Would a 3mm hole be a feature of something made to accommodate a Pandora-style bracelet rivet?
The apparent lack of any sort of buffy grit in the holes makes me skeptical about these being old Chinese glass beads.
The only way to remove mandrel release of any sort - soot, clay, whatev - is by drill polishing the hole, yes? Unless, like the Venetians, one uses copper tubing and then dissolves the copper with industrial strength acid?
I might add the seller listed these beads as Peking glass.
These are big beads with large holes. And I have often thought they may be Chinese.
But they are Venetian.
Here are some thoughts from Wayne at Beadweyr:

knew someone at BCN would be able to pull an ID out of the hat if we just applied ourselves.
Venetian makes better sense. Clean holes, plus the overall shape of the oval does not seem at all Chinese.
Thank you! Wayne's beads and those I posted seem to be one and the same.
