I think it's size 13. Please understand that this is a used item, stored at home. I'm hesitant to sell it, so I'm not considering lowering the price. This is the box I received when I bought it from a select shop, but the ring doesn't fit properly, so it might have been mistaken for a necklace box. I will include the box, but the ring won't fit properly. Silver ring Silver 925 Indian jewelry Butterfly Journal Standard BEAMS BEAMS BOY BEAUTY&YOUTH
