Contemporary usage
In the United Kingdom and the United States in past generations, women wore wedding bands much more commonly than men did. Today, both partners often wear wedding rings, but where occupations or professions forbid or discourage the wearing of jewelry (as in the cases of actors, police, military pilots and electrical workers), either marriage partner may not wear a ring. In addition, people often remove wedding rings for comfort or safety. Others may object to the idea of precious metals, or dislike the idea of declaring their legal status through jewelry. Either partner may also wear a wedding ring on a chain around the neck, thus conveying the socially equivalent message to wearing it on a finger.
In England, during the second world war, marriages rose with 300 % and 80 % of the men married in uniform. Because of these circumstances a new type of wedding ring came into fashion: the 'eternity ring', which was a circlet of diamonds, set in platinum and worn like a guard on top of the engagement ring. The eternity ring was bestowed after the marriage by the groom and before he left for active duty in the war. Sometimes a ring with sapphires was also used as an eternity ring, with the color blue as a symbol for 'eternity'.
The double-ring ceremony, or use of wedding rings for both partners, is a relatively recent innovation. The origin of the practice is uncertain, but it was never widespread. The American jewellery industry started a marketing campaign aimed at encouraging this usage in the late 19th century. The practice never became widespread, although it did warrant mention in an etiquette book in 1937. Learning from marketing lessons of the 1920s, changing economic times, and the impact of World War II, led to a more successful marketing campaign, and by the late 1940s, double-ring ceremonies made up for 80% of all weddings, as opposed to 15% before the Great Depression.
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 should be worn alone. Further, modern ring sets in the United States are often marketed as a three-piece set, including the man's wedding band, the woman's engagement ring, and a slender band that is mounted to the engagement ring before the wedding, converting it into a single, permanent wedding ring.
