3 necklaces that I need help with, if you would be so kind

The first one I think is made of Venetian/Sommerso beads. Would that be correct? How old is it? It is 16" with a barrel clasp.

The second one is made of faceted pink glass beads strung together with metal loops. It is 59" long and has no clasp. Any ideas on how old or where from?



And finally the third has me really baffled. It is very heavy at 4.7 oz (133 grams), clinks like glass. The blue beads are very close in size but not uniform. The white ones are flat on one side and many have a dimple on the flat side. It has a toggle clasp that is marked .925 China. Could it really be glass or is it possible it is some sort of natural stone? Am I correct in thinking it is not too old? Maybe from the 70's or 80's?






I have more pictures if needed. I appreciate any opinions or advice. Thank so much for looking.

 

First aren't what I'd call sommerso, they're aventurine with swirled colour. Sixties ish. Second probably Czech, 20s/30s, flapper length.

Last one, fairly recent, might be pearls. And some kind of jadeite.

 

Thank you Ownedbybear. Always appreciate your knowledge.

 

I’ve got some blue beads like the third necklace. I’ll dig them out to see how similar they are but I thought mine were dyed quartz.

 

Thanks for taking the time KSW

 

I'd be thinking amazonite or dyed to look like same on the third one. The second one could be Japanese too; the colors aren't talking to me with any particular accent.

 

Actually, I forgot I have a presidium (duh) and tested the blue stones on the third necklace and they test strongly (as in the needle stays steady) as Jadeite. I don't use the tester much as I am not confident with it.

 

Thanks evelyb30. So I guess the jury is still out on the 2nd.

So is the first one from Japan?

 

Italy, more like. The beads speak Italian and the stringing looks Italian too.

 

Thanks again evelyb30. I thought perhaps they were Italian. When I was researching I saw several very similar and some almost exact pieces that were identified as Venetian and Murano but I still wasn't sure. I still won't call them Murano but Italian works.

 

Yup, I should have said I thought the first is Italian.
