Art Deco platinum sapphire and diamond necklace

Love this!  Converted from a bar pin, it's a platinum necklace with 1ct in diamonds and sapphires.  The diamonds are all old cuts, VS2-SI1 in clarity, G-H in color.  It measures 1/2" x over 3" long.  It's on a nice long platinum chain, the chain measures 20".  Very easy to wear and it looks good with jeans and a t-shirt!  Circa 1920.
