A wedding ring or wedding band is a metal ring indicating the wearer is married. Depending on the local culture, it is on the base of the right or the left ring finger. The custom of wearing such a ring has spread widely beyond its origin in Europe. Originally worn by wives only, wedding rings became customary for both husbands and wives during the 20th century. According to some customs, the wedding ring forms the last in a series of gifts, which also may include the engagement ring, traditionally given as a betrothal present. This tradition was already in use in Ancient Rome and is possibly much older. Historically, the wedding ring connected to the exchange of valuables at the moment of the wedding rather than a symbol of eternal love and devotion. It is from the times when marriage was a contract between families. After marriage, the ring worn on the hand placed on during the ceremony. By wearing rings on the fourth finger, a married couple symbolically declares their eternal love for each other. This has now become a matter of tradition and etiquette. One interpretation states that the woman wears the wedding ring below the engagement ring, thus making it closer to the heart. Another practice holds that the woman should wear the wedding ring above the engagement ring, thus sealing the atmosphere of the engagement into the marriage. Still others prefer that the wedding ring worn alone. Further, modern ring sets in the United States are often as a three-piece set, including the man's wedding band, the woman's engagement ring, and a slender band that mounted to the engagement ring before the wedding, converting it into a single, permanent wedding ring. Some cultures exchange additional rings: In some parts of India, Hindus may use a toe ring worn instead of a ring on a finger, although this is only for women, and increasingly worn along with a finger ring. In Romania, spouses celebrate their silver wedding anniversary by exchanging silver wedding rings, which worn on the fourth finger of the left hand along with the original wedding ring. The wedding ring removed for comfort or safety. It is common for those who have professions that forbid the wearing of jewelry, such as police officers or electrical workers. In some jurisdictions, those in the food service industry may be required to remove all jewelry while handling ready-to-eat food, including wedding rings, unless they are simple, smooth rings. Physicians known to prefer smooth, simple designs, some may even autoclave their rings on a regular basis. Many times these people say they wear a "ring around their heart" not around their finger. Some will wear it on a chain around their neck to compensate for the inability to wear it on a finger.

Rings

A finger ring is a circular band worn as a type of ornamental jewelry around a finger; it is the most common current meaning of the word ring. Other types of metal bands worn as ornaments called rings, such as arm rings and neck rings. Rings worn by both men and women and can be of any quality. Various ring shapes and styles exist. The following are but a few. Flat wedding bands are the simplest form of ring. A flat wedding band consists of a strip of metal bent around into a loop and joined where the ends meet. Half-round rings, also called D-shape rings, are flat wedding bands filed half-round on the outside. Sleeve rings are rings that consist of a thin inner ring or sleeve, with several other rings stacked onto it to form one solid ring. Either the rings soldered onto the sleeve or the ends of the sleeve can be upset to keep them all together. A little of both can also be done. Solitaire rings are rings with a single large stone as a centerpiece, usually a diamond. Eternity rings are rings with stones, usually diamonds, of the same cut and size, set in one row all around the ring. The stones are usually round or square, and the setting is usually either claws or a channel setting. When the stones do not continue around the entire ring, but stop halfway around the finger, it is a half-eternity ring. Trinity rings or Trilogy Rings are three rings worn at one time. Cluster rings are rings with a group of stones in a cluster setting, forming the focal point of the ring. The cluster setting usually consists of one large stone in the center surrounded with several smaller stones. Tension Rings are a type of ring in which a single gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone. In the United States and Canada, ring sizes specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch in diameter, or roughly 1/10 inch in inside circumference. Generally, sizes in quarters and halves will not relate conventionally to anything on any known ruler. On one finger alone, a person may vary more than a whole ring size- depending on time of day, work performed, and other swelling-inducing activities/conditions. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring.
