Ways You Can Tell a Diamond Is Real: Tips by Hatton Garden Jewellers

It might be difficult to tell if a diamond is real or fake, especially if you don’t buy from the best jewellers Hatton Garden or any other genuine dealers. It can also be hard to tell a real diamond in light of the abundance of high-quality imitations and synthetic stones. To help you out, here are trustworthy techniques to assist you tell the difference between a real and an imitation diamond.

The Water Test

The water test is one of the easiest and most reliable methods for evaluating a diamond. Compared to many imitations, including glass or quartz, which float or sink slowly in water, diamonds are dense and sink.

How to perform the test:

  • Tip in a glass of water.
  • Drop the loose stone into the glass with caution.

Interpretation:

  • The stone is probably a real diamond if it dips to the bottom.
  • It’s most likely a fake if it slowly sinks or floats.

2. Fog Test

If you walk into any shop such as the best jewellers Hatton Garden to find a diamond, you may want to do a fog test. The fog test makes use of the special heat-dissipating properties of diamonds. Because of their high thermal conductivity, diamonds can nearly instantaneously remove haze from breath.

How to perform the test:

  • Breathe on the stone by holding it between your fingers and inhaling deeply.
  • Watch how rapidly the mist clears. 

Interpretation:

  • The diamond is probably real if the mist disappears right away.
  • It is most likely a fake if the fog persists for a little while. 

Examine Under UV Light

When exposed to ultraviolet (UV) light, diamonds often shine. While fluorescence is a valuable indication, it is not 100% accurate because not all diamonds possess this property.

How to perform the test:

Put the diamond under a black light or UV light.

Interpretation:

  • Many diamonds will glow blue when exposed to UV radiation.
  • While a diamond may not always be phony if there is no reaction, it could be if additional testing yields negative results or if the stone changes color. 

Check for Imperfections with a Loupe

The best jewellers Hatton Garden’s loupe is a tiny magnification equipment that can be used to determine the authenticity of the stone in great detail. In actual diamonds, inclusions and imperfections are common small faults.

How to perform the test:

Examine the diamond’s outside and inside with a loupe.

Interpretation:

  • Since most natural diamonds have some blemishes, if you see small ones, the diamond is probably authentic.
  • Should the stone seem perfect (and it’s not a fancy diamond), it might be a fake or synthetic, similar to cubic zirconia. 

5. Conduct the Dot Test

The refractive qualities of a diamond, which affect how it bends light, can be ascertained with the aid of the dot test.

How to perform the test:

  • On a sheet of white paper, draw a little dot.
  • Over the dot, place the diamond’s flat side down.
  • Peer straight down through the diamond’s sharp tip.

Interpretation:

  • Because of the diamond’s high refractive index, if you cannot see the dot through the stone, it is probably real.
  • It’s likely a fake stone if you can see the dot or a circular reflection.

Conclusion

These techniques are not infallible, even though they can assist you in recognizing a real diamond. To ensure the authenticity of a diamond, it is best to have it assessed by a qualified jeweler or gemologist. To offer a conclusive response, they can carry out more sophisticated testing like X-ray exams or thermal conductivity tests. Still, these five tests provide a useful foundation for anyone wishing to independently confirm the legitimacy of a diamond.
