This is a very fine antique Art Deco platinum, diamond and synthetic blue sapphire ring. All of the stones are original to the ring. The diamonds are extremely fine old European and Mine cut. There are a total of 18 diamonds with a total weight of .80 - 1 carat. I have had the synthetic sapphire professionally polished as it had scratches due to age. It is bezel set and measures approximately 5.5x4.8 mm. The face of the ring is 21x17 mm and it weights 6.11 grams. It is currently a size 5.5. The last three pics are of the sapphire after being polished.
