Come on then, enlighten me. Why is this stone black?
It has not been painted, more like stained, as it still shows the natural grain of the stone.
Anyone else know of one similair?
My theory is that it is caused by the oils fom the sheep wool as they rub against it, but then it would'nt be on the top of the stone as well, would it?
