Princess cut pink sapphires alongside diamonds give this classic 4-prong eternity ring a look that is sweet and demure. The 4 prong setting is a good option for offering added security to your diamonds and highlighting your choice of precious metals. Each stone in a four prong setting is held into place by four individual bits of metal not shared with another stone. Our diamond eternity rings are offered in 14k and 18k white, yellow, & rose gold or flawless .950 platinum. Select from a wide range of carat weights in stock in most styles, in GH/I1, GH/SI, and FG/VS color and clarity.
