Historical French mark for high-quality gold-filled jewelry produced by the FIX company, mid-20th century. Sometimes confused as a generic mark; actually a brand reference.

How to check it yourself

  1. Examine the stamp under a 10× loupe — genuine marks are crisp and evenly struck, not doubled or smeared.
  2. Confirm the mark reads FIX or an equivalent such as FIX OR.
  3. Photograph it in the Jewelry Identifier app to read the metal, hallmark, and any gemstones from the image.
  4. For a binding result, have an assay office or gemological lab run an XRF purity test.

FAQ

Q. Is FIX the same as FIX OR?
A. Yes. FIX, FIX OR all denote the same material — gold-filled. Different markets and eras stamp it differently, but the purity is identical.
Q. How do I confirm a FIX stamp is genuine?
A. Look at the mark under 10× magnification for crisp, even strikes, cross-check the weight-to-volume ratio against the expected density, scan it with the Jewelry Identifier app, and — when it matters — have an XRF test done by an assay office or gemological lab.
