A wedding ring or wedding band is a finger ring that indicates that its wearer is married. It is usually forged from metal, and traditionally is forged of gold or another precious metal.
The earliest examples of wedding rings are from Ancient Egypt. Western customs for wedding rings can be traced to ancient Rome and Greece, and were transmitted to the present through Christendom in Europe, which adapted the ancient customs.
Depending on culture, a wedding ring is typically worn on the base of the left or right ring finger. Many spouses wear their wedding rings day and night, causing an indentation in the skin that is visible even when the ring is removed. Another indication of their cultural importance is that wedding rings are among the few items that prison inmates and visitors are permitted to wear.
