Beaded gemstone bracelets, likely lavender jade/quartz and blue-gray sodalite or dumortierite

Probable jadeite/nephrite or lavender quartz; blue beads may be sodalite (Na8(Al6Si6O24)Cl2) or dumortierite

AI-generated identification · may be incorrect

Polished, opaque-to-translucent spherical beads with vitreous to waxy luster. Jade hardness is about 6–7 Mohs; quartz is 7; sodalite is 5.5–6. Color and appearance are consistent with dyed or treated beads, so identification requires testing.

Physical properties

Polished, opaque-to-translucent spherical beads with vitreous to waxy luster. Jade hardness is about 6–7 Mohs; quartz is 7; sodalite is 5.5–6. Color and appearance are consistent with dyed or treated beads, so identification requires testing.

Formation & geological history

Jade forms through metamorphism in subduction-related rocks, whereas quartz forms in hydrothermal veins and igneous environments; sodalite forms in alkaline igneous rocks. Geological ages vary widely by deposit.

Uses & applications

Used primarily in jewelry and ornamental objects; value depends on confirmed material, treatment, translucency, color, and craftsmanship.

Geological facts

The image shows finished jewelry rather than a single natural specimen. Lavender “jade” beads are frequently misidentified or dyed quartz, chalcedony, or polymer-treated material.

Field identification & locations

Check density, refractive index, hardness, dye concentration, and microscopic structure; avoid scratching jewelry. Common sources include Myanmar, Guatemala, China, Brazil, and Madagascar, depending on the material.
