Pearls are authenticated by examining factors like luster, surface texture, shape, and size. Professionals use tools such as X-rays to check for internal structures typical of natural pearls. They may also conduct a magnification inspection to spot imperfections and a tooth test to feel the slightly gritty texture. Certified gemologists can provide an official appraisal or certificate authenticating the pearl’s origin and quality.
