Tumbled jadeite or nephrite jade bead bracelet

Jade: jadeite (NaAlSi₂O₆) or nephrite, a tremolite–actinolite amphibole aggregate

AI-generated identification · may be incorrect

Pale gray-green, translucent-to-opaque, smooth rounded beads with a waxy/glassy luster; hardness about 6–7 Mohs, tough interlocking structure, and no obvious cleavage. The image cannot reliably distinguish jadeite from nephrite; the gold-colored centerpiece and green accents may be metal or decorative material.

Physical properties

Formation & geological history

Jadeite forms mainly in high-pressure subduction-zone metamorphic rocks, while nephrite forms through metamorphism and metasomatism; both are geologically ancient and occur in altered ultramafic or metamorphic terrains. Common sources include Myanmar, Guatemala, China, Russia, Canada, and New Zealand.

Uses & applications

Used for beads, carvings, ornaments, and jewelry because of exceptional toughness and attractive color. Pale low-grade material is generally decorative rather than high-value gem jade.

Geological facts

Jade is defined by mineral identity and toughness, not simply green color; many commercial “jade” bracelets are actually serpentine, quartz, or treated material. Specific gravity and laboratory testing are needed for confident identification.

Field identification & locations

Field clues include very high toughness, waxy luster, dense feel, and fibrous or granular texture under magnification; avoid scratching finished beads. Estimated value: about $10–$80 for common commercial bracelets, $100–$500+ if confirmed natural fine jade; centerpiece materials can substantially alter pricing.
