An antique French metric ring sizer used by jewelers to measure finger sizes. The plaque reads "Baguier Métrique Déposé," which translates to registered metric ring sizer. The stamped numbers (like 50, 55, 60) represent the inner circumference of the ring in millimeters.
This antique French ring sizer dates to the late 19th to early 20th century, specifically the 1890s to the 1920s. The Term "Déposé" means "registered" or "patented" in French. It began appearing heavily on tools, jewelry, and toys after France updated its trademark and design protection laws in the late 1800s.
The heavy, flat-band steel rings and the stamped font style on the identifier tab are classic hallmarks of French industrial and jeweler tool production from the Belle Époque and early Art Deco eras. This item retains its original identifier tab, lacks any visible rust, and appears to have a complete set of rings. It is perfect and in mint condition.
