Putting your diamond through wet testing Fill a glass halfway with water and put your diamond into it. Due to the great density of the stone, a genuine diamond will sink to the bottom of the glass. If it's a forgery, it will float on the water's surface. This method is also called "diamond dipping."
Testing a diamond by hand Use the micrometer measurement tool to check the weight of your stone. If it is under 55 carats (100 grams), it's underweight. If it weighs more than that, it's oversize. These are signs that it may be a fake.
Locating any defects When viewing a diamond in a store window or online, look for any abnormalities. Some problems may not be visible from a distance, but they can be detected up close with a microscope. For example, there might be some areas on the stone where the color is not consistent. These spots are called "inclusions" and they usually occur due to impurities within the carbon structure of the stone. Other defects include cracks, bubbles, and twists. A reputable dealer will tell you if they find any issues during the process. They'll also provide information on how much those problems affect the value of the stone.
Doing research Before you buy a diamond, know what types of stones are worth the most money. There are three main categories: colorless, brown, and red.
How to Tell whether a Diamond Is Real or Fake
To see whether your diamond is genuine, hold it up to your lips and, like a mirror, fog it up with your breath. If the stone remains fogged for a few seconds, it is most likely a forgery. Because condensation does not adhere to the surface of a genuine diamond, it does not fog up quickly.
Fogged diamonds are easy to recognize because they will remain transparent even under bright light conditions. Also, polished forgeries tend to look more reflective than genuine stones. Finally, be sure to check the cut of the stone; although modern cuts may appear similar, some are better suited for certain types of jewelry than others. For example, if you were to wear a large, rough-looking stone, it would be obvious that you weren't wearing a ring.
The best way to ensure that you aren't buying a forgery is to contact one of the many certification agencies out there. They will be able to help you determine whether or not your diamond is legitimate. The three main certification agencies are the Gemological Institute of America (GIA), the Diamond Council of Canada (DAC), and the Israeli Diamond Authority (IDA). Each agency has its own requirements for what it considers to be a genuine diamond, so make sure to read all of the information provided before you decide which company to use.
Finally, be careful not to purchase diamonds from online dealers as these often include copies or replicas instead of real diamonds.
Place the stone on the dot, flat side down. Look down onto the paper through the pointed end of the diamond. It is a fake if there is a circular reflection inside the gemstone. If there is no dot or reflection in the stone, the diamond is genuine.
To put a diamond to the test in a new way, set it under a UV light and see the reaction. Most diamonds, but not all, will generate a blue-colored light. Some diamonds do not shine when exposed to UV light. As a result, if the stone does not light, the results do not always show that it is a fake diamond.
Also, remember that just because something has a high price tag doesn't mean it's worth what they are asking for it. There are also counterfeit diamonds out there that look exactly like the real thing. Don't be fooled by their quality. They aren't worth more than what you pay for them.
Finally, don't forget to wear protective gear when working with gems and jewelry. Use protection against chemicals (mask if necessary), sharp objects, and electric shocks.
These are just some of the many ways to identify real from fake precious stones. There are other tests too that can help determine whether or not you should buy a particular piece of jewelry. If you have any doubts about the authenticity of a gem, then don't waste your time or money! Just walk away from it. Someone who wants to harm you will find a way. So, stay safe and keep an eye out for suspicious people or items.
