I've shown this bead before, but it seems to be made and printed by the same method as your bead. And there are large, round beads on the porcelain bead sample card - so I think my bead is from the same workshop.

My bead is 29 mm diameter, and has a large, 8 mm hole. I haven't taken it off the original bail it had when purchased (Lewis Collection 2010) but by peeking inside as much as possible, it doesn't look hollow.

Thanks Floor & Hans for posting the card & bead - I think I have an ID on my bead now!
