Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vibrant artificial blue color with natural concentric banding visible underneath, waxy to vitreous luster, and cryptocrystalline structure.
Formation & geological history
Formed by the deposition of silica from groundwater in cavities of igneous and sedimentary rocks, subsequently enhanced with artificial blue dye.
Uses & applications
Widely used in jewelry, ornamental carvings, and as a popular tumbled specimen for crystal collectors.
Geological facts
Agate is the banded variety of chalcedony and has been used for adornment and amulets since ancient times. The vibrant blue color is not naturally occurring and is achieved through chemical dying.
Field identification & locations
Identified by its distinctive eye-like ring patterns and intense unnatural blue coloration. Common worldwide but heavily processed commercially.
