Ray ban rb4246 990 - Gem。Absolutely love these glasses! A small piece of the plastic frame broke off, so the one side of the lenses does come apart. I have super glued and have had no issues for quite some time with them staying. Doesn’t impede on the usability at all. Lenses are polarized, and do show some slight scratches due to regular wear. There are a few small marks on the gold rim surrounding the bottom part of the lenses. Purely cosmetic and not noticeable when wearing. They are authentic and were originally purchased from Sunglasses Hut. Any questions, please ask!
