The Carved Stone Balls are mysterious objects and they have been the subject of much speculation by scientists over the years.
Over 400 of these unique objects have been found, nearly all of them in the Scotland, with the majority found in Aberdeenshire, however, some samples were also discovered in Britain and Ireland. The stone balls date from about 3500 to 1500 BC, a period spanning between the later Neolithic era and the Bronze Age.

All the stones are made of various different materials ranging from sandstone to granite and they are all decorated with knobs around the surface. The numbers of knobs range from between three and 160 but the most common ones are those with six projecting knobs.
Some carved balls have additional decoration, such as in the spaces between the knobs which are decorated with hatchings, incised lines, spirals and concentric circles. Most of the stones are of a similar size with a diameter of 3 inches, although some larger ones were found, ranging from 3.5 and 4.5 inches.
