Physical properties
Hardness: 6.5-7.0 (Mohs scale), Color: Yellow-orange (Carnelian/agate), Black (Onyx/agate), White (Etched designs); Luster: Vitreous to waxy; Structure: Microcrystalline
Formation & geological history
Formed through the deposition of silica from groundwater in volcanic rock cavities. Modern Dzi beads are created by etching patterns into natural agate using alkali salts and heat-treatment.
Uses & applications
Used primarily in jewelry, prayer beads (Mala), and as spiritual talismans or amulets in Asian cultures, particularly Tibet.
Geological facts
Ancient 'True' Dzi beads are considered priceless treasures in Tibet and are thousands of years old. This specimen is a modern interpretation, commonly used for aesthetic and symbolic protective purposes.
Field identification & locations
Identify by the distinctive 'eye' patterns and circular bands. Agate beads are cold to the touch and cannot be scratched by a steel knife. Common in markets across Central and East Asia.
