Quick Answer

How can you tell if gold is real?

To determine if gold is real, you can perform these 4 reliable tests:

  • Hallmark Check: Look for stamps like "585" (14K), "750" (18K), or "999" (24K)
  • Magnet Test: Real gold is not magnetic - if it sticks to a magnet, it's not pure gold
  • Acid Test: Professional testing using nitric acid to verify gold content
  • Density Test: Pure gold has a density of 19.32 g/ml at room temperature

💡 Professional Tip: The hallmark test is the most reliable method for consumers to verify gold authenticity without professional equipment.

Don't risk buying fake gold. Learn these simple tests to verify authenticity.

Common Tests for Gold Authenticity

  • The Hallmark Test: Look for official stamps indicating purity
  • The Magnet Test: Real gold is not magnetic
  • The Acid Test: Professional method using nitric acid
  • The Density Test: Comparing weight to volume ratio

Detailed Testing Methods

1. The Hallmark Test

Look for stamps like "585" (14K), "750" (18K), or "999" (24K). These numbers indicate gold purity. Authentic pieces will have clear, precise markings.

2. The Magnet Test

Use a strong magnet - real gold is not magnetic. If your piece is attracted to the magnet, it's likely not pure gold. However, note that some gold alloys might show slight magnetic properties.

3. The Acid Test

This should be performed by professionals. A small amount of nitric acid is applied to determine gold content through chemical reaction. Different reactions indicate different levels of purity.
