Beaded bracelet with black and white stone beads

The white beads may be howlite (Ca₂B₅SiO₉(OH)₅); the glossy black beads cannot be identified confidently from the image and may be obsidian, onyx, or another material.

AI-generated identification · may be incorrect

Polished spherical and elongated beads; black beads are glossy, while white beads show gray veining. Hardness and crystal structure depend on the actual stones, so visual appearance alone cannot establish them.

Physical properties

Formation & geological history

If natural stone, the beads were cut and polished from mineral or rock material; howlite forms in borate deposits, while obsidian forms from rapidly cooled volcanic lava. The bracelet itself has no geological age.

Uses & applications

Primarily jewelry and personal adornment; value depends on confirmed materials, craftsmanship, and provenance.

Geological facts

White, veined beads resembling howlite are also sometimes dyed or imitated. Glossy black beads are especially difficult to distinguish visually among natural stone and manufactured substitutes.

Field identification & locations

A close inspection, hardness test, or gemological testing would be needed to identify the beads reliably; the photo does not confirm that they are geological material rather than imitations.
