Object type certainty: Possibly
Workflow
status: Awaiting validation 
A piece of black jet, or jet-like material, recovered and recorded because it is not naturally occuring in the area and may be an exotic material curated by human activity. As such, it dates from the Neolithic Period onwards. Worked flints have also been recovered from the location. The jet is not obviously worked or shaped, but has natural flat facets and what appears to be a conchoidal fracture. It is roughly a pointed oval shape and triangular in cross section. It leaves a dark brown mark on paper and is not cold to the touch. It is 56.6mm long, 29mm wide and 22.7mm thick. 13.9g. Compare SWYOR-1F0DD6.
