Two shimmery rows meet at the center stone where you can mount a 6.5 mm round diamond or gemstone. 40 side round brilliant cut diamonds are bright set and weigh 0.08 carats total. Made from 18 kt white gold, the four prong crown has a slight split shank at the shoulders. Size 6
This ring is considered a semi-mount, where everything is included but the center has a cubic zirconia as a place holder for visualization purposes, or nothing at all. It is presumed you will be replacing it with a diamond or gemstone.
