Czech Antique Necklace Art Nouveau Deco Green Flower Filigree Motif
Gorgeous art nouveau necklace dating to the early 1920s, right between nouveau and deco periods. The slight Asian feel of the stone center is a Victorian revival note, while the delicate floral surround is very art nouveau. The surround looks to be Czech as do the small stones further up from the main pendant.
Stunning piece, I've never seen one quite like it. I have come across many with a large center stone.
