How can I tell if a diamond is natural or synthetic?
assistant
Natural diamonds are formed deep within the Earth and have no man-made elements. Synthetic diamonds, on the other hand, are created in a lab and contain man-made impurities. To determine whether a diamond is natural or synthetic, look for visible inclusions such as graphite or boron in the stone. If these are present, it's likely that the diamond is synthetic. Additionally, examine the color of the diamond to see if it has an unnatural hue.
