The dramatic statement of rubies is the perfect addition to a sparkling diamond eternity ring in an elegant u-shaped setting. U-shape settings grew from variants on the four prong setting, due to the demand for a setting less likely to snag on clothing or other objects and better engineered to allow more light to pass through the gems. This setting operates by securely holding the gems into place slightly above the base of the U. Our eternity diamond bands are available in 14 kt & 18 karat white, yellow, and rose gold or exquisite .950 platinum. Select from a wide range of carat weights in stock for most styles, in GH/I1, GH/SI, and FG/VS color and clarity grades.
