2 tone Cuban stainless steel oval carabiner necklace 18”

Chain: 18”, 2mm cuban/curb stainless steel Carabiner: 2 tone oval 15x20 mm, oxidized silver(?) Jump rings: gold plated stainless steel I purchased the carabiner as “sterling silver” but it doesn’t have a marking. The oxidation is not top notch. I polished it, but have not managed to unify it across. The variation is not obvious. The opening is quite small, but the lock is strong. Overall, still a good-looking piece but I really wanted a round carabiner (I was sent this oval one). Selling it at a loss because I cannot guarantee that the carabiner is 925.
