Ruby and diamond eternity rings are the ideal gift for many occasions; they make wonderful wedding bands, anniversary rings, birthstone rings, and Valentine's Day gifts. The four-prong setting is a very good option for supplying added security to your jewels & highlighting your choice of precious metals. Each gem in a four prong setting is held in place by four individual bits of precious metal not shared with another stone. Our eternity rings are available in 14k and 18k white, yellow, & rose gold or exquisite .950 platinum. Choose from an extensive range of total carat weights in stock in most styles, in GH/I1, GH/SI, & FG/VS color and clarity.
