Hi. Need some help identifying these beads. They were sold as stone & old, although I thought maybe that wasn't the case. Perhaps newly manufactured trade beads, although the small seed bead rings separating them remind me of some extremely old trade bead necklaces I've purchased in the past. The seed bead rings look to be legitimately old to me, so that made me curious. Any thoughts or information on these would be appreciated! Thanks, Lynne
