A glorious and gleaming European-cut diamond, weighing 2.42 carats (accompanied by a GIA Diamond Grading Report stating: K color - VS1 clarity), beams with mega-watt sparkle from this highly distinctive Art Deco engagement ring, die-struck and hand-finished in platinum during the peak of the Art Deco period -- circa 1925. Eight royal blue triangle-cut sapphires (synthetic, but entirely original to the ring and the period) radiate from the diamond, leading to consummate geometric openwork details dotted all around with single-cut diamonds. A superb and stunning Jazz Age jewel. Currently ring size 6.

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: 2.42 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.
