This resplendent Art Deco engagement ring, hand fabricated in platinum - circa 1920s-30s, beams brilliantly with a bright-white and sparkling European-cut diamond weighing 2.25 carats. The scintillating stone (accompanied by a GIA Diamond Grading Report stating: J color - SI1 clarity) is elegantly displayed between glittering diamond-set ribbons (east and west) and pairs of tiny twinklers punctuated by small triangular sapphires (north and south). Diamond-set shoulders, millegrain edging, and hand engraving add the finishing flourishes to this jubilant Jazz Age jewel. Currently ring size 7 1/4 (the shank is white gold).

Center Diamond details
Cut/Shape: Circular Brilliant 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: 2.25 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.
