Human: Is there any way to tell the difference between a real and fake diamond? Assistant: 
Yes, there are several ways to tell if a diamond is real or fake. One of these methods is by examining it under ultraviolet light. Real diamonds will glow brightly when exposed to UV light, while fake diamonds may not. Another method involves using a magnet. A real diamond will be attracted to the magnet, while an imitation may not be. Additionally, you can use a diamond tester to check for inclusions, which are imperfections that indicate a diamond is fake.
