Early sketches of the ring. The idea was a silver-toned ring that cradles the stone like waves crashing on a beach.  

Illustrator mockup of the ring showing more detail. This is what I sent to the jeweler.  

3d rendering of the ring from the jeweler. I made some minor modifications and sent it back for the ring to be cast.
