The Riviera features sleek lines, and an exceptional high polish finish, with 16 small Passion Fire Diamonds totaling .17carats graduated down the shoulders, from the 1 1/3 carat center, pictured. This is designed to hold a center from a light one carat up to a 1 1/2 carat. The top is about 4mm wide and the bottom shank is 3mm. The shank is comfort fit, extremely smooth finish in 14kt white gold alloyed with palladium. Look closely for the subtle details in this new classic reminiscent of the Tiffany Lucida, or the Michael Bondanza Madison. This is made with 950 pure platinum.
