Color and Appearance
- Pure gold has a rich, warm yellow color
- Should not have any green or black spots
- Surface should be uniform and smooth
- Watch for any color variations or wear
Hallmarks Guide
| Mark | Meaning | Gold Content |

| 750 | 18 carat | 75% pure gold |

2. The Magnet Test
What You'll Need:
- Strong neodymium magnet (regular fridge magnets aren't strong enough)
- Clean, flat surface
- The item you want to test
Testing Process:
- Place your gold item on a flat surface
- Hold the magnet close to the item (without touching)
- Observe any attraction or movement
- Test multiple areas of the item
💡 Pro Tip: Real gold is not magnetic. If your item is strongly attracted to the magnet, it's likely not gold or has minimal gold content.
3. Size and Weight Test
Gold is a dense metal, making weight a good indicator:
- Gold feels heavier than similarly sized items
- Weight should be uniform across similar pieces
- Compare with known genuine gold items
- Check for unusual lightness or weight variations

Method:

- Observe the color of the streak left behind
- Real gold leaves a golden streak
⚠️ Warning: This test may leave a small mark on your item. Test in an inconspicuous spot first.
