Dyed Agate
SiO2 (Silicon Dioxide)
AI-generated identification · may be incorrectHardness 6.5-7 on Mohs scale, translucent to opaque, crystalline structure is cryptocrystalline. The bright green color is likely artificial (dyed) given the vibrant, unnatural saturation often seen in commercial agate slices. Luster is vitreous to waxy.

Physical properties
Hardness 6.5-7 on Mohs scale, translucent to opaque, crystalline structure is cryptocrystalline. The bright green color is likely artificial (dyed) given the vibrant, unnatural saturation often seen in commercial agate slices. Luster is vitreous to waxy.
Formation & geological history
Agates form primarily in volcanic and metamorphic rocks. Silica-rich fluids fill cavities in the host rock over millions of years, depositing layers of microcrystalline quartz. The coloring in this piece was likely added post-mining.
Uses & applications
Used primarily in jewelry, decorative items, and lapidary arts. This piece is shaped and drilled for use as a pendant or similar jewelry component.
Geological facts
Agate has been used for hardstone carving since antiquity. The practice of dyeing agates to enhance or change their color has been common since Roman times.
Field identification & locations
Identified by its waxy luster, translucency, and hardness. The artificially bright green color is a key indicator of dyeing. Highly common on the commercial market.
