This is an ORIGINAL ANTIQUE COCKTAIL RING that was made in the ART DECO STYLE during the 1930s. It is handmade from PLATINUM (top) and 18K GOLD (back & shank). The ring is centrally bezel-set with 1 SYNTHETIC BLUE SAPPHIRE that weighs approx. 4.15 ct. This sapphire is an ANTIQUE RECTANGULAR CUT of fine color & quality that measures approx. 10.5 x 8.75 x 5.06 mm. Large synthetic colored stones were typically used during this period for the cocktail rings like this and I have several other shapes and sizes available.
The sapphire is framed with a mix of 20 ROSE CUT DIAMONDS of J color, SI to I clarity that weigh approx. .22 ctw. and they each have a .02 – .03 ct spread. There are an additional 6 OLD MINE CUT DIAMONDS (north & south tips) of H to K color, SI to I clarity that weigh approx. .53 ctw. The largest diamond is approx. .12 ct. and the total diamond weight is approx. .75 ctw. One of the diamonds has a very small chip/nick at at the bezel, but you need magnification to see it. The ring measures just over 1” long on the finger by 1/2” at the widest point.
