for correction and clarification!

"Unfortunately, this is very garbled. These are not (in ant way) "folded" beads. They are mosaic-glass beads made from stratified preformed blocks, that are stretched and divided. In this style, usually cold-divided and lapidary-treated.

These typically derived from Hellenistic and Roman times. I could not say none were made in the Islamic Period. This is possible, of course. But it is unlikely. There might, however, be modern copies of these ancient beads (!)."
