This is a pair of rings for a gentleman who wanted one wedding band and a silver ring with with obsidian inlay. The pure wedding band was cut with diamond tools from a big piece of obsidian. It was not an easy task. The rock was huge and needed to be cut into manageable pieces. Most jewelers don’t have tools large enough to work with baseball-size rocks. It was done slowly with hand tools. The second ring was made out of silver then a piece of obsidian was carefully inlaid.
