My dad found this unusual stone many years ago whilst strolling along a beach on the South Coast of England (he can't remember which one). It's made up of three smooth spheres that appear to have been fused together. The stone is lighter along the joins and they have a sandy texture. My dad thought it was a lump of old iron, but it is not magnetic and not as heavy. I was wondering if anyone out there might know what it is and how it came to be on the South Coast.

Many Thanks!

Paul.
