Last year we had an extended thread about Boshan beads in jewelry.

Recently I acquired what is likely a 1930s necklace with a clasp identical (insofar as hand-constructed clasps can be identical) to the one on the old necklace with what appear to be Boshan beads (the 2023 thread starts with the observation that there are at least two of these Boshan bead necklaces). The obvious conclusion is that these three necklaces came from the same workshop ... but whose? and where?

Anyone have any thoughts about this little mystery?
