4. Weight and Density Issues

Weight Warning Signs:

  • Unusually light for its size
  • Inconsistent weight distribution
  • Hollow areas where solid gold should be
  • Feels plastic-like or too light

Expected Weights:

A 1cm³ cube should weigh approximately:

  • 24K Gold: 19.32 grams
  • 18K Gold: 15.5 grams
  • 14K Gold: 13.0 grams
  • 9K Gold: 11.5 grams

5. Magnetic Properties

Testing with Magnets:

  • Real gold is never magnetic
  • Strong attraction indicates fake gold
  • Slight attraction may indicate gold-plated items
  • Test multiple areas of the piece
💡 Pro Tip: Use a strong neodymium magnet for testing. Regular fridge magnets aren't strong enough for reliable testing.

6. Surface Texture Problems

Texture Warning Signs:

  • Rough or pitted surface
  • Bubbling or blistering
  • Seams or joining marks
  • Uneven wear patterns
  • Flaking or peeling

Common Counterfeit Textures:

  • Paint-like coating that scratches easily
  • Plastic-feeling surface
  • Powdery residue when rubbed
  • Bumpy or irregular finish

7. Chemical Reaction Signs

Watch for These Reactions:

  • Green or black marks on skin
  • Tarnishing or oxidation
  • Color changes with perfume/cosmetics
  • Reaction to household chemicals
⚠️ Important: Real gold is inert and doesn't react with most substances. Any chemical reaction is a red flag.
