This piece of jewelry I played with the idea of a ring that can also be worn as a pendant. The secret is in the shank. It has cut outs to except a chain. Besides the functional challenge, the piece needed to have an interesting profile and top view at the same time. A spherical pearl fit the bill. I flush set a couple of diamonds and varied the surface treatment by stone wheeling the top edge.
