How to know if diamonds are real?

Answered by Jason Smith

There are several ways to determine if a diamond is real or fake, and one of the methods is by testing its density using water. This method is simple and can be done at home with just a regular glass and some water.

To start, fill a glass about ¾ of the way full with water. Make sure the glass is clean and free from any substances that could affect the test.

Next, gently drop the diamond into the glass of water. It’s important to handle the diamond carefully to avoid any damage.

Now, observe what happens to the diamond in the water. If the diamond sinks to the bottom of the glass, it is most likely a real diamond. This is because diamonds have a high density, which causes them to sink in water.

On the other hand, if the diamond floats at the surface or just underneath, it is likely a fake diamond. This is because most fake diamonds, such as cubic zirconia or glass, have a lower density than real diamonds, causing them to float or barely sink in water.

It’s worth noting that this method is not foolproof and may not always provide accurate results. Some fake diamonds can be made to have a similar density to real diamonds, making them sink in water. Additionally, other factors, such as the shape and size of the diamond, can also affect its buoyancy in water. Therefore, it’s always recommended to consult with a professional jeweler or gemologist for a definitive assessment of a diamond’s authenticity.

In addition to the water test, there are other methods you can use to determine if a diamond is real. These include testing its hardness with a diamond tester or scratching it against a known diamond or a piece of glass. Real diamonds are the hardest substance on Earth and can only be scratched by another diamond.

You can also examine the diamond’s clarity, color, and cut. Real diamonds often have unique internal and external characteristics that can be seen under magnification. They also reflect light in a distinct way due to their precise cut.

Furthermore, certification from a reputable gemological laboratory, such as the Gemological Institute of America (GIA), can provide assurance of a diamond’s authenticity. These certifications provide detailed information about a diamond’s quality and origin, giving you confidence in its authenticity.

While the water test can be a quick and simple way to get an initial idea of a diamond’s authenticity, it is not a foolproof method. To ensure accurate results, it’s advisable to consult with a professional jeweler or gemologist and consider other tests and certifications to determine if a diamond is real or fake.
