Can you authenticate a Cartier Love bracelet?

Yes. Love bracelets are among our most requested items. We inspect hallmarks, screw mechanism, weight, and serial details and advise when box and papers alone are insufficient.

Do you test if gold is real?

We verify hallmarks, construction, and brand authenticity. Acid or assay testing for unbranded gold may need a separate assay service; we tell you when that applies.

Can I authenticate a Tiffany necklace from photos?

Clear macro photos of stamps and clasps help for an initial view, but many Tiffany fakes need physical inspection. We guide you through secure posting when required.

Jewellery Authentication Service

Jewellery counterfeits copy hallmarks and packaging well enough to fool casual buyers. Our authentication inspects stamps, engravings, weight, clasp mechanisms, and brand-specific details on Cartier, Tiffany, and fine jewellery, with certificates for gifts, resale, and insurance.
