It is a relic of the days when marriage was a freelance between families, not individual lovers. Both families were then desperate to ensure the financial safety of the young couple. Sometimes it went so far as being a conditional trade as this old (and today old) German formula shows: ‘I come up with this ring as a sign of the wedding which has been promised among us, provided your father gives with you a marriage element of 1000 Reichsthalers’.

By dressed in rings on their fourth hands, married spouses symbolically claim their life-long love for and fidelity to each other. This symbol has public utility, and is almost immediately anticipated as a matter of custom and etiquette, loads in order that its absence is usually interpreted as that means that the person is single. Many spouses wear their wedding rings day and night. When needed because of hygiene or to avoid damage, they commonly wear their rings on a necklace. Some cultures exchange extra rings: In some parts of India, Hindu women may wear a toe ring or “bichiya” instead of a finger ring, but the bichiya is more and more worn in addition to a finger ring. It was a band of sterling silver inscribed with a poem or “poesy”. Other stylesDifferent cultures used many other historical kinds of wedding ring. For instance, see the image below of the Byzantine ring depicting Christ uniting bride and groom. Also, in the Middle East the puzzle ring was a old custom: this ring consisted of a number of pieces that joined in combination into a cohesive band when worn correctly. The object of this variety of ring was to render it very difficult to put on the finger properly such that, if the wife removed it, her husband would know. The fede ring, being a band along with two hands clasped in betrothal, is another historical custom of Europe that ostensibly dates from antiquity.
