Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vitreous to waxy luster, microcrystalline structure with conchoidal fracture, and specific gravity around 2.65.
Formation & geological history
Formed through the deposition of silica from groundwater in the cavities of igneous and sedimentary rocks over millions of years.
Uses & applications
Widely used for ornamental bead strands, jewelry making, and carved decorative items.
Geological facts
Many commercial red agate beads are artificially dyed or heat-treated chalcedony to enhance the vibrant red color.
Field identification & locations
Identified by its microcrystalline waxy texture and characteristic rounded bead shaping, commonly found globally in silica-rich volcanic deposits.
