It's a glass? necklace. I bought it a few years ago at a department store event. The faceted beads, like Czech beads, sparkle beautifully. I think it's glass, but as I'm looking at it closely now for the photos, it might be plastic? That's what it feels like. Also, if you look closely, the larger beads have some scratches. Please check the photos. As mentioned above, I'm offering it at a low price, so I'm looking forward to purchases from those who don't mind it being used. Color: Brown
