I thought about that, but I'm not sure. Considering how well other beads are copied, these would be a poor match. The beads are a lot smaller, the small rings are only about 6/7 mm. The colours are different, and the wedding beads were not usually made of transparant glass.
Perhaps they are more a copy of Chinese old beads?
And perhaps it is just a one time experimental batch that was spread around the market.....
