Large Gold Tone Pink Glass and Stone Necklace ID

Hi, I was hoping someone could help me identify this necklace. I think it's mid-century Asian. It has metal that has been gold gilded or plated. None of the metal on the necklace is magnetic.

The smaller beads are made of glass and the larger pendant I think is some type of quartz. There is a chip in the large pendant stone on the side edge that is in a closeup in the 4th image which I've shown to help identify the stone.

Does anyone know anything about this necklace, perhaps how old it is, where it may have been made, where it may be from and the type of stone the large pendant is made from?

Thanks!
Kevin

 

The large "stone" also looks like glass,a photo of just the large"stone" might help a little.

 

I've added some more images. I think you may be right. Now that I've taken closeup pictures it looks like it could have been made out of glass. Thanks!

 

Stamped brass filigree and chain links (the chain is missing parts), along with the look of the glass, says 'Czech' to me...

Thanks Cheryl! I hadn't really noticed the missing parts on the chain, they were probably removed when glass beads broke. I didn't think about it being Czech, interesting. Would you think it's mid-century?
