An oath to an eternal union. The round shape of the ring symbolises perfection and eternity. The ring conceals protective powers, as the ring enclosing a finger creates a magical power that dispels evil spirits. Wedding and engagement rings are usually worn on the left hand ring finger, because this finger is believed to have a direct link to the heart. This ring is based on the model of a golden ring, found in the Vaasa region on the west coast of Finland, dating back to the Roman Iron Age, the first centuries AD.
