Physical properties
Hardness: 6.5-7.0 (Mohs); Color: Naturally translucent white/grey with artificial bright pink patches; Luster: Waxy to vitreous; Structure: Microcrystalline (Cryptocrystalline) quartz; Cleavage: None.
Formation & geological history
Formed in volcanic rock cavities or sedimentary geodes through silica deposition from groundwater. This specific specimen has been tumbled and chemically dyed after extraction.
Uses & applications
Ornamental use, chakra stones, jewelry, decorative aquarium gravel, and pocket stones for collectors.
Geological facts
The vibrant, saturated 'neon' pink color is not naturally occurring in quartz and is achieved by soaking the porous stone in chemical dyes. Agates are porous because of their micro-structure, which allows them to take on color very well.
Field identification & locations
Identify by looking for concentrations of color in cracks or pits, or colors that seem too 'electrical' to be natural. Natural pink minerals like Rose Quartz or Rhodonite will have a more uniform or earthy hue.
