Round diamonds in a sparkle-maximizing u-shaped eternity setting make a gorgeous wedding band for this modern age. U shaped settings grew from variants to the 4 prong setting, thanks to the need for a setting less likely to snag on clothing or other objects & better engineered to enable more light to pass through the gemstones. This setting operates by securely keeping the gemstones in place slightly above the base of the U. Our diamond eternity bands are offered in 14 karat & 18 kt white, yellow, & rose gold or flawless .950 platinum. Select from a broad range of carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color and clarity.
