Did you know that the reason why the ring finger is the fourth on the left hand is because people believed that there was a vein that runs directly from the fourth finger to the heart? Based on this, purported experts in the field of matrimony etiquette wrote that it would only be fitting for the wedding ring to be worn on that finger.
In Brazil, the ring is worn on the right hand until the actual wedding day when it is exchanged to the left. Some say that the ring is more noticeable on the right hand due to the shaking of hands during greeting while others advocate for the left hand because it is protects the ring from wear and tear for right handed wearers.
