Princess cut gems are a wonderful choice for the close-set design of eternity bands like this one featuring black and white diamonds. The shared-prong setting is the most common diamond setting style for eternity bands & other diamond jewelry. The shared-prong setting method allows the gemstones to be more close-set and displays more of each jewel than a design using more metal & a greater quantity of separate prongs. Our eternity diamond rings are available in 14 karat and 18 kt white, yellow, and rose gold or exquisite .950 platinum. Select from a wide range of carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color and clarity grades.
