Big paperweight sphere in Portoro marble

Big paperweight with sphere shape in polished Portoro marble. Each piece is in a way unique (every marble block is different in veins and shades) and handmade by Italian artisans specialized over generations in processing marble. Slight variations in shape, color, and size are to be considered a guarantee of a handmade creation. It's important not to use lemon or vinegar on it, clean only with water and natural soap (like Marseilles soap), do not put it in the dishwasher.
