This is a gorgeous platinum engagement ring from the Edwardian period. The ring is centered by an old European diamond that weighs 1.23 carats and is EGL certified. The color of the diamond is from F-G with SI1 clarity. The ring has impressive open work, milgrain and engraving design. The size of the ring is 5 1/4 but it can be resized. Accordingly, the Universal Gemological Services (UGS)estimated retail replacement values each of the center diamond for $11,042.00 US dollars.
