The monument comprises a well preserved standing stone, probably dating to the Bronze Age (c.2300 BC - 800 BC). It is situated within rough pasture on a slight promontory on the lower N-facing slopes of Cefn Du. The standing stone measures 1.8m in height, 1.2m in thickness from E to W by 0.8m in width; several packing stones are visible around its base. It enjoys excellent views to the N and W.

The monument is of national importance for its potential to enhance our knowledge of prehistoric ritual practices. The monument is well preserved and a notable local landmark, also forming an important element in the wider prehistoric funerary and ritual landscape. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The possible association of the standing stone with the nearby burial cairn (CN390) further enhances its importance.

The area to be scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 10m in diameter.
