The purpose and meaning of the stones are still unknown, but they probably served as a indicator for clans, lineages, or kindreds. It is probable that they honored individuals as a kind of grave stone. The symbols could also have been some kind of pictographic system of writing. The symbols can also be found on jewelery.
Classification
Pictish stones conventionally are divided into three groups:
Class 1 — unworked stones with symbols only incised. There is no cross on either side. Class 1 stones date back to the 6th, 7th and 8th centuries.
Class 2 — stones of rectangular shape with a large cross on one side and symbols on the other. The symbols, as well as Christian motifs, are carved in relief and the cross with its surroundings is filled with designs. Class 2 stones date from the 8th and 9th centuries.
Class 3 — on these stones no Pictish symbols can be found. The stones can be cross-slabs, recumbent gravemarkers, free-standing crosses, and composite stone shrines. They originate in the 8th or 9th century.

Pictish symbol stones are generally found in the north-east of Scotland, with clusters found along the eastern coasts and into the Highlands.
At Burrian in Harray an incised cross was found along with an impressive eagle, similar to the one carved on the standing stone at the Brough o' Birsay, a crescent and V rod and mirror symbols.
This stone fragment was found to be decorated with a rough double-disk symbol and dates from the middle of the sixth century.
The purpose and meaning of the stones are still uncertain, but they probably served as personal memorials, the symbols indicating membership of clans, lineages, or kindreds.
