This 14-karat white gold ring mounting features a 4-prong center mounting that accommodates one .20-ct. (3.7mm, approx.) round faceted stone and is semi-mounted with one accent diamond on each side of the setting (SI clarity/G,H color; 3 pts. TW). A decorative twist-look design gives the ring a dynamic, eye-catching presentation. Cut a seat in the mounting to accommodate your stone, then burnish the prongs over the stone to secure it in place.
