Poincon de sablier avec les lettres FNB entoure d’un border

Illustration of the hourglass hallmark with the letters FNB (for Fabrique Nationale de Besançon) surrounded by a border

Hourglass hallmark with the letters FNB (for Fabrique Nationale de Besançon), the whole surrounded by a border. For watchmaking in Besançon, large works in 750/000 gold or 800/000 silver. Besancon 1800-1821.

The information about the hourglass hallmark with the letters FNB and the other illustrations of hallmarks on this website come from the book Traditional French Jewellery, written by Mike Fieggen, expert in antique jewellery and hallmarks from Osprey Paris. This 300-page book, the definitive reference on French regional jewels and their hallmarks, is available in French and English in our store, on Amazon and at certain bookshops. A complete list of assay office marks, small secret marks in the hallmarks that allow you to identify in which city an object was hallmarked, as well as a list of the closing dates of the hallmark offices, are published in this book for the first time. You can thus locate the origin of the jewels and also date them with more precision.

Every day we sell new and used jewellery at unbeatable prices, we NEED merchandise every day.

Don’t even think about selling your jewellery in auction rooms, or at gold buying pharmacies, the “cowboys” that do so much harm to our profession. Instead, visit real professionals for an honest and clear service of buying gold in Paris.
