Round black and white diamonds offer an elegant contrasting pattern of precious gems, accented by the simplicty of the one-prong setting. In the single-prong jewelry setting, a small tab of the precious metal used to make the ring is shaped to fit over a small area of two or more gems, keeping them securely in place while covering a negligible portion of the precious stone. This is one of the best setting techniques because it permits the greatest amount of light to shine through your jewelry. Our eternity diamond rings are available in 14k and 18kt white, yellow, & rose gold or exquisite .950 platinum. Choose from an extensive range of carat weights in stock in most styles, in GH/I1, GH/SI, & FG/VS color/clarity.
