Compare practical clues that can help distinguish solid-gold jewellery from gold-plated construction. Evaluate markings, visible wear, magnet response and testing evidence without treating any single clue as definitive.
Build a screening assessment from several independent clues.
Solid gold construction means the gold alloy forms the material through the gold-bearing structure. Gold-plated jewellery has a surface gold layer over another material. U.S. FTC guidance specifically regulates use of “gold plated” terminology and requires appropriate karat disclosure. 4
Plated surfaces can show a different underlying material where the coating has worn through. Check edges, ring undersides, high-contact points, clasp areas and heavily polished zones. Wear evidence is a clue rather than a laboratory test.
Strong attraction can raise a red flag, but non-magnetic behavior cannot establish solid gold. Clasps and springs can also contain different metals.
For high-value jewellery, combine construction inspection with density or specific gravity and, when warranted, XRF or laboratory analysis. A single home test should not be treated as definitive.
Gold alloy forms the gold-bearing structure rather than merely coating another core.
Gold or a gold alloy forms a surface coating over another material.
Use several independent clues: marks, construction, wear and testing.
Surface coatings can wear at edges and high-friction areas.
It can flag magnetic material, but cannot prove solid gold.
