Physical properties
Hardness 6.5-7, multicolored (often dyed vibrant blue), vitreous luster, cryptocrystalline quartz.
Formation & geological history
Formed in cavities in eruptive rocks or ancient lavas. The bright blue coloration is usually the result of artificial dyeing.
Uses & applications
Used in jewelry, decorative items, and lapidary arts.
Geological facts
Agate is frequently dyed to produce vivid colors not commonly found in nature.
Field identification & locations
Identify by its waxy luster, banding or patterns, and hardness. Natural agate rarely has this neon blue hue.
