The wedding ring and its symbolism/meaning varies between different cultures but there is no clear evidence when this age old tradition actually started. Some of the oldest recorded exchange of wedding rings comes from ancient Egypt, about 4800 years ago. Reeds and malleable plants and decorative ornaments were twisted and braided into rings for fingers worn by the women in those days.
Eternity or everlasting devotion of love to a partner is the meaning behind the symbol of the circle for many cultures. Romans adopted the use of rings known as "Anulus Pronubus" and were also the first to engrave them. A tradition still used today in many Westearn Cultures. It signifies immortal love and the more expensive the material used to make the ring which was given to the women demonstrated the wealth of the giver. Still today many of us look at the prestige value of rings and often celebrate amongst friends how one was proposed to.
By 860 rings in marriage were used by Christians and accepted by the church for what it represented. Today it has become a billion dollar industry. This accepted tradition of exchanging rings between lovers would have to be considered the ultimate wedding accessory that symbolizes so much more than a piece of jewellery.
