The stone itself was modest in size, roughly half a metre long and a quarter of a metre thick, cut into a subrectangular shape from local granite. What made it curious was what was carved into its face: two lines of characters that resisted straightforward reading.

A 1931 account by Walsh recorded the inscription as something close to a bracketed arrangement of letters and numbers, with what appears to be the sequence ") M T (" on the first line and "171 ) 1V" on the second. Walsh interpreted these as possibly representing a builder's initials alongside a date, suggesting the stone may have marked the completion of some structure or commemorated whoever was responsible for it. The categorisation as "miscellaneous" in the 1986 Sites and Monuments Record reflects the difficulty of placing it neatly into any recognised type: it is neither a conventional grave marker nor an ogham stone nor a boundary post, but something in between, a small personal record in granite of a now-obscure act or person. The date encoded in the second line, if that is indeed what it is, would place the stone somewhere in the eighteenth century, though the precise year depends on how the numerals are read.

What adds a particular quality to the whole record is that the stone's current whereabouts are unknown. It was noted at its original location, described, and then lost to the historical record. Whether it was moved, built into a wall, or simply overlooked, the stone has not been formally located since. The inscription it carries may be the only surviving trace of whoever commissioned or carved it.
