Simon G. 18K Tri-Color Gold Diamond Fashion "Wave" RingThis Simon G. diamond fashion wave ring, featuring 0. 49 Carats Round Cut Prong Set Diamonds, creates a layered look that mimics the fluid motion of water across your hand. The clever criss cross design features multiple bands of 18K gold that weave together, giving you a bold look without feeling heavy or bulky. What we love about the MR1854 is that it is the kind of piece that people notice from across the room because it plays with light and shadow
