I haven't been on for awhile as I am traveling but love the men in pearls posts. I ran into this young lad from Dublin who was actually my waiter in Paris and consented to a photo and was interested in Pearl Guide once I talked to him. Hope to see him on here.
I would definitely keep the seals and take lots of pictures of them and the pearls together, as that is your only proof of provenance if you have no paperwork. You might want to decide whether you want to spend the money to have them appraised by Mikimoto and also buy a clasp from them. This way...
