A Gorgeous Antique Sapphire Diamond Necklace, Art Deco Period in Platinum, circa 1920s. The center of this wonderful vintage Art Deco Period piece holds a deep rich blue faceted sapphire measuring about 12 x 5mm oval. The sapphire is estimated at approximately 1.25 to 1.50 ct in gem weight (+/-). It is surrounded by twenty two (22) antique cut diamonds, for an estimated .88ctw in diamonds. The setting is solid platinum as tested and dates to circa 1920-30. The bail and chain are white gold and the chain measures about 18 inches long and could be changed out with one of your existing chains easily if so desired. Overall the pendant measures about 1 inch from top to bottom with the bail and about 1/2 inch wide. It is in wonderful vintage condition with some slight wear to the sapphire mentioned for accuracy as I always do. A truly wonderful estate find.
