Analysis & grading Pearl Reports & Services Details

Pearl Reports

GIA Pearl Reports provide information on the identity of pearls (natural or cultured), the mollusc (when determinable) they originated from, the environment they formed within (saltwater or freshwater), and state whether the pearls have undergone any detectable treatments.  Multiple security features on GIA pearl reports ensure their authenticity. The reports include a digital image of the pearl(s).
