Is this just no name costume jewelry? No marking but looks so nice.

I bought this at the thrift store. Love it. It is costume and the inserts even the tiny ones are glass. I am guessing it is just cheap costume and there is no way to identify it? It really is nice.

 

Based on the lobster claw clasp it is fairly recent, sorry, that's all I got

 

Same here - made in the 90s or later. I don't recognize the dangle.

 

Agree with fairly modern cheap costume jewelry.

It looks like one of the small bits was used as a dangle.

 

Another vote for fairly recent.
It is unusual to have an even number of 'elements', those oval pieces. It may have had a pendant or a bigger element in the centre.

 

thank you all, as I guessed. So the thing with the element hanging off the back is called a dangle?

 

The thing as a whole is an extension chain, the end piece is a dangle.
