In America, an engagement ring is typically worn on the ring finger of the left hand. It is socially acceptable, however, to wear the ring on either hand. The ring is worn with or without a wedding band after the wedding.
The ring finger is the finger located between the pinky and the middle finger. In the past, superstitious couples placed a ring on this finger to ensure a happy, successful marriage; they believed it was the only finger with a vein leading directly to the heart. Many engagement rings are adorned with diamonds or other gemstones. The average buyer spends approximately $6,000 on a ring.
