If you have bought a diamond from an untrustworthy seller, and questioning if the diamond is genuine or not, this guide will provide you with some simple steps you may follow to test the diamond's authenticity.
A genuine diamond has high density, which is why the water test is a great method for analyzing the authenticity of a diamond. Put the diamond into a glass of water, if it sinks, it is a real diamond. If it floats, however, chances are it is a counterfeit.
The breathing test is another method for examining the authenticity of a diamond. Diamond is one of the best heat conductors. Therefore, when you breathe on a diamond, the fog disperses very quickly. When you breathe on a counterfeit diamond, though, the fog may remain for a few seconds.
Diamond is the hardest natural substance on earth, and it is incredibly resistant to heat. You may perform a heat test to check the genuineness of a diamond. Wear heat resistant gloves, hold the diamond with pliers, heat the diamond with a lighter for 30 to 50 seconds, and drop it into a glass of cold water. A real diamond will show no reaction, but a fake one is likely to get shattered.
The best way to check the authenticity of a diamond is consulting a diamond expert. A diamond expert has the professional tools and experience to give you the most accurate response.
