The holy grail of jewelry design - a new stone! At first glance, this looks like a bright, electrified, yellow stone. However, when you move your hand, you see a vortex of red, blue, green, orange - all the colors of the rainbow. The only change I'd make, and this is true with all of Marianna and Richard's rings are to buff down or round off the edges of the adjustable split at the bottom of the ring. It can sometimes cut into the finger. Other than that, perfection!
