Methods to Identify a Real Diamond


Round Diamond Halo Pendant Necklace Diamonds are the most prized possession.   Whether loose or studded in jewelry they are loved and admired by people of all ages.   They are a beautiful accessory and a thoughtful investment.   It is therefore important to make sure that what you have bought is a real diamond and not the imitation crystal.
There are many traditional jewelers and reliable online retailers who provide an authenticity certificate along with the diamond jewelry.   But this is not a case with every shopkeeper.   If you are buying a ring or any diamond piece from a flea market or pawnshop or an antique store, you won’t get a certificate of purity along with it.   In such cases your investment on diamonds needs a much mindful decision.
Before stepping further in buying, it is better to check if the piece of stone you are paying for is real or just a fake crystal.   After all it’s a matter of your hard earned money and the sentiments associated with your buying.
There are few methods you can use to test the stone.   Many of these tests are easy and very handy which could be instantly performed by anybody.   Though they are not very authentic yet they help in differentiating a real diamond from a fake one.
Other methods that test a diamond are more professional.   They are used by certified jewelers and gemologists who have years of experience and eagle eyes that can catch the real diamond instantly.
Here are few tests you can conduct on your own to judge the real diamond.

Reading Test

It can be done in case of a loose diamond.   Flip the diamond upside down and place it on a printed paper.   Now see if you can read the words through the stone.   If the words are clearly readable then the stone is a fake stone.   A real diamond due to extra brilliance doesn’t allow the eyes to read the words through it.
Note: Many diamonds are shallow cut and allow reading through them.   This doesn’t mean they are not real.   So it is better not to completely rely on this test to justify the answer.

Fog Test

Hold the stone in front of your mouth and fog it as you fog a mirror.   If it stays fogged for few seconds, it’s a fake diamond.   Real diamond instantly disperses the heat and remains clean and bright always.
Note: If the diamond has dust and dirt film on it, it won’t disperse the heat and would stay fogged, resulting in misinterpreting it as a fake stone.   It is suggested to properly clean the diamond before performing this test.

Weight Test

Get a CZ of the same size, shape and dimension as your diamond has. Put both the stones in a gram measuring scale and check which weighs more. CZ weighs 55% more than diamond of the same dimensions. So if you are given a real diamond it would weigh less on the scale.

UV Light Test

Examine your stone under UV light. If it is giving blue fluorescence chances are that it might be a real diamond but of lower quality because diamonds that exhibit blue fluorescence are less valued than their counterparts. If the stone displays yellow or green fluorescence, than it is probably a Moissanite.
Note: The higher quality diamonds don’t exhibit blue fluorescence so the test may create confusion.

Reality Checkpoints

  • Get a combined Diamond/Moissanite tester that quickly indicates if the stone is a real diamond or a fake crystal. Diamonds and Moissanite have almost similar thermal conductivities so a combine tester is better than individual ones.
  • If it is a diamond jewelry piece then carefully check the mounting and setting. Diamonds being so precious and valuable are always fixed in precious metal.
  • If it is a real diamond it will reflect various shades of grey.
  • If the diamond is real then you won’t see the bottom of it from viewing the top when it is mounted.
  • If the stone is showing double reflection, it is probably a Moissanite which is so identical to diamond that only experts could differentiate it.
  • These are the few most common tests you can conduct to judge if what you are buying is a diamond or anything else. Once you are a bit satisfied about the stone get it checked by a certified appraiser or gemologists who will not only provide you with the authenticity of your piece but would also evaluate its worth. Also get your diamond registered and fingerprinted so no one would exchange it at your back.
