This 14-karat white gold ring mounting features a 4-prong center mounting that accommodates one .15-ct. (3.4mm, approx.) round faceted stone and is semi-mounted with six .4-pt., four .5-pt., four .6-pt, four .8-pt. and two 1-pt. round accent diamonds (SI clarity/G,H color; 12 pts. TW) in prong mountings. A decorative millgrain edge around the accent stones and a slightly tapered shank create an eye-catching look. Cut a seat in the mounting to accommodate your stone, then burnish the prongs over the stone to secure it in place.
