This 14-karat white gold engagement ring mounting features a 4-prong center mounting that holds one 7 x 5mm oval faceted stone. A dual split shank creates a dynamic overlapping top view and a decorative side view with accent diamonds and an angular structure that helps support the mounting. The shank and halo are semi-mounted with 82 .35-pt. diamonds (SI1 clarity/G, H color; 28.7 pts. TW) in shared 4-prong mountings. Cut a seat in the prongs to accommodate your stone, then burnish the prongs over the stone to secure it in place.
