Antique Deco .75ctw Diamond 4 Carat Blue Sappphire Platinum Cocktail Ring Circa 1930




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.
