A ring is any band of metal or other durable material worn around the finger as an ornament, particularly one set with gems. Historically, such rings were used as a sign of betrothal or marriage and also as a symbol of chastity. Increasingly, these rings are used to show an affiliation with a particular organization or cause. They are also frequently given as tokens of friendship or loyalty, such as a corporate membership ring or a military service ring. They are sometimes also used as a token of love, such as a engagement or wedding ring. Rings can also be worn on other parts of the body, such as the toe or in a piercing. The term ring can also refer to the shape of such a ring.
A bangle, for example, is a ring that is circular in cross-section. It is commonly made of a metal such as gold or silver, although it can be made of almost any material, including plastic or wood. The bangle is typically worn wrapped around the hand, but it can be slipped onto other fingers as well. It is often worn with other jewelry, such as earrings or necklaces, in a fashion that is reminiscent of Indian jewellery.
In mathematics, a ring is a set that is closed under addition and multiplication and in which the additive inverse of every element is unique. A ring is also an associative semigroup with respect to addition and has a distributive law for its elements. The ring of integers modulo n is the prototypical ring; its axioms are a generalization of the familiar properties of addition and multiplication. The concept has been extended to more abstract structures, such as cyclic groups and polynomial rings. It has also been generalized to monoids internal to abelian groups and, more generally, to stable homotopy rings.
There are many types of rings available in the market, and it is important for anyone interested in purchasing a ring to know their ring size before doing so. A common way to measure a ring size is by wrapping a piece of string around the finger on which the ring is to be worn, taking note of where the ends meet, and then measuring this against a ruler in millimeters. Ring size charts can be found on the websites of jewelry retailers such as Mejuri.
