This 14-karat white gold ring mounting is semi-mounted with two 3-pt., two 2-pt., and two 1-pt. round accent diamonds along the ring shank and 12 1-pt. round accent diamonds in a halo encircling the center stone mounting (SI1 clarity/G, H color; 24 pts. TW)—all the diamonds are in shared 4-prong mountings. The bezel mounting holds one .40-ct. (4.75mm, approx.) round faceted stone. Bead detailing and ridged patterning on the sides of the halo and shank add interest and texture to the ring. Cut a seat into the top of the mounting to hold the girdle of your stone, then burnish the walls over the stone, securing it in place.
