VINTAGE Guess Los Angeles Chain Bracelet

Stylish Guess Los Angeles chain bracelet with a metallic finish. I've owned this since the 80's and have no idea what it's worth but, I don't see any 925 stamps and, nothing is on the Internet that's similar! ALSO, NOTE THE PICTURES FOR FAULTS such as the chain link closure. It opens and closes fine the way it is but, something is missing I think. The last pictures show other Vintage Guess Braclets for sale. THIS IS VERY RETRO OOL! THE RINESTONES LOOK LIKE REAL DIAMONDS!!
