Top Five Methods to Test Gold Purity at Home

1. Magnet Test

Hold a strong magnet close to your gold item. Genuine gold is not magnetic, so if the item sticks to the magnet, it’s likely not pure gold or could be a gold-plated item with other metals inside.


  • Obtain a strong magnet.
  • Hold the magnet close to your gold item.


  • No attraction: Genuine gold.
  • Attraction: Likely not pure gold or gold-plated with other metals inside.

Why It Works: Gold is not magnetic, and most metals used to alloy gold (like copper and silver) are not strongly magnetic either. If the item reacts to the magnet, it indicates the presence of other, less valuable metals.

2. Float Test

What You Need: A glass of water.


  • Fill a glass with water.
  • Gently place your gold item in the glass.


  • Sinks to the bottom: Pure gold.
  • Floats or hovers: Likely not pure gold.

Why It Works: Gold’s high density (19.32 g/cm³) ensures that it will sink in water. Impurities or lighter metals mixed with gold may affect its buoyancy.

3. Skin Test

What You Need: Your skin and a bit of time.


  • Wear the gold item for a day or two.


  • No discoloration: Pure gold.
  • Greenish tinge or discoloration: Likely contains other metals.

Why It Works: Pure gold is hypoallergenic and does not tarnish or react with skin. Discoloration indicates the presence of other metals like copper or nickel.

4. Vinegar Test

What You Need: White vinegar.


  • Obtain white vinegar.
  • Place a few drops of white vinegar on your gold item.


  • No color change: Genuine gold.
  • Color change: Likely not pure gold.

Why It Works: Gold is a stable metal and resistant to corrosion and chemical reactions. Vinegar is acidic and will cause base metals to react and change color, but it won’t affect gold.

5. Nitric Acid Test

What You Need: Nitric acid (available in jewelry supply stores), a small glass bowl, and protective gloves.


  • Buy a gold testing kit that includes nitric acid.
  • Scratch the gold item on a testing stone.
  • Apply a small drop of nitric acid to the scratched area.


  • No reaction: Genuine gold.
  • Green reaction: Base metals.
  • Milky reaction: Gold-plated sterling silver.

Safety Note: Nitric acid can be dangerous; it is advised to use gloves and safety eyeglasses while handling the substance.

Caution: The Nitric Acid Test can damage your jewelry, especially if it is not pure gold. Use this method with caution and consider having a professional conduct the test to avoid any potential harm to your item.
