<human>: Is there any way to tell if a diamond is real or not?
<bot>: Yes, there are several ways to determine whether a diamond is real or fake. One way is to look at its clarity grade. A diamond that has a clarity grade of VS2 or higher is considered real and should have few visible inclusions. Additionally, you can use an X-ray fluorescence (XRF) machine to test the diamond for elements such as nitrogen and cobalt, which are often used in synthetic diamonds.
