Art Deco 4.20ct platinum diamond necklace, circa 1920

Staff favorite!   Platinum necklace with 4.20cts in diamonds.  The pendant alone measures 1 5/8" x 3/4".  The chain is 14k white gold and measures 17" long.  All the diamonds are old cuts, very bright and well matched.  Excellent condition, circa 1920.  

I'm gonna miss this when it sells!
