Black Glass Crystal Octagonal Object Decor Paperweight

Add a touch of sophistication to your home with this elegant black glass crystal object. Its sleek design complements any decor style. New but has a few tiny scratches. The top brass part has started to tarnish. Honestly unsure what this is. Couldn’t find anything on it. Resembles vintage perfume bottles but I don’t see an opening. Could just be a paperweight.
