Very classic, reversible 15 inch necklace with 3 inch extension and earrings !

I believe this beautiful classic piece of jewelry is either a Napier or Anne Klein. It is so useful as one can change it to wear with brown or black! The only flaw I could see was when I was taking pictures. The last picture on the brown side of the necklace shows one.in the middle of one of the squares I had never noticed it before.. a lovely subtle set of jewelry for work or afterwards!
