Vintage Chanel necklace

Vintage Chanel necklace. Don’t know much about it as it was a gift but it’s so beautiful. Can be worn long or chain can be double up. The only flaw is one side where pendant is attached is broken but I didn’t even notice it until I decided to sell it so you can not even tell when wearing it and it does not affect the ability to wear it. I do not know original price but it made me put one.
