We tell you seven ways to spot a real diamond…from a fake

A recent story emerged that a diamond bought for £10 at a car boot sale 30 years ago will auction at £650,000.

So we found an article telling you seven ways to spot a real diamond from a fake…

1. Thermal conductor Diamonds are excellent thermal conductors, so will be cold to the touch. A fake diamond will be room temperature.

2. Line test For rounds, draw a black line on a white piece of paper and turn the diamond upside down, with its table (the flat top part) facing down. Move the diamond back and forth over the line. If you can see the line through the diamond, it is fake.

3. Inclusions Many lower quality diamonds will have a small visible inclusions (particles inside that look like dirt). If you can spot something like this inside, it may be a good indicator that the diamond is real.

4. Sparkle A real diamond will sparkle more than a fake. This is not the most accurate test, but will catch poor quality fakes.

5. UV light About 50 per cent of real diamonds will fluoresce or glow blue under Long Wave UV light. If the diamond doesn’t glow, it is an indicator it may be fake.

6. Laboratory The most definitive way to determine if a diamond is real, is to send it off to a credible laboratory like the GIA (Gemological Institute of America), which will not only determine whether it is a real or fake diamond, but can determine if it is man made, has been treated with heat / pressure or is 100 per cent natural.

7. Diamond tester You can buy a diamond tester for about £300-400 which will tell you if the stone is a real diamond or a simulant (like cubic zirconia or moissanite).

…So now you know!
