Physical properties
Mohs hardness 6.5–7; vitreous to waxy luster; trigonal microcrystalline structure; artificially dyed bright magenta-pink with subtle crackle/banded patterns.
Formation & geological history
Formed as chalcedony precipitated from silica-rich groundwater inside volcanic cavities, then artificially heat-treated, fractured, and dyed.
Uses & applications
Commonly carved, tumbled, or drilled into beads and donuts for costume jewelry, decorative crafts, and metaphysical stones.
Geological facts
Agate's natural microscopic porosity allows it to readily absorb chemical dyes, a treatment practice that dates back to ancient Rome.
Field identification & locations
Identified by its waxy-to-vitreous sheen, conchoidal fracture, and unnatural concentrated dye along microfractures. Natural chalcedony is sourced globally, notably in Brazil and Uruguay.
