Could this be a Pearl?

A friend of mine was mixing sand for a golf coarse and found a five cm wide heavy white ball shaped object in the mix.
It seems to be solid white but has a very thin brownish stained coating that seems to be just on the surface. It seems to have been an almost perfect sphere except for one side is concave and some chips take out of the surface.
We believe the sand came from the Maine coast.
