when do you traditionally buy an eternity ring
Eternity ring An eternity ring, also known as an infinity ring, is a woman's ring, worn on the hand, comprising a band of precious metal (usually gold) set with a continuous line of identically cut gemstones (usually diamonds)[1] to symbolize never-ending love, usually given by a spouse to his or her wife on the occasion of a significant anniversary, typically after 1 or more years of marriage date[citation needed] Because the presence of stones all the way round the eternity ring can make it cumbersome to wear, the alternative is to have the stones across the face of the ring only. This is sometimes referred to as a "half-eternity" ring rather than a "full" eternity ring.
Wedding ring 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.
