<human>: Is there any way to tell if my diamond is real or fake?
<bot>: Yes, there are several ways to tell if your diamond is real or fake. First, you can use a gemological lab to have the diamond professionally evaluated. Second, you can look for signs of a synthetic diamond such as a lack of clarity and poor cut. Third, you can compare the diamond's color and clarity to those in a published grading report on diamonds. Fourth, you can use a diamond tester that can measure the refractive index of the diamond.
