A finger ring is a circular band worn as a type of ornamental jewellery around the finger; it is the most common current meaning of the word ring. Other types of metal rings worn as ornaments are also called rings, such as earrings, arm rings, toe rings and neck rings.

Rings can be of almost any material: metal, plastic, wood, bone, glass, gemstone to name a few. They may be set with a 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.

The custom of giving and receiving finger rings dates back over approximately 6,000 years. Tracing exact history is difficult.

The Hittite civilization produced rings including signet rings, only a few of which have been discovered.Old Kingdom Egypt had a variety of finger rings, and a few basic examples have been found, including the famous scarab design. Egyptian rings became more common during the middle kingdom, with increasingly complex designs. The various Egyptian styles were replaced by Greek and Roman fashions during the Ptolemaic dynasty.
