A diamond ring is diamond jewelry worn on your finger. Diamond is the hardest kind of gem, and the ancient Romans always thought it represented life and eternity. In Europe in the15th century, the diamond ring was recognized as a symbol of constancy in marriage, forming a tradition of taking the diamond ring as a wedding token.
Wearing a ring is the language of love. In foreign countries, rings are usually worn on the left hand (it is inconvenient for the right hand to do things).
