NWOT large grey crystal necklace

Fabulous crystal necklace Dark grey, light grey and black on a dark grey chain There are really 2 layers of crystals, the briolettes hang from the back layer and the flowers are on top, so it has a lot of depth It is about 2.5" wide in the middle. The chain is about 17" with a 5 inch extender Not sure what kind of crystal but they are quite pretty and sparkly. New without tags, never worn This is a pretty heavy necklace, probably not for a petite person I have a smoke-free pet-free home and use recycled materials where possible.
