Note: Hammered copper ring made of roughly circular wire, probably from strip cut from sheet. Wire is roughly rounded with slightly flattened sides from hammering. Faint compression marks on inside and outside from earlier hammering into round stock. Evidnece of hammering on all four sides; more faceted ones on outside may be to shape the ring/opening area. Open ends are flattened; bit of a lip toward inner curvature but otherwise not granular; outer edges are not rounded or finished.
Treatment: Conservation Performed
Surface cleaned/degreased with acetone on cotton swab
