Green glass festoon necklace

The luxurious design of this necklace caught my eye at the thrift store, but I was surprised to find it was all glass instead of plastic which I had assumed. The main beads are a gorgeous shade of green (captured well by the camera!) and I like there's three different models of them. The clasp is a fish hook. No marks to identify the maker anywhere.

Unfortunately, because the necklace is composed of glass, it's heavy and well beyond what I can tolerate pressing down on my neck. None of my collars are helping, so it's been in storage so far.
