Physical properties
Hardness 7 on Mohs scale (for quartz/agate), artificially dyed blue with crackle effect, vitreous luster, microcrystalline or macrocrystalline structure with induced fractures.
Formation & geological history
Formed as natural quartz or agate (often igneous or sedimentary origin), then heavily modified by humans. The stone is heated and quickly cooled to create fractures (crackle effect), then soaked in dye to fill the cracks.
Uses & applications
Used primarily in inexpensive jewelry, craft projects, and decorative items due to its striking, unnatural appearance.
Geological facts
This is a man-made enhancement of a natural stone. True agate or quartz does not naturally exhibit bright neon blue dye settled exclusively in a web of fine cracks.
Field identification & locations
Identified by the intense dye concentration in the fractures. Common in bead shops and craft stores. Not considered a natural specimen by collectors.
