Physical properties
Hardness: 7 on Mohs scale; Color: Deep pinkish-red (dyed); Luster: Vitreous to waxy; Crystal Structure: Trigonal/Microcrystalline; Cleavage: None, conchoidal fracture
Formation & geological history
Formed in volcanic cavities where silica-rich fluids precipitated over time. The specimen has been artificially dyed to achieve its intense reddish-magenta hue.
Uses & applications
Used extensively in fashion jewelry, cabochons, wire-wrapping, metaphysical practices, and decorative crafts.
Geological facts
Natural agate is typically gray, brown, or white. Dyes easily penetrate its porous microcrystalline structure, making bright pinks, purples, blues, and reds very common in commercial stone markets.
Field identification & locations
Identified by its high hardness, smooth polished texture, and unnatural intense uniform color concentrated in micro-fractures. Commonly found in Brazil, Madagascar, and Uruguay before processing.
