Featured glass bead necklace or ??

this necklace is made of 4 rows of white-metalic beads and 4 rows of pitch black bead

necklace has a two-row gold-tone metal fligree clasp and it is not marked.
beads have different widths and thicknesses.

would like to know what kind of material it may be made of and
from which period it originates.
thanks in advance and greetings

 

Those black chips might be haemetite. How heavy does it feel and how cold? If you've a magnet, it might react.

 

Ty @Ownedbybear. Its not magnetic.and it weighs in total 125gr. How cold... I have very warm hands and after 2 minutes they still feel cold

 

Cut glass tube beads to my

 

Ty @kyratango would these tubes have been cut by hand or by machine? I ask this question because the pieces are different sizes so I thought they might be handmade glass beads or more natural stones.

 

Most likely a trim saw.... https://kingsleynorth.com/lapidary-equipment-supplies/equipment-grinding-polishing/trim-saws.html

 

looks like dangerous machine!

we rebuilt the bathroom last summer and I helped my husband… well. tried to help. I tried to cut a few tiles myself with a saw but everything broke. and those tiles were 1cm thick...

I think it is very clever if the glass tubes are cut with such a saw.

 

Any idea from which period it originates?

 

From the hardware, 1980s or late 70s. It's not ancient. The beads were cut on a bias, but otherwise like any other bugle bead. Those might be Japanese, but the hardware could be from anywhere and the necklace could have been assembled anywhere they made jewelry. The metal looks like Japan or Hong Kong or Germany, but that doens't mean much.

 

Thanks @evelyb30 .
maybe a very stupid question but are you dilating with hardware to the closure or to the beads???

 

Not a stupid question. 'Hardware' refers to the end caps and the clasp.

 

Ditto.
This is the shape the beads were cut in:

 

Thanks @Anyjewelery

 

&Now I want a po-boy sandwich!

I've never seen this cut of glass or stone beads before. Thanks all

 

Hardware = metal bits. I've seen beads like this before, but I'm not sure if I ever saw an entire necklace of them.

 

Thanks @evelyb30 !
refer you to the white metalic glass beads ? Or the end caps and clasp? Im a bit

 

End caps and clasp. The beads all look to be glass. They have silver paint inside to make them pretty.

 

Okay top, thanks @evelyb30
