the spacer bar with many parallel holes looks to me like a strip of plastic or rubber such as often seen on the Maasai collars from Kenya, (east african neighbour of Ethiopia) the collars were made with almost rigid wire in a concentric layout with wonderful coloured small beads.
the green moulded beads must be Czech, surely?
the white based red drawn beads appear in your photo not to have the vintage rose-red colour glass made with a gold ingredient, but are rather more orange-red, so surely mid-20th c. as you say. i still have more than a kilo of them that i bought in Venice quite a few years ago.
The tough grass or plant stalk stringing material visible at the knots looks very much like the twisted cords on which beadwork strips also were strung in Kenya for the waist.

Hi Giorgio,
It looks like this is a detail of an Oromo or Arsi necklace and indeed a modern version.
Did you try UV light on the Green mold pressed beads?
If they are fluorescent they are in anyway made in Gablonz.
best wishes Hans

Hi Hans,
indeed the green molded beads glow brightly in UV light. I'm accustomed to machine made Czech molded beads with a seam at the equator, perpendicular to peforation. In these the seam is a line in the sense of the meridian, parallel to the peforation: how are they made?
Giorgio

The mold line surprises me too. It is usually the other way with molded beads.
Could they be wound beads, that are molded with tongs? That way, the seam is in this direction. Perhaps you could look at the holes. Any sign of winding?
However, they are very likely Czech, considering the uranium glass.

About the black and white beads. They have been made in Venice, but also in large quantities in the Czech Republic. And, they have also been produced for quite some time in India now as well.

Hard to see from a picture but is here a possibility the beads are plastic instead of glass? Light in weight, hot needle test?
Plastics can glow with UV light too and also you can find mold lines parallel with the perforation of beads.

Bingo! Hans, your suggestion proved successful, I made the hot needle test and the green beads are definitely plastic. The similarity with glass was such that I didn't even suspect they were plastic. Thank you Hans, and thank you Floor too: now I understand because, notwithstanding yhe presence of small bubbles, they didn't show traces of orientation due to winding or drawing.

A lot of inexpensive beads were made from polystyrene, until acrylic took over as the main plastic material for beads - not sure exactly when. It is hard to find any new polystyrene beads - I've looked! On the other hand, I have a few sample cards from Czech R. with polystyrene beads from the 1960s - sorry none look like yours. Also, all of the "new old stock" plastic beads I picked up in Czech R. earlier this year were polystyrene beads. Polystyrene was a commercial product starting in the early 1930s and it seems a lot of bead and other article production switched over from Celluloid to polystyrene in the 30s and 40s. The injection molding technology is the same for both materials. I saw a display on this in the museum in Neugablonz. Very hard to know for sure whether your beads are pre- or post- WWII. Note: Neugablonz was founded after the war, but the museum has a lot of info about the history and industry of the people who left (well, forced out of) Gablonz to found Neugablonz.

Polystyrene beads used in ethnic compositions are frequently very pitted and scuffed-up since they are not very resistant to wear, as compared to acrylic, which is harder. This gives people the impression that they are "quite old". Or, since the gloss wears off quickly, I've seen people confuse polystyrene beads with old amber since old amber can have a similar non-glossy, pitted surface. Occasionally there are light yellow polystyrene beads being sold as "lemon amber" for example.

hi Giorgio, can you show a picture with an overview of the complete necklace?
Thx

Here is the whole necklace; total length about 60 cm.

Yess, what I thought looking at the first picture. The necklace is made in the style of the Oromo or Arsi people in Ethiopia, best wishes Hans

Dear Georgio,

The short white cylinders that have black trails on each end are Central European, and appear on sample cards. They were not, to my knowledge and memory, made at Venice. In point of fact, these are copies of German (Idar-Oberstein) banded agate beads; that themselves imitate more-ancient beads from Asian find-places. The original beads were probably made in India.

Viewing your necklace, I have to suspect it is more recent than you may be inclined to believe.

Be well. Jamey

This type of beads were wound made in Bohemia and Venice and Prosser type pressed at Briare .
We have in our Museum an undated sample card from the Conterie showing these beads.
There are also on card Fig-157 of the Giorgio Teruzzi new publication that just came out.
Here is a picture from our Museum mixed with eye beads for Thessaloniki and a picture of the ones from Bapterosses in the Briare Museum.
