I wonder what is your take on the carved blue and green….are they glass or real stones?
Thank you.
Here it is

 

What did the auction say about materials? From the construction my gut says costume and glass from these few photos but there are others wayyyy more experienced than me here!

 

I'd say glass was well...

 

My thought was glass too because of what appears to be discoloration of the "diamonds." But a very sophisticated design.

yours compared to a Cartier...... notice the differences..

 

I'd say glass; it's extremely rare to find one of these with real metal and real stones. I've only found a few that were even brass instead of pot metal. The stones except the molded glass appear to be glued, and the glue has yellowed. If you're lucky, this is half of a vintage Duette pin, and you run across the rest.

 

I like all of them, but especially the last one with red and ivory colors. It seems more unusual. Maybe it's from the '70s or early '80s as @evelyb30 mentioned. Does that one have a clasp? Or is it very long so it can just go over one's head?

 

There was a lot of jewellery, the house did not give any individual description of items. The paste stones are not diamonds for sure, but the brooch/ clip is 935 silver, probably not made in the UK. Any thoughts, was it made somewhere in Europe?
Thank you.

 

The last one with red and the mother of pearl are a matching necklace and a bracelet, the necklace has a hook type closure. Will try to post some photos of it as well.

If it's red enamel with MoP inlay, it could be French. I've seen that combination before.

 

I would guess glass for the carved parts, but very nicely done.

Seeing the back, it's a very solid looking piece. The fact they used 935 silver, a bit above average for sure.

 

Germany or Austria.
And another vote for glass.

 

Just glass. Swarovski would have the swan mark.

The round turquoise beads are turquoise composite, so turquoise chips in a bonding agent. Pretty necklace.
