Physical properties
Hardness: 6.5-7 (Mohs scale), Color: Hot pink with dark banding, Luster: Vitreous/Waxy, Crystal Structure: Hexagonal (Microcrystalline), Specific Gravity: 2.6
Formation & geological history
Formed in volcanic cavities or sedimentary rocks through silica deposition from groundwater. This specimen has been tumbled and artificially dyed to achieve its neon pink color.
Uses & applications
Used primarily for decorative purposes, jewelry (pendants, beads), and as pocket stones or gifts.
Geological facts
Agate is naturally gray, white, or brown; the bright neon pink seen here is almost always the result of a chemical dyeing process that permeates the porous bands of the chalcedony.
Field identification & locations
Identify by a waxy luster and the presence of parallel banding. If colors look unnaturally bright or concentrated in cracks, it is likely dyed. Common in Brazil and Uruguay.
