Princess cut gems look stunning in eternity bands, and these diamonds and bright yellow sapphires are no exception. The shared prong setting is the best-selling gemstone setting style for eternity rings & other precious stone jewelry. The shared prong setting technique allows the gems to be more close-set & reveals more of each jewel than a design using more metal & an increased quantity of individual prongs. Our diamond eternity rings are available in 14kt & 18 kt white, yellow, & rose gold or exquisite .950 platinum. Select from a diverse range of carat weights in stock for most styles, in GH/I1, GH/SI, and FG/VS color and clarity grades.
