Amid the five surviving uprights and fallen stones of what was once a nine-stone ring, a single block of quartz has been placed at the heart of the circle, aligned precisely along the same north-north-east to south-south-west axis that governs the whole structure. Quartz appears frequently at prehistoric ceremonial sites across Ireland, and its placement here, central and intentional, suggests it was no afterthought.

The circle at Templebryan sits on level ground in rolling pasture, roughly 500 metres south of the Argideen river. Of the original nine orthostats, the large upright stones that form the ring, four remain standing and one has fallen. The survivors range from around 1.4 to 2 metres in height, and the internal span of the circle along its main axis measures approximately 9.5 metres. Among the standing stones are what may be the axial stone and the entrance stones, features typical of the Cork-Kerry stone circle tradition, where a recumbent or low stone marks one end of the axis and a pair of taller portal stones frames a formal entrance on the opposite side. The quartz block itself is modest, 0.8 metres high and roughly 0.9 by 0.7 metres at its base, but its positioning along the same NNE-SSW alignment as the wider structure points to a carefully considered prehistoric arrangement. The site is noted in Ó Nualláin's 1984 survey of Cork stone circles and in Roberts's 1988 study.
