Purchasing a diamond for yourself or a loved one is a special moment.  Unfortunately, some in the diamond jewelry business will use the excitement you feel to take advantage of you when your guard is down.  At Primestyle.com not only are we committed to providing you nothing but the best in authentic diamond jewelery – we are also committed to making sure that any time you purchase a diamond you are able to do so confident that you have received the true, authentic gem that you expect.

Not everyone can be a trained gemologist.  But don’t worry!  In order to keep your special moment from turning into a nightmare, we have compiled a list of ways you can test whether any gem is an authentic diamond or a fake.

Here a few tips and tests that anyone can use to make sure that you protect yourself from unscrupulous diamond sellers:

1.  The “Fog” Test

To perform this test simply breathe on the diamond in order to see how much condensation builds up on its surface when your breath hits the stone.

Unlike glass, cubic zirconium, quartz, or leaded crystal, diamond is an extremely strong and durable stone.  This means that breath “fogging” onto the diamond (like a mirror would in a room filled with steam) is a telltale sign that your “diamond” is really a fake.  A true diamond will not allow any condensation to lie on its surface for any amount of time.

2.  The “Writing” Test

Even though the clarity of a diamond is one of its most important attributes, a true diamond will never be transparent.  So for this test, simply take a piece  of paper with writing on it (a newspaper is the most common example) and place the top of the gem (“table side”) on top of it.

The clarity of a synthetic stone will cause it to act like a magnifying glass, allowing you to read the text from the paper straight through it.  In contrast, an authentic diamond will reflect so much light that it will be impossible for you to even see the text on the other side.

3.  The “Reflection” Test

Because the inside of a diamond is so intricate, examining how light acts as it passes through the gem that you are trying to authenticate is also a good way to test if it is a real.  When held up to light, the facets within a real diamond will cause shades of grey to appear within them.  A synthetic diamond however will refract the light into a rainbow.

4.  The “Scratching the Glass” Test

One final test you can do is the one commonly shown in the movies – taking the diamond and scratching a piece of glass with it.  Although this is not recommended (for both the sake of the glass and the fake gem), nevertheless it is in fact a reliable test and will easily indicate if the stone is a real diamond or not.

5.  A Professional Appraisal

In the end, the only way to be 100% certain that a suspect gem is real is to bring it to a reputable jeweler and have it authenticated.  When choosing a jeweler, make sure it’s someone who has all the tools and equipment necessary to do a proper verification.  Even more importantly, be certain you can trust the person or business you bring the diamond to to be honest with you.  A dishonest jeweler could defraud you by telling you a fake diamond is real.  Finally, if you feel a jeweler may be lying to you, never hesitate to go and get a second opinion.

    We would recommend you taking your diamond to a 3rd party appraiser and have them appraise it for you. This is the best way to properly determine what time of diamond you have and gain information on all specifications of the diamond you have including the cut, color, clarity and carat weight.

    All of your tests are totally unreliable and inaccurate. You are giving the public inaccurate information. The only good point was the last one advising people to get a professional appraisal.

      With the exception of a professional appraisal, no, none of these other methods are at all scientifically accurate. They are common, very basic methods used by the layperson but, as we mention in the post, only a professional appraisal can ever be completely accurate

    looking into a princess cut 2.03 ct wt white stone, it is impossible to see through while looking through the pavilion. however, looking strait down into it from directly above, it is not as it is as seen through the side of the pavilion; it’s no longer reflective as it was as seen looking through the pavilion from an angle. it’s a square princess cut, not a round brilliant cut. it has four large pavilion facets, with the “cutlet” being the facets from the four corners to the point of the cutlet. so looking through this stone should be remarkably different than gazing into the pavilion/cutlet of a round brilliant to see the possibility of reading print or a dot from various angels through the pavilion vs directly down into the cutlet. only at an angle through the pavilion is there absolute reflection making print impossible to see. however, looking down directly from above, strait down into the tip of the cutlet is what ever the table of the stone resting upon visable. in addition, under UV light it appears nearly inert with the exception of refracted UV light intensified within the stone- emitted through a facet after it reflects off facet angles within the stone and comes out through a top/ edge facet next to the table with a blue color, not violate, but blue. as if the luminescence is so faint, it is “gathered” by internal multiple reflection/refraction and emitted as an intensified blue through a small top facet. any gemologists out there have any opinions on the identity of this stone based on what I have shared here?????
