Stan,
after looking at that first pic from above, the larger original bead seems to be off center too..smaller gap at the bottom to the rib than at the top, but that could be camera angle & height of the bigger bead.The little one ain't perfect, but hard to tell where the rib ends in the shadow
tut,
..I guess ,when in doubt, send it back is the wise move.
It would be great to know why its there ,all the same....be a bummer if it was minor
Did either bead look off center when in hands on n up close?
cheers
