Physical properties
Hardness 6.5-7 on Mohs scale, highly polished luster, cryptocrystalline quartz structure, conchoidal fracture
Formation & geological history
Formed in cavities of volcanic rocks as silica-rich fluids cooled over time. Artificial dyeing process adds the unnatural green color.
Uses & applications
Used in jewelry making, ornamental carvings, and collecting. This piece has a hole drilled for a pendant.
Geological facts
Agate is frequently dyed to enhance or change its natural colors. The bright green section in this specimen is artificially colored, while the dark brown/black section may be natural or also enhanced.
Field identification & locations
Identified by its banding patterns and often unnatural, very bright colors which indicate dyeing. Natural agates are found worldwide in areas with past volcanic activity.
