Venetian glass?

ive acquired a bunch of items recently and amongst them was some jewelry. There are some necklaces I'm trying to identify with no luck. Here they are and thank you. Some of the clasps say sterling silver as well

 

It's hard to tell without a close up, but the blue beads may be sodalite.

 

This is a necklace that I have been wondering about and been meaning to post on the forum. It looks very much like yours, I thought maybe ceramic. When I first got it I thought perhaps lapis lazuli but there are no gold flecks.

Green ones are 1920s/30s Czech art glass. Can't decide on the white and spatter ones.

 

The green looks like 1930s Czech.

The white and gold flecks look like older beads that have been restrung with other beads.

 

Not all lapis has them. E.g., these beads:

 

Swiss lapis, aka blue dyed jasper

 

Thanks Kyratango, think you have settled that query for Prerun and me. This is a a bead I hadn’t come across before.

 

Thanks for the thanks
It can be confused with sodalite too...

 

Good point on the restringing. Nice beads, those.
