Tiffany 4.36 Carat Marquise Cut Diamond Engagement Ring - GIA E VVS2
In this absolutely stunning ring, a magnificently cut, supremely scintillating and blazing white 4.36 carat marquise diamond displays its radiant splendor, embraced on each side by a sparkling white pear-shaped diamond. Together, the three stones create a captivating and fabulous flash of light and sparks of prismatic color. Breathtaking! The marquise diamond is accompanied by a GIA Grading Report stating: E color - VVS2 clarity. The diamonds are set in platinum atop a gleaming 18K gold shank. We acquired the ring along with a Tiffany & Co. appraisal from 1979 describing the ring as platinum. We assume that the 18K gold shank, signed 'Tiffany', along with larger side stones, was a later replacement. N.B. - Tiffany appraised the ring in 1979 for $90K which, according to an inflation calculator, is the equivalent of $316,930 today; and 1979 was just before diamond prices went through the roof! Currently size 6.

Center Diamond details
Cut/Shape: Marquise 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: 4.36 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.
