Of unidentified maker and country of origin, our best guess is that this spectacular piece was made in Europe and probably does date from the first half of the 1900s. Likely of French manufacture as the French used thermoplastics in very novel ways in the production of jewelry especially.
It does not pass the Simichrome test for bakelite so we are not sure what type of plastic it is but for the feel and weight of it in the hand it feels possibly to be bakelite. We think that if it was celluloid, another possibility, it would be lighter in weight.
The chain measures 22" plus 2 1/4" for the top width of the glorious pendant. The pendant measures 4 3/4" (very large) including the bottom bellflower drop. The pendant is in high relief and is 3/4" thick!
The Total weight is 54gm.
The color is in a shade of green that we can best state as shades of light to dark celadon green. That reinforces the notion of it having been done this way to simulate the color and carving of jade stone.
The accompanying beads enhance this piece in a very masterful way. They are exceptionally produced - pierced floral ones and fluted lozenge-shaped ones. All the elements are typical of the Art Nouveau period.
It is in marvelous condition with no problems.
