While it is obvious the blue sapphire prices of natural stones are higher compared to synthetic and imitation ones, many dealers and jewellers can try to con buyers can sell you fake blue sapphire gemstone or try passing you synthetic or imitation blue sapphires as natural ones.

Here are some simple tricks to identify natural, synthetic and imitation blue sapphire gemstone.

  • Lookout for Scratches

Blue sapphire gemstones are highly durable and are considered as one of the hardest gemstones after diamonds and cannot get scratched easily. You can try rubbing the blue sapphire gemstone against a rough surface and look out for scratches. It is obvious to state that genuine blue sapphire stone will not have scratch marks while a fake one will.

  • Lookout for Flaws

It is extremely rare to find natural blue sapphire gemstone without any flaws or inclusions. Natural gemstones have minor traces of foreign matter bounded within the stone and hence a perfect blue sapphire stone is probably a synthetic and not a natural one. This can be done using a jeweller’s loupe or a magnifying glass to detect any visible impurities or flaws within the gemstone.

It is vital to check the origin for the gemstone as blue sapphire prices tend to be higher for the natural blue sapphire gemstone.

  • Look out for Line or Bubble Inclusions

While checking out for flaws in a blue sapphire gemstone, it is also vital to look out for line and bubble inclusions within the gem. You should inspect the gemstone from all possible angles for the existence of air bubbles, as these might be visible from only a certain angle.

In case you find any line inclusion or air bubbles in your gemstone, it is probable that the blue sapphire stone is made of glass or some form of composite sapphire.

  • The Breathe Test

The breathe test is a relatively simple and basic test used to investigate the genuineness of the blue sapphire gemstone. When you blow on a gemstone, a layer of most or fog forms over it. If this misty and foggy layer evaporates within a matter of a couple of seconds, the probability of the Neelam stone being genuine are high and fake knockoff can take 5 seconds or more for the misty layer to evaporate. This is due to the blue sapphire stone is a warm stone and naturally conducts heat.

  • Consult a Reputed Gemmologist

This gemmologist can also offer you a certificate of authenticity in case you don’t have one.
