Fake hallmark gold
With a fake hallmark gold, a silver 925 stamp on a gold-coloured object points to a silver alloy beneath the surface.
Contradictions in the stamp
Compare the fineness, office device and sponsor punch as a group. A mark reading 18K HGE identifies a plated layer, while PT950 belongs to platinum. A silver 925 stamp on a gold-coloured object points to a silver alloy beneath the surface.
What to check next
Record suspicious suffixes, mismatched metal words and any separate stamps on repaired fittings. Match the sponsor to its office and period. A jeweller’s assay checks metal content; a closer photograph helps resolve a worn digit or partly erased coating suffix.
