The granite spheres can be made in sizes ranging from 300mm to 2500mm in diameter. A socket exactly matching the sphere diameter is cut and polished in the base rock.
The sphere and base can be machined and polished in stone of your choice, or you can select from our standard colours. Spheres can have their surface relief sandblasted and inlaid to produce a desired image.
Water pumped at low pressure is fed into the centre of the socket where it lifts the sphere. The water then either flows over the base, or into a channel and returns to the concealed pump pit. Even spheres weighing several tonnes can easily be turned by hand. The sphere is designed to continually rotate in different directions to keep it glistening wet.
The stone spheres are precisely machined to a perfect sphere and balanced on a machine developed and patented by Kusser Granit.
