Physical properties
Hardness 6.5-7 on Mohs scale; vitreous to waxy luster; trigonal/microcrystalline structure; smooth, polished surface with bright magenta/purple color dye concentrated in micro-fractures.
Formation & geological history
Formed as a natural chalcedony/quartz gemstone via secondary silica precipitation in volcanic rock cavities, then mechanically tumbled and artificially dyed to enhance color.
Uses & applications
Used primarily for decorative purposes, jewelry making, craft projects, pocket stones, and entry-level mineral collections.
Geological facts
Agate and quartz are naturally porous, making them ideal candidates for artificial dye treatment, which allows producers to create vivid, non-natural colors like hot pink and bright purple.
Field identification & locations
Look for unnaturally vivid magenta or purple coloration with dark color concentration along cracks and grain boundaries to identify dyed specimens. Tumbled specimens are widely available globally.
