There may be a risk that the diamond in that jewelry is false, so the surprise may be bitter if this unfortunate event occurs. If before going to the jewelry store you are looking for how to know if a diamond is real, don’t worry, here we will describe 7 effective ways that answer how to Identify a real diamond so that you avoid an unpleasant moment when buying or acquiring these precious stones. But first, we will describe to you what a diamond actually is. It is a precious stone formed by pure crystallized carbon, resulting in a mineral that is the clearest, hardest and most brilliant of all.

Appreciate the characteristics of a genuine diamond

Before submitting the diamond in question to a home or professional test, there are certain elements that characterize this stone and that are noticed just by looking at the jewel, aspects that help answer how to identify a diamond.

Among the features that can solve the doubt about how to identify a diamond with the naked eye are:

Hardness

Let’s remember that diamond is the hardest mineral, so when you take it, you can scratch any other surface with it or even cut other materials.

Endurance

In addition to being hard, diamond is resistant, a factor that allows it to be safe from any damage that can be caused by high temperatures.

Bright

Another aspect to consider when answering how to know that a diamond is authentic is the extraordinary brilliance that characterizes this mineral. You must take into account that the brilliance of a diamond is greater than that of a quartz or a crystal, so follow this reference when you know what real diamonds are like.

In addition, the reflection of light caused by the shine will depend on the cut or cut of the diamond, which must be proportionate and symmetrical and which, to add, is a factor that allows determining the quality of the jewel.

Transparency

Are you looking for how to know if a diamond is genuine? You should pay attention to this aspect, since, contrary to what is believed, a diamond is not completely transparent when compared, for example, with a zircon.

Knowing the clearest physical characteristics that can help you verify what a diamond is like, now you can subject this jewel to the following tests to verify its authenticity.

Water test

If you are looking for how to know if a diamond is real at home, you can do this simple test to verify. Fill a glass with water until it reaches ¾ of its capacity. Then, slowly introduce the stone into the glass, checking if it sinks or not.

If it sinks, you have before your eyes a real diamond; In the event that it floats to the surface or remains in the middle of the glass, you must discard its purity, since it is a false stone.

Why trust this test? Because real diamonds have a high density, so when the jewel is subjected to this homemade experiment, you can rest easy, since it is a reliable way for it to answer you how to know if a stone is a diamond.

Gloss test

If you have a piece of jewelery and want to check its authenticity, another of the infallible ways that will get you out of doubt about how to know if it is a diamond or a zircon is by verifying the brightness of the test, remembering what we had previously detailed.

Doing this test is very easy, since it is only a matter of placing the jewel before the light of a lamp and paying attention to the sparkles that the stone gives off. In the event that it is a real diamond, these flashes will present a grayish tone, characteristic of these precious jewels.

It must be noted that, when doing this test, you should not confuse flashes with reflections, since, in the case of the former, it is caused by the brightness or intensity of the light, while the reflection occurs because of the color of the light that is refracted in the stone. In addition, there is moissanite, a stone even brighter than diamond, which has made many jewelers indistinguishable from one another.

To differentiate both jewels, you must use a pocket torch and illuminate the interior of the stone. In it you must rule out if a double refraction occurs, notable when seeing the colors of the rainbow, since, if this phenomenon occurs, you can have a moissanite on hand.

Steam test

You often ask yourself how do I know if I have a real diamond? You may be surprised with this easy but reliable way to check it. Take the jewel to be valued and exhale on it, then detail whether or not steam or mist appears on the stone. If there is no steam, congratulations! You have a real diamond. In the opposite case, that is to say, that a stain appears on the surface of the jewel, it is most likely that it is a forgery.

Point test

Another easy test to rule out fake diamonds is the dot test. Doing it is simple: with the help of a pen, draw a small dot on white paper; Next, place the jewel to be evaluated on the center of this point. 

Now look carefully through the stone to see if there is a circular reflection in it. If so, it is a fake, if this phenomenon does not occur or the point cannot be seen, then it is a real diamond. This test is used to verify the transparency of the stone that, as we remember, in the diamond does not appear As crystal clear as you think.

Heat test

According to the characteristics of a diamond that we mentioned above, resistance is another of the aspects that can be evaluated through a home or professional test. How to do it? Heat the stone with a lighter for 30 seconds, immediately submerge the jewel in cold water and check if it breaks or cracks. If this happens, bad news! It’s a fake diamond.

Why is it an effective test? The reason is that it is one of the best ways to verify the hardness and resistance of diamond, one of the hardest minerals in the world.

Diamond appraisal by a professional

If you still have doubts or think that you are looking at a real diamond and you want it to be appraised to find out, for example, how much a small diamond is worth, then put the stone in the hands of a specialized jeweler who has the ideal equipment for appraise this gem.

This jeweler can make a complete appraisal, which includes the weight of the piece by means of a highly sensitive scale and determine the carat level it possesses; an examination by means of a magnifying glass or microscope to verify transparency, brightness and color; heat test through an electroconductivity meter to be sure of the hardness and resistance of the diamond and inspection of the stone under ultraviolet light to check for strong or intermediate blue fluorescence which determines the authenticity of the gemstone.

It should not be forgotten that, to specify the appraisal, the stone is subjected to a final test that allows us to see the radiolucent molecular structure typical of diamonds. In the case of fake diamonds, they become radiopaque to these rays.

Knowing how to identify a diamond is essential if you receive or want to give a precious jewel of this type or, in other cases, you have had a stone for a long time and want to know what it is. If, through the home tests that we have precisely described, you still do not clear up your doubts related to the veracity of the jewel, then we advise you to go to a professional since he has an accurate and trained eye that will check how to know if a diamond is real. If the precious stone is authenticated, all that remains is to treasure it and keep it safe.
