Yes! i have a short strand of these ancient beads! I bought them in mauritania along with a group of interesting beads from the Islamic era! The face beads that are in the link that you posted sure look FAKE to me but, these beads are indeed authentic and are similar in cost as some of the more common Islamic beads!

They are Islamic period beads, folded glass. Meaning the striped effect is folded glass, the "stripe" pattern goes all the way through, the white is not applied like trail decorated glass (I have a broken one around here that surfaces every now and then)

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 (!)."

Hi luan
i had some also and they were among roman and pre sassanid beads.
here are pics.

Yes, the site I linked to is goofy, I just liked the beads! :^)

I truly appreciate learning the true story about all the beads I love. Some people responded to a post I wrote (on my blog) on some new jewelry pieces I'd made, asking about some galls beads, and I linked to sites that had pictures of various beads I was using, and where the beads could be purchased.

Unfortunately, there was also a lot of misinformation and misleading text connected to the images, so I took the links down when Jamey pointed that out.

My problem is, I personally don't mind copies or "fakes" if I like the bead, nor do I collect valuable beads just because they're valuable. I have to like them first, then be willing to pay the asking price, whether they're real or not, if they're worth it to me. Not very scholarly of me--I admit I can be intellectually lazy when it comes to things I love.

But I also don't want to deliberately participate in deception and chicanery. :^)

At Jamey's suggestion, I went to this guy's site you link to for the first time in awhile.....the 20th c. (and prob. still in production) Czech glass beads for the Muslim market (see below) are declared to be ancient Pyu glass!

( I want some of what he's smokin'....)

Here's a different bead from a similar design series from the Picard site. I noticed an eBay seller recently sell a small strand of these black ones for 41.00, represented as black coral! Mold marks included! #121188248910

I have some of these beads as well, and tried replicating some by lampworking. Wgen looking at them up close, I had noticed that the white lines were always parallel to each other all the way through. Was pretty impossible to recreate by lampworking. Could not understand their procution method.
Them being from mosaic blocks makes me understand the concentric parallel lines. Looking at mine up close, I think some are indeed only cold worked, and some have seen some heat at some time. Some actually have the corners ground off, making them 'cornerless rectangles'.

Mine came from two sources: a mixed strand of mosaic Roman and Islamic period glass beads and fragments bought in Tucson, and some from a mixed strand of all sorts of beads bought in Iran.

The red molded glass beads are indeed still being made in Czech. Was once at a stand of a Dutch dealer where one buyer was also convinced they were ancient. I had a picture of a full Islamic prayer set made form Czech beads with me on my iphone, and that sorted the debate quickly.
