Art Deco 1.22 Carat Diamond Platinum Ring - GIA K SI1
A beautiful bright and shining European-cut diamond, weighing 1.22 carats, sizzles in the center of a fancy diamond-set halo in this unique and impressive ultra-sparkler hand fabricated in platinum during the first half of the last century. The scintillating stone, accompanied by a GIA Diamond Grading Report stating: K color - SI1 clarity, originates from the 1920s, while the mounting may have been produced a decade or two later. For a finishing touch, pairs of small single-cut diamonds adorn the tops of the currently size 6 3/4 ring shank. 1.64-carat total diamond weight. 9/16 inch diameter.

Center Diamond details
Cut/Shape: European 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: 1.22 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.
