Collected along the wave‑polished pebble line. The piece shows uniform deep red colouration with occasional darker mottling, consistent with hematite inclusions in chalcedony. Fresh chip displays a clean conchoidal fracture and vitreous lustre.
Field tests: copper does not scratch; scratches glass; white streak on unglazed porcelain. Identification consistent with red jasper (a variety of microcrystalline quartz).
