Physical properties

Hardness: 6.5-7 Mohs; Color: Multicolored (vibrant pinks, blues, greens); Luster: Waxy to vitreous; Structure: Cryptocrystalline; Features: Unique spider-web or crackled patterns.

Formation & geological history

Natural agate that has undergone thermal shock (heated and then rapidly cooled) to create fractures, into which colored dyes are infused. Natural agate forms in cavities of volcanic rock or ancient lavas.

Uses & applications

Primarily used for beads, jewelry (bracelets, necklaces), decorative art, and holistic stone collections.

Geological facts

The 'Dragon Vein' appearance is a human-enhanced effect. The base material is real chalcedony quartz, but the vivid colors and extreme contrast in the 'veins' are the result of artificial treatment.

Field identification & locations

Identify by looking for consistent crackle patterns that hold dye more intensely than the surrounding stone. Commonly found in bead shops and artisanal jewelry markets. To verify, look for the presence of natural agate banding alongside the crackle.
