Chloe+Isabel Vintage Bracelet

Selling two and selling separately. The one on the right is missing a stone - not sure if that matters to some. First person to buy will get choice of which one. This one I am confused about. They are nearly identical but the one on the right (missing a stone) has CI markings. The one on the left in perfect condition has no markings. Willing to work with buyer on price for the missing stone, but again first choice goes to first buyer.
