Amgueddfa Cymru
A perforated stone disc made of extremely fine-grained altered igneous rock which has weathered to a light green-brown colour. The stone has a centrally pecked hour-glass perforation and its entire and nearly circular perimeter has been ground to an edgem from both faces, presenting an angled 'blade' of between 70 and 90 degrees. Both faces are smooth and probably consist of a natural pebble surface, whilst the edges clearly preserve the traces of a concentric grinding. The implement is scarcely damaged and has no obvious signs of functionally related use-wear.

Nodiadau: Note that in the excavation seasons 1980, 1981 and 1982 the X axis was numbered alphabetically and the Y axis numerically. In 1986 this was reversed in error resulting in the X axis being numbered numerically and Y axis alphabetically. All the finds were marked during the excavation so are marked by grid square using the site system that was in place at the time. The 1986 finds coordinates have not been corrected.
