Physical properties
Hardness: 6.5-7 Mohs; Color: Neon pink (dyed); Luster: Vitreous to waxy; Crystal Structure: Cryptocrystalline; Specific Gravity: 2.58-2.64
Formation & geological history
Formed as a microcrystalline variety of silica, typically in volcanic and metamorphic rocks. The neon pink color is achieved through a chemical dye process after the stone is tumbled.
Uses & applications
Used primarily for decorative purposes, costume jewelry, healing crystals, and as gift shop souvenirs.
Geological facts
Agate is naturally porous, which allows it to absorb chemical dyes deep into the stone, creating vibrant colors not found in nature.
Field identification & locations
Identify by the conchoidal fracture and lack of natural banding gradients. Natural pink agates are usually much paler (rose) rather than this fluorescent hue.
