Five things we built because we kept doing them by hand. Everything runs in your browser. No photographs are uploaded, no data leaves the page, no email address is asked for.
- GuidedRead my hallmark Enter every mark on the piece and read it together: country, office, standard and, where the system allows it, the exact year. Nine countries, and it explains each mark on its own too.
- ReferenceSilversmiths directory One search across 45,000 makers from eight countries: name, initials, town or the device in a French lozenge. Registered years included, so a maker can date a piece.
- When the marks fail youDate your piece For pieces with no marks at all, or marks too worn to read. Answer what you can see and it returns an era, the reasoning behind it and the periods the evidence rules out.
- VisualCut comparator Drag between two diamond cuts drawn to real proportions and watch a century of technology happen.
