Formation & geological history

Made from the calcareous skeletons of marine corals, formed in ocean habitats over time; the bracelet is cut and polished coral chips. Geological age depends on the source coral.

Uses & applications

Used in jewelry and ornamental carving; natural red coral is also collected as a gem material.

Geological facts

Coral is an animal-derived biomineral, and harvesting some precious coral species is regulated to protect reefs and populations.

Field identification & locations

The irregular chips and saturated red-orange color are consistent with coral, though dyed shell or other imitations can look similar. Common sources include Mediterranean and Indo-Pacific waters; a jeweler or gem lab can confirm identity and treatment.
