Since I made glassbeads myself, at some point, I am at a loss to explain, how this beads has been made. I am not sure many contemporary beadmakers were able to copy this copy in same precision.

I am not even sure, the lines - later to be raked - have been applied with the obligatory "stringers".

The bead is clearly torch-made! No doubt about that. Still - how this industry has been able to execute such a tricky design, with only a limited experience on their belt, is literally above me.
