I think these are actually cloisonné beads.

What has caused you to think otherwise?

I advise you to edit the duplicating posts. You cannot remove them. But you can take out the text entirely, and change the titles to "No Content."

Good luck! Jamey

The Beijing Enamel Factory network produced a type of plique a jour cloisonne starting in the late 1980-90s?

Attached is a picture of a box of these beads. Because the enamel filling is a translucent glass, you can shine a light through them.

I don't know if your beads are Chinese, but that's where I'd start when making a comparison.

Hello Chris,

I have handled some plique beads, so I am familiar with them. Are you certain of the time? I received my first ones in 1991—and they did not seem new.

I was not struck by an idea that the enamel might be unbacked, and I'm inclined to doubt it.

Note the distribution of the cloisons, near the aperturs. Rather odd I'd say.

P.S.—I am now supposing that plique is a possibility. It would have been helpful had the owner mentioned the beads allow light to pass through—making a typical cloisonné manufacture impossible. I still see a difference between these and the beads I've seen from the '90s. In the early 2,000s I was at a show where a seller had a big basket-full of these beads. I was very surprised. And I told the seller he or she (I don't recall which) was offering them at too-low a price. I suppose this might be possible with "newish" beads—though I have seldom seen them offered for sale before or after that.

Plique a jour brooches that the seller says are unsold stock from the late 1980s.
