In this u-setting eternity ring, sapphires and diamonds seem to float above the surface of the band, catching light from many angles. U-shape settings originated with variations to the 4 prong setting, in answer to the demand for a setting less likely to snag on clothing or other objects and better designed to enable more light to pass through the gems. This setting works by securely keeping the gem stones in place slightly above the base of the U. Our eternity bands are available in 14k and 18 karat white, yellow, & rose gold or immaculate .950 platinum. Choose from a wide range of carat weights in stock for most styles, in GH/I1, GH/SI, and FG/VS color and clarity.
