IMHO, your beads look like typical 18-19th century, drawn, a speo beads, not new copies. I believe they are either Dutch or Venetian.

Perhaps the person who thought they were new copies has confused them with similar lamp beads that were made to imitate the older, 3-layer drawn beads.

These pictures show one of the lamp beads (left) together with two similar drawn beads. My understanding is that the lamp beads of this design are old Venetian beads but likely are newer than the drawn versions.

The beads appear consistent with those I have documented, based on the photo. As always, an in-person examination might change my mind.

However, I am not aware that anyone has made compelling (correct technique) copies of a-speo beads. So this seems unlikely.

These two beads don't look right and may well be fairly recent. For one thing, the middle layer is milky. In the old ones, it is much whiter like the stripes. Also, the hole in the one bead appears to have a rough surface suggesting creation by winding. If the beads were drawn, the surface would be perfectly smooth. Furthermore, the blue glass is too dark. The old beads have much more transparency. The reason for the white layer is so that light passing through the outer layer is reflected off it so the bead looks bright blue. If the glass is too dark, light can't pass through it and the white layer is useless and the glass looks black. If these are wound, they are certainly not Dutch since they just produced drawn beads. Venice might be a source but these are kind of sloppy so I suspect another one... but where?

From a picture you cannot be entirely sure, but they seem to me consistent with the original old ones.
This is an interesting and prolific bead with many variations from the light translucent blue to a black outer layer or(saturated purple), internal color layers, number of stripes and sizes.
What size are they?

Thank you very much for all your opinions.
The sizes of the beads are 14 x 18mm and 15 x 17mm.
I have added 2 images from the same beads, which show the beads under light. One has a translucent blue inner core. The other one, which has also a more new looking shiny surface, does not has this.
I have controlled the inner cores from other blue A Speos of my collection and found both, translucent inner core and a less translucent inner core.
The first i think now, it is old, but the second one i still doubt.

Now the lighter blue is suspect to me. Frankly I cannot tell from the picture.
I have not seen new ones yet to judge or compare.
Could it be an uncirculated bead? this would be unlikely but not impossible.
The other looks fine.

Under intense light, my beads have a slightly translucent cobalt outer layer and an opaque inner layer that looks almost black. On one bead, the outer layer is quite pale compared to the others. But I have only 6 of these in my collection so it's a small sample.

I have seen a lot of variation in the opacity of dark cobalt blue beads of all types. In some cases it is easy to tell that the color is blue and in other cases, it is opaque and looks almost black, unless lit with a really strong light. So my suggestion is that both of your beads are old, just not identical.
