This intricately decorated black stone ball was found in Aberdeenshire, Scotland.
The carved ball has an average diameter of 73mm and weighs just over 500g. It dates back over 5000 years and has four discs or knobs, of which three are intricately carved and the fourth is blank.
Over 400 carved stone balls are known, mainly from Scotland, made from a variety of stone. Few have archaeological contexts and their purpose is still unknown.
