It's a brooch with a hook in back so it's also a pendant and I added the chain which is vintage. The brooch pendant is lightweight silvertone filigree. All stones are glass. The pin looks askew but it's not! Closes with rolling safety catch. It's a bit "loose", which just means that it's 3 layers and the top 2 layers turn.
Oh and did you know all the fun things you can do with a brooch that's a pendant on a chain? Check all photos and you will see some ideas.
Ruler shows size. Will come in a gift box.

This item is sold from an excellent, highly rated vintage boutique in Northfield, OH.
