U-shaped settings like these are a great base for eternity rings, particular styles such as this one featuring princess cut diamonds. U shape settings developed out of variants to the four 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 stones. This setting works by securely keeping the gems in place slightly above the base of the U. Our eternity wedding bands are available in 14k and 18kt white, yellow, & rose gold or immaculate .950 platinum. Select from a wide range of carat weights in stock in most styles, in GH/I1, GH/SI, and FG/VS color/clarity grades.
