Physical properties
Hardness: 6.5-7 on the Mohs scale, Color: Vivid magenta/pink due to artificial dyeing, Luster: Vitreous to waxy, Crystal Structure: Trigonal (microcrystalline quartz)
Formation & geological history
Formed in cavities of volcanic and metamorphic rocks through the deposition of silica from groundwater solutions over millions of years; later artificially dyed for decorative purposes.
Uses & applications
Used primarily for decorative items, coasters, jewelry, and crystal collections.
Geological facts
Agate is a common variety of chalcedony. The vibrant pink color is not naturally occurring and is achieved by soaking the porous stone in dye.
Field identification & locations
Easily identified by its concentric banding patterns (though sometimes obscured by deep dye) and waxy luster. Common worldwide, especially in Brazil and the USA.
