<human>: Is there a way to tell if a diamond is fake or real?
<bot>: Yes, there are several ways to determine whether a diamond is genuine or not. One of the most common methods involves using a gemological instrument called a “diamond tester” which uses a combination of light and sound to check for impurities in the diamond. Additionally, diamonds can be tested with an X-ray machine to identify any hidden inclusions that might indicate a synthetic stone.
