Diamond Blue Topaz White Gold Wedding Ring Set, Bisnonna - worn by Bisnonna (great-grandmother) Silvia Mascarin to the daughters of Wexford Jewelers. We pulled a mold off it to preserve the lovely design for posterity. Are we a little bit biased because we love to use it often? Maybe, but maybe it's just pretty enough to sway opinion. Mathematically perfect sides form Art Deco petals, holding the central stone in place, as well as being studded with a diamond each. This is the ring set designed to be worn as a bridal set- engagement and wedding. This ring is notched beneath for the band to fit up inside. The wedding band measures appx 2mm wide and has similar creased detailing on the sides of the band. The top round part of the design measures 10mm around, and the bands each begin at 2mm and widen just a bit as they go around the finger. Total band width (both bands together) at the bottom is just under 5mm. London Blue Topaz center, 3mm. Surrounded by six lovely tiny round diamonds 0.015ct each. Total diamond weight appx 0.09ct tdw.
