Yellow sapphires, a lesser known color for this popular gem, give diamond eternity rings a cheery burst of color. A 4-prong setting is a terrific option for offering extra security to these princess cut gems & highlighting your choice of precious metals. Each jewel in a 4 prong setting is held in place by 4 individual pieces of precious metal not shared with another stone. Our eternity rings are offered in 14k and 18k white, yellow, and rose gold or immaculate .950 platinum. Choose from a vast range of carat weights in stock for most styles, in GH/I1, GH/SI, & FG/VS color and clarity grades.
