That is more or less the entire situation, and it is worth pausing on, because it captures something genuinely common in Irish archaeology: the object that was recorded, catalogued, and then quietly slipped out of reach.

A bullaun is a boulder or large stone into which one or more cup-shaped depressions have been carved or worn, most likely through repeated grinding. They appear throughout Ireland, often near early ecclesiastical sites, and their precise function remains debated. Some were probably used for grinding pigments, grain, or medicinal herbs; others may have had ritual significance, and many are associated with holy wells or early Christian enclosures. The Labanasigh example is granite, which is notable in itself, since granite is a harder and less easily worked material than the sandstone or limestone more commonly shaped in this way. It was found built into a wall, which suggests it had already been displaced from whatever original context it once occupied, incorporated into later field or boundary construction in the way that inconvenient large stones so often were. Beyond that, local information recorded prior to 1993 placed it somewhere in the locality, but subsequent attempts to confirm its whereabouts have come up short.
