^^ I have noticed that sometimes the stamping on Pandora charms looks a little off. I have had beads that say "AL" yet I am 100% sure they are authentic since I bought them from an authorized resaler. Also, I have had the "925" look like numbers other than that. When checking authenticity, the stamp isn't always the tell-tale sign. Check the details of the beads. Also, it's important to note that several beads have several different designs depending on when they were made. The penguin is a good example of this, as is the perfume bottle.
Thank you Miss Kris. I feel pretty sure mine is authentic and the bead looks exactly like it does on the official Pandora website.
