Identified by its translucency, conchoidal fracture, and smooth tumbled texture. Found worldwide in regions with volcanic activity and ancient riverbeds.
