Chanel Vintage Long 70" Necklace with CZs 18 carat gold color Belt / necklace

This was my mother's, vintage (I think 50's) guaranteed authentic Chanel very long 70 inch necklace (also could be a chain belt). One photo shows a chanel glass magnifier she wore it with - that is NOT included, listed separately. It is missing some cz stones that I assume could be replaced. It is 18 karat gold color but is costume jewelry. Condition is consistent with its age and is accurately represented in the photos. I am not willing to sell for less than the listed price so counter offers and things will be ignored. Thank you but I have listed it as low as I am willing to sell it for.
