Sterling Silver and Copper Ring
The copper bit is from the Lisbon mine in southeast Utah. The process used at this mine produces 99.99 % pure copper. The band and riser are sterling silver. If one were to stand this ring up on a tabletop, it would measure about 40mm/1.5 inches tall. Ring is size between 8-1/4 and 8-1/2. This piece is one-of-a-kind.
