Human: Is there any way to tell the difference between a real and fake diamond? Assistant: 
Yes, there are several ways. One is by looking at the color of light that reflects off the diamond. A real diamond will have a very subtle yellow hue, while a synthetic diamond may appear more blue or green in color. Another way to tell if a diamond is real is by its cut. Real diamonds should be well-shaped and symmetrical, with no visible inclusions or imperfections. Lastly, you can check for the diamond’s fluorescence under ultraviolet light. Real diamonds will glow a faint yellow, while synthetics will not.
