Decorative spheres have a special place in the history of interior and garden design. We created the Gray & Silver Medium Sphere to not only add a storied shape to a space but a surprising hint of bling. Though the gray decorative balls are made of concrete, the asymmetrical application of a luminous silver finish over the raw gray surface shines when light strikes it. We also offer the silver decorative sphere in a small size, and we have gray and gold versions.
