Many high-end jewelry wearers turn to professionals to find out if the diamonds they hold are genuine. However, you can answer this question yourself. To do this, you need to carry out a number of fairly simple experiments.
Fogging stone
One of the simplest ways to authenticate a diamond is to determine its response to moisture. Bring the diamond to your mouth and slowly exhale into it. If you notice the stone fogging up for a few seconds, the diamond is most likely fake. A genuine diamond has the ability to instantly dissipate heat, so haze is almost invisible on it. If you see this kind of haze, it disappears much faster than on fake diamonds. In addition, if you repeat this experiment several times, the result will always be the same on a real diamond. With each new approach, a fake stone will be covered with moisture more and more, condensation will form on it.
Metal
If you are authenticating a diamond on a piece of jewelry, pay attention to the metal it is placed in. Earrings, rings, and other real diamond jewelry are likely to be made from real gold, silver, or some other precious metal. Equip yourself with a magnifying glass and check the product for a sample mark. If there is one, the probability that the diamond is genuine is very high. At the same time, you may find the inscription CZ (Cubic Zirconia), which means that the diamond is of synthetic origin.
Natural defects
Real diamonds are usually rarely perfect in composition. Take a close look at it with a magnifying glass. If you see blotches of foreign minerals or slight discoloration, the chances are very high that this is a real diamond. Synthetic diamonds are grown under laboratory conditions; they do not have such defects, because are produced in sterile purity. However, the absence or presence of such defects cannot be a determining factor. Even real diamonds can be perfectly clean. Be sure to do more research.
Refraction
If you have a fairly large stone, you can determine its authenticity by checking its refraction. Take a newspaper and look at it through a diamond. If you can read the printed text, or at least see it with a lot of distortion, rest assured that it is a fake diamond. A genuine diamond refracts light very strongly, so it is almost impossible to see anything specific behind it, unless it is specially prepared.
Heating
A real diamond is a very hard material and can be difficult to break. Heat the stone with a small fire for 30 to 40 seconds, then quickly dip it into a glass of cold water. If the stone is made of glass or quartz, it will quickly crack.
