Art Deco 1.30 Carat Diamond Engagement Ring
This original, highly-distinctive Art Deco dazzler hand-fabricated in platinum, circa 1920s-30s, shines front and center with a bright white and sparkling European-cut diamond, weighing 1.30 carats. The elaborately designed, multidimensional mounting frames the stone on all sides with small glittering round diamonds accented at the corners with dark blue diamond-shaped calibre sapphires for a stunning and sophisticated effect. The currently size 6 3/4 ring shank is hand- engraved on three sides, as is the ring's supportive under gallery. Singular and sensational! The top measures 5/8 inch diagonal. Accompanied by a GIA Diamond Grading Report stating: J color - SI2 clarity

Center Diamond details
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: 1.30 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.
Measurements: 7.19 x 7.47 x 3.92 mm
