Physical properties
Hardness: 6.5-7 (Mohs scale), Color: Black and dyed blue, Luster: Vitreous, Crystal structure: Cryptocrystalline, Cleavage: None, Specific gravity: 2.58-2.64
Formation & geological history
Formed from silica-rich fluids filling cavities in volcanic rocks, later artificially dyed to enhance color.
Uses & applications
Used primarily in jewelry, ornamental objects, and as a collector's item.
Geological facts
Agate is a variety of chalcedony. This particular piece has been carved into a heart shape and artificially dyed blue to enhance its visual appeal.
Field identification & locations
Identify by its hardness (scratches glass), waxy luster, and banding (though altered by dye here). Common in rock shops.
