As a quick answer, they are not always marked in the same place. Especially if it is a bead that has been in production for years, as molds wear out and new ones are made. I have old style fish with ALE in different places -- both versions are authentic. Some beads don't have the ALE marking due to design issues.
Regarding your two beads, can you post pictures so we can look at them?
Hi Izzy's Mom
Thank you for your post - I felt a lot better after reading it. I have tried taking pictures - with not very much success - but will try to attach them to this note.
I have also contacted the seller to ask for her thoughts as to why there are no ALE and 925 marks. To be fair her comments were along the same lines as your own. DH thinks I should just put the bead on the bracelet and forget about it - perhaps he's right?
