The geochemical assay reveals elevated nickel (7.80%) and cobalt (0.48%) yielding a diagnostic Ni/Co ratio of 16.25, falling decisively into the octahedrite meteorite domain (Groups IAB/IIIAB). Metallographic simulation indicates preservation of kamacite/taenite Widmanstätten lamellae with cold-hammering slip lines, confirming the ring was formed via non-thermal artisan forging before terrestrial smelting emerged in the Aegean.
