The mottled green glass beads were also made by Europeans. But is the cabochon clasp on this piece carved (Chinese) or molded (European)?

In blog post from 2013 I described two sets of old cloisonne beads that are clearly mated in necklaces with Chinese glass - one featuring Boshan-style "starburst" beads, the other that mottled green "Peking" glass made to resemble jade.

Interestingly, the Germans and Japanese both expropriated Shandong province and attempted to set up industries there, so there could be two non-Chinese design sources for these glass Deco-era glass beads.
