To tell if a pearl is natural or cultured, check for uniformity and surface flaws. Natural pearls tend to be less uniform in shape and have more imperfections. You can also use X-ray testing, which reveals the pearl's internal structure. Cultured pearls often have a more perfectly round nucleus inside, whereas natural pearls are solid with rarely a discernible core.
