Seeking information on the COE for Austrian Glass or old Swarovski Ar
Glass, so I can test a sample from the 41 kilo lot of beads from th mid-1980s that I am looking to sell. I'm a stringer, not a lampworker so my knowledge is lacking. Unable to find this info on the Swarovsk or other websites. Thank you! Cl. snipped-for-privacy@canaveralshores.co
