What a Tanzanite Certificate Confirms—and What It Does Not

A gemological certificate is a technical document, not a valuation.

It verifies gemstone identity, confirms natural formation, and documents origin where applicable. In the case of raw tanzanite, certification focuses on species identification and authenticity rather than polish or cut.

Because each Merelani Untamed crystal remains untreated and unaltered, the certificate serves as a permanent record of geological truth—linking the stone directly to its origin.

This documentation becomes part of the stone’s long-term provenance.
