these look like the late '80s/90s rough furnace-wound beads made in India in great quantities, threaded up into a necklace with an old vintage British Empire coin repurposed as a fastening component. they are sometimes used to fasten necklaces including multistrands. threaded in a "traditional" ethnic way-
Ah ok, thanks Stefany. I was fooled by the coin, thinking they might be just a bit older than 80s/90s!
I agree with Stefany.
The Naga rage was over by the early 1990s when most of this material culture was depleted from seller inventories. Glassmakers in India stepped in and began cranking out imitations—most of which were not and are not authentic-looking.
In addition, the line (fibers) used to finish this necklace is very different from the lines typically used on authentic Naga pieces.
