Take all the stones out and reuse the white gold to make a white gold band as wide as the metal allows at size 8.75, and resize size rose gold ring up to size 8.75 and add tighter hammered texture to the two tone ring, comfort fit. Bezel set for oval ruby cabochon and slanted off centered set. Five diamonds will be randomly bezel-set (flush set if band allows) in the band and on the edge, diamond setting to be determined. We estimate the cost is approximately $1500-$1800 depending if we can find a calibrated bezel (less labor) or make a new bezel for the oval ruby cab, also if we need to flush set or bezel set diamonds.
