Controlled Bubbles 6 Sphere Art Glass Orb Gazing Ball Paperweight. Pre-owned, very good condition, controlled bubbles art glass sphere with light sign of use or wear – one small fleabite nick near the top of the orb. The white marks are light reflections and any color spots you see are reflections and not in the glass. This is a heavy piece, as would be expected for the size. The bubbles have an intentional pattern. This is very nice quality with a cut off, polished bottom – with no apparent signatures. We do not know the maker or origin. Measurements – 6″ H x 6″ W x 6 D. Weight – 10 lb. I try to assess accurately… If you are unsure, please ask questions. And please inspect the photos.
