Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vibrant blue color from artificial treatment, waxy to vitreous luster, and microcrystalline trigonal structure.
Formation & geological history
Formed in cavities of volcanic and metamorphic rocks through the deposition of silica-rich groundwater, later artificially tumbled and dyed.
Uses & applications
Commonly used in jewelry, decorative items, and metaphysical crystal collections.
Geological facts
Natural blue agate is extremely rare, so vibrant blue stones on the market are almost universally common gray agate that has been artificially dyed.
Field identification & locations
Identified by its conchoidal fracture and waxy luster, though the unnatural bright blue hue immediately indicates artificial enhancement.
