Very nice! Problem is it could be deco or it may be as new as 1990s. There are no tell- tell age signs from this necklace other then the cut of the glass rhinestones a close up would give a hint. Also put the green stones up against your face to find out if the stones are glass or real. Ice cold is real, cool then warms up is glass.Someone else may recognize it tell who actually made the piece.
