Jewelry industry can identify this phenomenon by looking at photos, because photos are direct evidence to distinguish different jewels and jade, and the photos of identification certificates are clear and accurate, which will greatly increase the difficulty of forgery. However, in some cases, because the jewelry styles are similar and the photo features are similar, it is difficult to distinguish them. In this case, the accurate weight is another valid data that can be verified.

This phenomenon is reasonable, because photos can provide intuitive visual information to help professionals judge the quality, color, cutting and other characteristics of gems. However, it is also risky to identify gems only by photos, because photos may not fully show the real situation of gems, especially for some gems with similar appearance, it is difficult to make accurate judgments only by photos.

Therefore, in jewelry appraisal, in addition to photos, other detection methods, such as physical detection and instrument measurement, need to be combined to ensure the accuracy of appraisal results. At the same time, when consumers choose jewelry appraisal services, they should also choose qualified and reputable professional institutions to reduce risks.
