How to Tell If Old Jewelry Is Real Gold: Marks, Tests and Cautions
Tell if old jewelry is real gold by checking hallmarks, wear, weight, color, magnet limits, plating language, acid-test risks, and appraisal clues.
Need old jewelry checked before selling or testing it?
Upload hallmarks, clasp, back, stones, wear points, scale weight, measurements, boxes, receipts, and any repair history.
Start a jewelry appraisalThe quick answer
Look for a gold mark, inspect wear points, compare weight and color, check for plating language, and avoid destructive home tests. A magnet test or scratch test alone is not enough.
Gold triage checklist
- Marks: 10k, 14k, 18k, 22k, 375, 585, 750, 916, maker marks, and assay marks.
- Plate warnings: GP, GF, HGE, RGP, rolled gold, and gold filled are not solid gold marks.
- Wear: exposed base metal, flaking, green residue, and rubbed high points can indicate plating.
- Construction: clasps, jump rings, stones, solder, and mixed-metal parts can differ from the main body.
