This 18 kt white gold setting is traditional until you can't take your eyes off of the center two bar setting. It also sits atop a donut to provide security for the round diamond or gemstone that measures 6.5 mm. 20 bright set round brilliant cut diamonds flank the center and weigh 0.10 total carats. 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.
