How We Certify Our Gemstones
Gemstone Authenticity Verification Process at Rasikh Gems & Jewellers
All natural gemstones at Rasikh Gems & Jewellers undergo thorough authentication and verification prior to display, ensuring only genuine stones reach our showroom.
Each stone is examined for natural origin, checked for common treatments and enhancements, and graded against internationally recognized standards before being sent for independent lab certification through GIA, GRS, IGI, and seven other recognized laboratories.
What's Included in a Gemstone Certification Report
A gemstone certification report from GIA, GRS, IGI, or one of our seven other partner labs typically confirms the stone's natural origin, identifies any treatments (such as heat treatment or oiling), and documents its weight, dimensions, and key quality characteristics. This documentation is what separates a certified natural gemstone from an unverified one and is the basis for its fair market value.
How to Verify Your Gemstone Certificate (GRS Certificate Verification and Other Certificates Too)
Do you want to ensure that your gemstone certificate is authentic? It is easy for you to do so by verifying your certificate through the report checking facility provided by the issuing laboratory. This can be done via a GRS report check, GIA report verification, or even a certificate issued by one of the other laboratories we work with.
