The stone is sub-rectangular in shape, roughly 0.97 metres high and 0.6 metres across, and its long axis runs on a southeast to northwest alignment, which may or may not be coincidental but is the kind of detail that tends to linger in the mind.

Standing stones of this type are found across Ireland in considerable numbers, and while individual examples are rarely datable with precision, most are thought to belong broadly to the Bronze Age, somewhere in the period between roughly 2500 and 500 BC. What makes the Sarsfieldscourt stone worth pausing over is its relationship to the surrounding landscape. About 120 metres to the east, on the same east-facing slope, there is a levelled circular enclosure, the kind of low, worn earthwork that could represent a ring barrow, a burial monument, or a small enclosed settlement depending on what lies beneath the surface. Whether the stone and the enclosure are directly connected is unknown, but their proximity on this shared slope suggests they were part of the same inhabited or ritually active territory, people over generations marking the land in ways whose logic has long since become opaque to us.
