Frederick can no doubt speak to whether these court necklace style pieces are authentic or reconstructions. They list the provenance on a couple of them as "Manchukuo." Really? the Japanese World War II puppet state? Property that PuYi sold off to stay afloat? Something hinky? A misunderstanding?
Bead buyers who have shopped for new beads should be able to recognize just how new most of these beads are. And designers in macrame should be able to recognize the newness of the knotting.
The wonderful carved bits can be cheaply copied in China. And I would have to examine them closely to feel certain they are old. Sometimes, I enjoy seeing the carved parts anyway.
