It’s a decorative household item, looks to be made of brass and colored glass with a marble base. It is about 2’ high, and has no lamp wiring, or signs that it ever had wiring in it. It does appear to look like a set of scales, but has no moving parts, and I would think that putting uneven weight on the arms would cause it to tip over.
Non-functional replica of a scale. If you look at the top, there is a vertical needle that, in a functional scale, indicates right or left. There were probably hanging bowls for display of wax fruit, or perhaps plants.
Missed the edit window, but it’s definitely a decorative scale. When it had the hanging baskets, you probably had to be careful about what you put in it. Try an image search of “decorative scale” and you’ll see many similar ones like this.
