Jewellery identifier · Experimental

Document the details of a jewellery piece.

Inherited and found jewellery often comes without information. We help you record the style, construction, stones and marks so you can ask better questions.

Tell us what you measured yourself, what someone told you, and what a report says — we keep these separate.

Questions

Can you date my piece?

We can describe stylistic features, but we cannot authenticate an exact date or maker from appearance.

Does a stamp prove the metal?

No. A stamp is a claim that can be wrong or forged; assaying tests the metal.

Can you value it?

We explain what drives value. A valuation needs an in-person appraisal.
