Physical properties
Hardness 6.5-7 on the Mohs scale, brightly colored blue and white banding (due to dye), waxy luster, microcrystalline quartz structure.
Formation & geological history
Formed in volcanic rocks or ancient lavas where cavities are filled with silica-rich water. This specimen has been artificially dyed blue.
Uses & applications
Used in jewelry, decorative items, and lapidary arts.
Geological facts
Agates are very porous, making them easy to dye. The bright blue color seen here is not natural and is achieved through chemical dyeing processes.
Field identification & locations
Identify by its characteristic banding and waxy luster. Found worldwide, commonly in volcanic areas. Look out for artificially intense colors which indicate dyeing.
