Art Deco Oval Sapphire and Diamond Cocktail Ring

This is a very smart easy to wear quality ring, nice and flat so will not catch on anything. The oval sapphire is approximately 2.90 carats surrounded by 12 diamonds approximately 0.10 carats each = 1.20 carats total plus calibre set sapphires to finish the cluster. All set in platinum with 18 carat white gold back and band. The back of the ring is as fine as the front which is typical of the period. French. Weight 4.63 grams. These were always used to contrast the diamonds and the extra sapphires. The oval setting measures 23.45mm x 18.70 mm across. The ring size is M 1/2 but we have a superb jeweller who can resize without a trace.
