Received this as a gift (purchased on Poshmark), but it’s too big for me. I wore it a few times hoping I’d get used to it. Excellent used condition. I believe it’s the 5mm in large. I have another DY bracelet that is a medium and this one is larger and sits much lower on my wrist, which is why I’m guessing it’s a large. Small nick in the pearl — tried to highlight it, but not noticeable if not looking for it (took me a minute to find it). Not sure if I did that or if it came that way and I never noticed. Comes with box, pouch, and (new) cleaning cloth. Beautiful timeless piece!
