Princess cut yellow sapphires and white diamonds in a u-shaped setting are a bright and colorful variation on the classic diamond eternity ring. U-prong settings grew from variants to the 4 prong setting, thanks to the demand for a setting less likely to snag on clothing or other objects and better designed 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 wedding rings are offered in 14 kt and 18 kt white, yellow, & rose gold or immaculate .950 platinum. Select from a vast range of carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color/clarity.
