Physical properties
Hardness: 6.5-7 (Mohs scale), Color: artificially bright magenta/pink, Lustre: Vitreous/Waxy, Structure: Cryptocrystalline, Fracture: Conchoidal
Formation & geological history
Formed as secondary deposits of silica in volcanic or metamorphic host rocks. These specific specimens have been tumbled and chemically dyed to achieve an unnaturally vibrant pink color.
Uses & applications
Decorative use, gemstone tumbling, jewelry (beads/cabochons), and metaphysical collections.
Geological facts
While agate is naturally occurring, the neon-pink color seen here does not exist in nature. Agate is porous, allowing it to soak up chemical dyes that settle in the crystal layers.
Field identification & locations
Identify by the extreme saturation of color which often concentrates in cracks or bands. Found globally in volcanic regions like Brazil and Uruguay.
