This big, bold, and blazingly beautiful Art Deco engagement ring - circa 1920s-30s - features a bright white and sparkling old-mine cushion-cut diamond weighing in at just under 5 carats (4.97 carats to be exact). The gorgeous stone (accompanied by a digital GIA Diamond Grading Report stating: I color - SI1 clarity) beams brilliantly atop a delightful, distinctively designed bow motif mounting, hand fabricated in platinum, aglitter with numerous small round diamonds and accented with calibre sapphires on the shoulders. Decorative hand engraving and millegrain detailing add the finishing flourishes to this breathtaking Jazz Age jewel. Currently ring size 5.

Center Diamond details
Cut/Shape: Old Mine Cut* *Lang determines cut/shape based on visual appearance and knowledge of antique cuts. The GIA laboratory uses mathematical parameters to determine the cut/shape for their reports which can result in differences between Lang and GIA cut/shapes designations.
Carat Weight: 4.97 carat Because mountings prohibit full and accurate observation of gem quality and weight, all data pertaining to mounted gems can be considered as approximate unless accompanied by an independent laboratory certificate (AGL, EGL, GIA). Unless otherwise stated, all colored stones and pearls are assumed to be subject to a relatively stable and possibly undetected color and/or clarity enhancement.
