This is a natural stone that my grandfather collected. The round ball is 2.5 kilograms and is quite large and heavy. The stand itself is also made of natural stone. The last photo is of the underside of the stand. There is some dirt on the underside, but it's not visible, so it might be a good deal for someone who doesn't mind. Weights are approximate. Round ball weight: 2.5kg Stand weight: 6.8kg We have various other items as well. Please take a look if you're interested.
