Is there any way to tell if a diamond is real?

Yes, you can tell if a diamond is real by looking for the four C's. The four C's are color, clarity, cut and carat weight. Color should be a deep yellow or white with no visible impurities. Clarity refers to the number of imperfections in the stone such as inclusions or blemishes. Cut refers to how well the diamond is cut and polished. Carat weight is the measure of a diamond's size. If all four C's are present then it is likely that the diamond is real.
