Certification tanzanite consists of 8 stages:
- Conclusion of a contract for the provision of certification services between the gemological laboratory and the client on the basis of registration documents for legal entities or a passport for individuals;
- Provision of tanzanite for examination (if there is data on tanzanite, they can also be provided for their confirmation or refutation during the examination);
- Confirmation of the conformity of the material of the stone submitted for examination to a natural diamond, as well as determination of the nature of its origin and possible refinement;
- Weighing, measuring linear dimensions, determining luminescence parameters, setting quality characteristics (color and purity), obtained as a result of the examination by a panel of gemological experts;
- Determination of cutting characteristics (proportions, symmetry and polishing), both visually and using an electron beam proportionoscope;
- Agreeing the results of the preliminary examination with the client;
- Photographing tanzanite (if necessary);
- Entering the certificate of conformity into the electronic database of the gemological laboratory.
The time required for certification of tanzanite depends on the complexity of the certified object - the more unusual the diamond in its physical and chemical properties, the longer the certification procedure may take.
What is the difference between an expert opinion and a certificate of conformity
The mandatory attributes of the certificate of conformity, including tanzanite, are the signature of the gemologist who conducted the examination and the seal of the organization that issued the certificate.
The certificate also establishes the fact of compliance with the requirements of the standards on the basis of which the certification is carried out. This is how a certificate of conformity differs from a gemological expert opinion, which is a final document reflecting the results of the collegial work of gemological experts.
