Sapphires in classic blue are gorgeous alongside princess cut diamonds in the angular, cool-toned style. The shared prong setting is the best-selling diamond setting style for diamond eternity rings and other diamond jewelry. The shared prong setting technique allows the gem stones to be more closely set & shows more of each jewel than a style using more metal and a greater amount of individual prongs. Our diamond eternity rings are offered in 14k and 18k white, yellow, & rose gold or immaculate .950 platinum. Choose from a wide range of total carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color/clarity grades.
