How to Determine if a Diamond is Real: Check Certification, Look for Inclusions, and Investigate Price


Buying a diamond can be a daunting task, as there are many factors to consider. One of the most important factors is determining if the diamond is real. This article will provide a comprehensive guide on how to determine if a diamond is real.

Check for a Certification Card

The first step in determining if a diamond is real is to check for a certification card. A certification card, also known as a grading report, is issued by a gemological laboratory and provides an assessment of the diamond’s characteristics such as cut, color, clarity, and carat weight. Additionally, the certificate will include the diamond’s unique serial number, which can be used to verify its authenticity.

Look for Inclusions

Inclusions are tiny natural imperfections that occur inside a diamond. These imperfections can be seen with the naked eye, although some may require a magnifying glass. Generally speaking, the fewer inclusions a diamond has, the higher its value. Therefore, it is important to inspect the diamond carefully for inclusions before making a purchase.

Use a Magnifying Glass

Using a magnifying glass can offer a more detailed view of the diamond and help to identify any inclusions. It is important to look for any flaws or blemishes that may indicate the diamond is not real. Additionally, a magnifying glass can be used to look for other features such as laser-drilling and feathers, which can also indicate the diamond is not real.

Perform a Fog Test

The fog test is another way to determine if a diamond is real. To perform the fog test, simply breathe on the diamond and observe how quickly the fog dissipates. If the fog dissipates quickly, the diamond is likely real. However, if the fog lingers, the diamond may not be real.

Investigate the Price

The price of a diamond can offer clues as to whether it is real or not. If the price seems too good to be true, it is likely the diamond is not real. It is important to remember that diamonds are expensive and should be priced accordingly.


Determining if a diamond is real is a complex process that requires careful inspection. By following the steps outlined in this article, including checking for a certification card, looking for inclusions, using a magnifying glass, performing a fog test, and investigating the price, you can be sure to make an informed decision when purchasing a diamond.
