The bright, cheerful color of yellow sapphires next to classic white diamonds is a beautiful combination perfect for our 4-prong eternity rings. The 4-prong setting is an outstanding option for delivering extra security to your diamond jewelry and highlighting your choice of precious metals. Each diamond in a 4-prong setting is held in place by 4 individual bits of precious metal not shared with another stone. Our diamond eternity bands are offered in 14 kt and 18kt white, yellow, and rose gold or exquisite .950 platinum. Choose from an extensive range of carat weights in stock for most styles, in GH/I1, GH/SI, and FG/VS color/clarity grades.
