The biggest mistake of my professional career was related to a Pacific & Co. piece that was thought to be gilt by everyone (including the consignor, who taught metallurgy at the collegiate level and was renowned in his field) but was actually gold.
SG is your friend, young Jedi. Density solves mysteries.
How could a renowned metallurgist make such an amateurish mistake?
Did he not do any nondestructive elemental tests on it? E.g. specific gravity, X-ray fluorescence (XRF), Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS)
