Certification of precious and other gemstones is a crucial aspect of gemology and appraisal services, catering to both corporate entities and individuals.
Why Certification Matters? A certification for a gemstone verifies its compliance with the standards applied by the laboratory during its gemological assessment.
What Information Does the Certification Provide for Cut Gemstones?

Detailed commentary from the expert laboratory regarding enhancements, if any, including type and degree of treatment.
Comprehensive identification of the gemstone, specifying its natural origin, weight, dimensions, fluorescence, and qualitative attributes such as color, clarity, and cut quality, in accordance with certification standards.
Choosing the Right Certification Type Maintaining neutrality between producers, sellers, and buyers, our company ensures objectivity and independence in gemological evaluations. Essential attributes of the certification include the signature of the chief gemologist and the organization's seal. Additionally, it confirms the gemstone's adherence to certification standards, distinguishing it from a gemological expert opinion, which reflects the collaborative effort of gemologists but may not align with our evaluation system.
Who Needs Certification?
Both sellers and buyers benefit from possessing a certification for a gemstone.
For sellers, acquiring a certification enhances the marketability of their product, while buyers gain personalized insights into their purchase.
Types of Certifications The gemstone certification process involves several stages:
Contract agreement for certification services between the gemological laboratory and the client, based on registration documents for corporations or personal identification for individuals.
Submission of the gemstone for examination (existing data on the gemstone can also be provided for validation or refutation during the examination).
Determination of the material of the gemstone, its correspondence to the mineral type, variety, mineral substance (mineraloid or natural gem formation), as well as identification of its origin and potential enhancements.
Weighing, measuring linear dimensions, determining fluorescence parameters, and assessing qualitative characteristics (color, clarity, and cut quality) by a team of expert gemologists.
Reviewing preliminary examination results with the client.
Photographing the gemstone.
Recording the certification in the electronic database of the gemological laboratory.
The duration of gemstone certification depends on the complexity of the object. The more unusual the gemstone in terms of its physical and chemical properties, the longer the certification process may take.
