Physical properties
Hardness of 6.5-7 on the Mohs scale, vitreous to waxy luster, microcrystalline quartz structure, and vibrant blue coloration resulting from artificial dying.
Formation & geological history
Formed by the deposition of silica from groundwater in cavities of igneous and sedimentary rocks, subsequently tumbled and artificially dyed by humans.
Uses & applications
Widely used in jewelry, ornamental carvings, metaphysical practices, and as tumbled decorative stones.
Geological facts
Natural agates rarely occur in bright blue; most vibrant blue specimens on the market are quartz or chalcedony that has been artificially dyed.
Field identification & locations
Identified by its microcrystalline texture and conchoidal fracture, though unnatural, saturated color bleeding indicates artificial treatment.
