The circle shape of wedding rings represented eternity for the Egyptian. Wearing a wedding ring symbolize the marriage agreement. They placed the wedding ring on the fourth finger of the left hand believing the left hand was directly connected to the heart. The Greeks also believed in this wedding ring tradition thus perpetuating the practice.
However, Elizabethans wore wedding rings on their thumbs. During the Eighteenth century Roman Catholics wore wedding rings on their right hands. Many European women still follow the Roman Catholic wedding ring tradition. The circle shape of the wedding ring represents eternity whether it is worn on the right or left hand.
