Vintage 1.28 Carat Diamond Platinum Engagement Ring - GIA J SI1 By Granat Brothers
A gorgeous, glistening European-cut diamond, weighing 1.28 carats, performs its magic in the center of this impressive late Art Deco ultra-sparkler hand-fabricated in platinum - circa 1930s-40s, evocative of Golden Age Hollywood jewels. The scintillating stone, accompanied by a GIA Diamond Grading Report stating: J color - SI1 clarity, is embellished on each side with fans of baguette diamonds, and above and below with sparkling round brilliant-cut diamonds for a dazzling dynamic effect. For a finishing touch, the shoulders are adorned with trios of single-cut diamonds leading to a sleek knife-edge ring shank. 2.01 carats total diamond weight. Currently ring size 6 1/2.

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: 1.28 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.
