A reimiro is a crescent-shaped pectoral ornament once worn by the people of Easter Island.
The outer, display side had two small pierced bumps through which a cord was strung for hanging it.
The inner side contained a cavity that was filled with chalk made from powdered seashells.
Although the human faces on the reimiro are unique to Easter Island, the pectoral itself is part of a wider tradition.
In the Solomon Islands, for example, women wear shell pectorals which resemble reimiro.
