Method
The same details a trained jewellery historian would examine — evaluated in seconds.
Photograph
Capture the hallmark, maker's punch, clasp mechanism and overall form. A macro shot of any marks alongside a full piece view gives the best results.
Visual comparison
Your image is matched against a curated corpus of jewellery references from auction catalogues, specialist publications and museum collections spanning two centuries.
Feature analysis
Key identifying characteristics are scored: hallmark type, setting style, stone cut, mounting technique, decorative motifs and period indicators.
Identification
A ranked list of probable matches is returned with maker, period, style, country of origin, and the features that led to the identification.
Coverage

FAQ
CaratID covers antique and vintage fine jewellery from approximately 1800 to 1950 — including Georgian, Victorian, Edwardian, Art Nouveau and Art Deco pieces in gold, silver and platinum.
CaratID uses AI trained on thousands of documented hallmarks and maker's punches from British, European and American assay offices. Accuracy is highest for British hallmarked pieces. Results should be verified by a trained jewellery specialist for high-value items.
CaratID identifies stone cuts, settings and likely gem species based on visual analysis. Laboratory gemological testing is required for definitive gem identification and certification.
For hallmarks, use a macro lens or close-up mode in good raking light to reveal stamped details. For the full piece, photograph on a neutral surface in diffuse daylight to capture true colour and form.
