Red-orange coral beads (likely dyed or polished coral)

Biogenic calcium carbonate, chiefly aragonite (CaCO₃); coral species cannot be identified from the image

AI-generated identification · may be incorrect

Irregular, polished orange-red beads with occasional pale areas. Coral is typically Mohs 3–4, with a vitreous to waxy luster and a fine-grained, non-cleavable structure; dye or coatings may alter appearance.

Physical properties

Formation & geological history

Coral skeletons form in marine environments as colonies of tiny animals build calcium-carbonate structures. These beads appear worked from coral material; the specimen’s age and natural color cannot be determined visually.

Uses & applications

Used as jewelry beads and collectible ornament; coral is also studied as a record of marine environments. Trade in some coral species is restricted.

Geological facts

Coral is an animal-derived gemstone rather than a mineral crystal. Red and orange coral beads are often dyed or treated, and appearance alone cannot confirm species or authenticity.

Field identification & locations

The irregular bead shapes and color variation are consistent with worked coral, but shell, resin, or other materials can resemble it. Common jewelry sources include Mediterranean and Indo-Pacific coral; seek a gemological test for confirmation.
