The former owner of this necklace (which is missing a dangle and needs restringing) says she acquired it in 1969.

The clasp hook says "West Germany."

Seems like a good clue as to what Chinese cloisonne beads were being produced in the 1960s?

Also interesting that they managed to get exported to a West German costume jewelry workshop? The glass beads do seem consistent with that time frame. Neu Gablonz or Czech, do you suppose?
