Historically, across cultures, engagement rings have been worn on every finger, even the thumb. Here in Australia, and in many Western countries, engagement rings are typically worn on the fourth finger of the left hand. This tradition dates back to the Ancient Romans, who believed that this finger had a vein that ran directly to the heart.Once married, many wearers choose to stack their wedding bands and engagement rings, with the wedding bands typically worn closest to the heart, and thus below the engagement ring. However, some prefer to wear their wedding ring on their left hand, engagement ring on the right. Really, the choice is yours.
