Frequently Asked Questions

How do I know the mollusk type or whether my pearls are cultured or treated? Does GIA check this?


Pearls may have old reports or sales documentation specifying identification information. If you’re uncertain, it is best to request a GIA Pearl Identification Report or GIA Pearl Identification and Classification Report. If during visual examination gemologists suspect a treatment or mollusk type misidentified, then the pearls will be switched to a more appropriate pearl service.
