Vintage faux pearl choker

Vintage faux pearl choker, triple strand. The piece is quite heavy so I’m assuming the pearls are made of glass. Feels like pearls, not plastic. The three strands are stacked and aren’t tiered in length. Adjustable length: Shortest length is 13” longest length is 15.5”. You can see it was restrung at some point. Clasp appears to be brass. It could stand to be restrung.
