The classic sparkle of round diamonds it at its peak in this platinum u-shaped eternity setting, a style that makes a gorgeous and unconventional wedding band. 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 and 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 eternity bands in exquisite .950 platinum can be set with your choice of gemstones, and we offer a wide range of carat weights in stock for most models, in GH/I1, GH/SI, and FG/VS color/clarity grades.
