Physical properties

Opaque to slightly translucent, vivid orange-red, with a waxy to vitreous polish; Mohs hardness about 3–4 and no prominent cleavage. The irregular beads are shaped organic skeletal material, not a crystalline mineral specimen.

Formation & geological history

Coral skeletons accumulate in marine environments over time; jewelry coral is commonly harvested from deep-water colonies. The image cannot establish species, source, age, or whether the color was treated.

Uses & applications

Cut and polished for beads, necklaces, and other jewelry; coral is also collected as a decorative material.

Geological facts

Precious coral is made by marine animals, rather than formed as a conventional rock. Natural coral often shows pores or growth structure, while treatments can intensify its color.

Field identification & locations

The saturated orange color and irregular chip-like shapes are consistent with coral beads, but visual identification alone cannot rule out dyed stone or another material. Coral jewelry is sourced from regions including the Mediterranean and parts of the Indo-Pacific; check trade and conservation rules before buying.
