Have a 2.63 round brilliant cut ring mounted on an 18k white gold ring set with 122 round diamonds. These diamonds have a avg clarity grade of VS-2. avg color grade G-H. The 2.63 ct clarity grade is SI-2. color grade H, Triple X. EGL certified with certificate. Mounting was done through Stuller, who I believe they used St. Louis Fabricators as the ones to do it.
