Round cut pink sapphires and white diamonds practically glow in these stunning u-shaped eternity band settings. U-prong settings developed out of variants on the four prong setting, in answer to the demand for a setting less likely to snag on clothing or other objects & better structured to allow more light to pass through the gem stones. This setting operates by securely holding the gem stones in place slightly above the base of the U. Our eternity bands are available in 14 karat & 18 karat white, yellow, & rose gold or immaculate .950 platinum. Choose from a broad range of total carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color/clarity grades.
