The ancient Celts lived in close harmony with the land and the many standing stones and stone circles scattered throughout Celtic Europe is testament to that. In some places you may find a large stone with a hole carved through. These are marraige stones. Our ancestors gathered in these places to celebrate hand fastings and engagements. The newly weds would clasp hands through the stone and say their vows,  setting their love in stone so to speak. Bridging the gap and making the connection between themselves, their traditions, and their land. 
This Celtic promise Stone was hand carved in wax then cast with 5g of solid Sterling silver. It was tumbled with ceramic madium to give a rough stone like surface then finished by hand. I gently sanded the edges to emulate the wearing of the stone over time, replicating corners softened by years wind and rain, and by the reverent hands of our ancestors.
