A ring is a round band, usually in metal, worn as ornamental jewellery around the finger, or sometimes the toe; it is the most common current meaning of the word "ring". Strictly speaking a normal ring is a finger ring. Rings are traditionally usually in metal but can be of almost any material: metal, plastic, stone, wood, bone, glass, or gemstone to name a few. They may be set with a gem or stone of some sort, which is often a precious or semi-precious gemstone such as diamond, ruby, sapphire or emerald, but can also be of almost any material.
