Elegant simplicity well describes this sparkling original vintage diamond engagement ring from the height of the Art Deco period - circa 1925. The central bright white European-cut diamond weighs 1.31 carats and is accompanied by a GIA certificate stating H color - SI2 clarity (however, this is one of the best SI2's you could ask for - 90 plus percent of the diamond is as clean as a whistle and it most definitely appears clean to the naked eye). The delightful setting, die-struck and hand finished in platinum, features a tapered stripe of deep blue French-cut sapphires (*synthetic) down each shoulder, light and lovely open scroll work, and decorative hand engraving. A beauty! *Back in the day, circa 1920s-30s, due to their color consistency and flawless clarity, synthetic sapphires were considered a modern improvement over their natural counterparts; besides the fact that the subtle differences are only detectable with a microscope.

Cut/Shape: Round 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: 1.31 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.
