A single prong design with round diamonds, like this eternity band, has a more delicate look than some other settings and makes your diamonds the focus. In a single prong setting, a small tab of the metal used in the ring is shaped to fit over a small area of two or more gem stones, holding them securely into place while covering a minimal number of the gem. This is one of the best setting choices because it allows the greatest quantity of light to shine through your diamonds. Our eternity bands in immaculate .950 platinum can be set with your choice of precious stones, and we offer an extensive range of carat weights in stock for most models, in GH/I1, GH/SI, and FG/VS colour and clarity grades.
