The Oathing stone is an ancient Celt tradition where the couple place their hands upon a stone while they say their wedding vows. It is believed this is where the phrase 'set in stone' originates from. Modern couples are now rediscovering this ancient way of setting their marriage. Some are also involving their guests by giving all the guests a stone to hold during the ceremony. If the ceremony is near water the stones can be cast into the water following the ceremony or retained as a keepsake. You do what is best for you I will tailor the ceremony to your wishes.
