Pink Dyed Agate
Silicon Dioxide (SiO2) with synthetic pigment
Rock Type: mineral

Physical Properties
Hardness: 6.5-7 (Mohs); Color: Hot pink/magenta (artificially dyed); Luster: Vitreous to waxy; Crystal Structure: Hexagonal/Cryptocrystalline; Cleavage: None
Formation & Geological History
Formed as a secondary mineral in volcanic rock cavities (amygdules) or sedimentary veins. The 'pink' color is achieved post-mining through a process of boiling in sugar and chemical dyes to penetrate the porous structure.
Uses & Applications
Used primarily in costume jewelry, decorative 'tumbled' stone collections, metaphysical healing practices, and home decor items like bookends.
Geological Facts
Natural agate is rarely this vibrant. Most brightly colored agates in shops (pink, teal, neon purple) are artificially dyed to enhance their commercial appeal. The process dates back to ancient Romans who used various methods to change stone colors.
Field Identification & Locations
Identify by looking for 'bleeding' of color into microscopic cracks and a saturation level not found in nature. Found globally in Brazil, India, and the USA. Collectors should know that dye significantly lowers geological value compared to natural rarities.
