Why Some People Use Toothpaste to Test Gold
Toothpaste is sometimes suggested as a quick home check for gold. The idea is that real gold should not react with the mild abrasives in toothpaste, while fake gold might show a mark or discoloration.
How to Perform the Toothpaste Test
Place a small drop of white, non-gel toothpaste on a clean, soft cloth or directly on the gold. Gently rub the paste over the surface for a few seconds, then wipe it off with a damp cloth. Check the area for any dark residue or scratches.
What the Results Mean and When to Get a Professional Test
A clean surface with no visible marks may suggest the item is gold, but this test is not definitive. Toothpaste can scratch soft metals and may not reveal plated or alloyed pieces. For reliable results, consult a jeweler or use a certified testing method from a trusted source like Gemological Institute of America.
