A ring is a round band, usually made of metal, worn as ornamental jewelry. The term "ring" by itself denotes jewellery
worn on the finger; when worn as an ornament elsewhere, the body part is specified within the term, e.g., earrings, neck
rings, arm rings, and toe rings. Rings fit snugly around or in the part of the body they ornament, so bands worn
loosely, like a bracelet, are not rings. Rings may be made of almost any hard material: wood, bone, stone, metal, glass,
jade, gemstone or plastic. They may be set with gemstones (diamond, ruby, sapphire or emerald) or with other types of
stone or glass.
