Simple Tests You Can Do at Home
1. The Water Test
What You Need: A glass of water.
How to Do It:
- Fill a glass with water.
- Drop the diamond into the glass.
Result:
- Real Diamond: Sinks straight to the bottom.
- Fake Diamond: Floats or sinks slowly.
💎 Diamonds are dense, which is why they sink!
2. The Fog Test
How to Do It:
- Hold the diamond between two fingers.
- Breathe on it to create fog.
Result:
- Real Diamond: Fog disappears almost instantly.
- Fake Diamond: Fog lingers for a few seconds.
Why? Diamonds disperse heat quickly, so fog won’t stay.
3. The Transparency Test
What You Need: A newspaper or paper with printed text.
How to Do It:
- Place the diamond flat side down on the text.
- Try reading the letters through it.
Result:
- Real Diamond: You can’t see the text clearly.
- Fake Diamond: The text remains visible.
💡 Diamonds bend light, making it hard to see through them.
4. The Sparkle Test
How to Do It:
- Hold the diamond under a bright light.
- Observe its sparkle and reflections.
Result:
- Real Diamond: Shines brilliantly, with white and rainbow sparkles.
- Fake Diamond: Dull with less brilliance.

2. Use a Diamond Tester
What Is It? A handheld device that checks thermal conductivity.
How to Do It:
- Place the tester’s tip on the diamond.

- Fake Diamond: No reaction or a different signal.
3. Professional Appraisal
