Identify Jewelry Pieces and Hallmarks

Identify an unknown jewelry piece by style and period, and read hallmarks to determine metal content, maker, and assay office.

Inherited jewelry, estate sale finds, and antique shop discoveries often come without documentation. Identifying a piece's era, style, and metal content requires specialist knowledge that most buyers, collectors, and even some resellers do not have.

Jewelry Visualizer analyses a photo to identify the likely style period, construction method, and any visible hallmarks — translating obscure assay marks, maker's stamps, and date letters into readable information.

Antique dealers use this to quickly research pieces before pricing. Collectors use it to authenticate family heirlooms. Estate agents and probate researchers use it to catalogue jewelry inventories accurately without specialist appraisal fees.
