Long necklace with green beads, need help dating.

Wondered if anyone could fine a comparable piece to this. It might be as new as 1970's, or could be older. Also wondered what kind of beads/stones this had. They are not plastic for sure. Cold to the touch. The center stone has sort of a shimmer when put in direct light, see 4th photo. Last photo shows back of pendant. This just fits over the head, there is no latch. Thanks for taking a look. Hoping to find something comparable, was at a loss for key words to even begin the search. Thanks.

 

The beads look like what we called Peking glass from the 50s -60s. There may be another name for them now.
Not necessarily used only in imported jewelry.

 

That's it! Thank you, Cluttered. Finding similar now. Here is one very similar, not saying that description is fully correct, but a starting point. I'm finding several online, most describe as Czech. Much appreciated!

I vote Czech. I've some lovely necklaces with that glass and stamped metal. I think yours is older, given the length. 1930s.

 

I was starting to think the same looking at several other examples that were dated to the 30's. Thank you for taking a look, Bear.

 

Most welcome - and that length makes it far more saleable. Most of the ones I have are tiny.

 

I'm feeling 1930s Czech also probably early-mid 30s as the fabrics got thinner and waistlines rose more toward normal by the mid-30s. The length complements 1920s/30s low-waisted Flapper-style clothing.
While it's hard to tell without seeing it in person, the round beads look a bit like Chrysoprase, which was sometimes used during that period. The center stone looks like either Larimar or a good quality art glass. Gorgeous!

 

Thank you, Artsfarm That is very helpful information!

 

This style was reproduced somewhat in the 60s-70s, but certainly not with this fine detail so I vote for 30s as well. Gorgeous.
