If you don’t want your gold item to get damaged:

  • Make a small scratch on your gold piece. If it’s a jewelry item, make sure the scratch is on the back side of it.

Results of The Vinegar Test:

After performing this gold test, you need to look for any color changes in your gold piece.

  • If it retains its color and lustrous shine, it is authentic gold. 
  • If it changes color and gets dark, it’s not real gold.

Vinegar changes the color of metals that are not real gold. You may see black or green color on fake gold bars. It can also damage fake gold jewelry. Different karats of gold have different reactions to vinegar. Most of the jewelry pieces are made of 10K or 18K. That is not pure gold. If you place them in vinegar, it can lead to permanent discoloration or damage.

Gold is a stable metal. Real gold doesn’t react to vinegar. Gold is also resistant to acetic acid, which is the key acid in vinegar. If your jewelry is made of real gold, it will not change its color. Rather vinegar cleans the gold and makes it shiny. When gold will not turn black, you’ll know it’s real. Mixing real gold with white vinegar is one of the best methods for testing gold. Vinegar will not harm gold in any way and real gold will not change color.

If there is a gold plate on your gold piece, the thin layer of gold comes off when you make a scratch. And when you add some drops of vinegar to that scratch, the underneath metal that is not gold will show discoloration.

If your piece is made of iron pyrite or chalcopyrite, it may retain its color. But you will notice crystals when it gets in contact with vinegar. There might be a bad smell too. 

If your piece is weathered mica, vinegar will remove the iron staining that gives it the look of authentic gold. Vinegar is a mild solution. So, this might be difficult to notice.
