Physical properties
Hardness 6.5-7 on the Mohs scale, vitreous luster, microcrystalline trigonal structure, featuring distinct crackled patterns often enhanced by artificial dying.

Formed by the deposition of silica from groundwater in cavities of igneous and sedimentary rocks over millions of years.
Uses & applications
Widely used in jewelry making, beadwork, and decorative ornamental items.
Geological facts
The crackled 'dragon vein' texture is typically created by rapidly heating natural agate and then quenching it in liquid.
Field identification & locations
Identified by its waxy-to-vitreous luster, conchoidal fracture, and web-like fracture patterns; found globally where chalcedony deposits occur.
