Gemstone Authentication

Gemstone Verification

What is Gemstone Authentication?

Gemstone authentication is the professional process of verifying whether a gemstone is natural, treated, synthetic, or imitation. This includes checking its physical, optical, and structural characteristics using expert techniques.

Our goal is to provide clarity, transparency, and peace of mind with every purchase.

FAQs

Certificate vs Guarantee Card

What is a Gemstone Certificate?
A gemstone certificate is a detailed report issued by a recognized gemological institute (such as GGI, associated with GIA). It verifies whether a gemstone is natural, treated, or synthetic based on professional testing standards.
What is a GK Jewelers Guarantee Card?
The GK Jewelers Guarantee Card is an official authenticity assurance issued directly by us. It confirms that the gemstone is genuine and backed by lifetime authenticity guarantee from GK Jewelers.
Is a certificate mandatory for every gemstone?
No. Certification is usually required for high-value or premium gemstones. Many natural gemstones do not require third-party certification and are safely sold with our Guarantee Card.
Which is more important – Certificate or Guarantee Card?
Both serve different purposes. A certificate provides laboratory verification, while the Guarantee Card offers brand-backed lifetime assurance. At GK Jewelers, customers receive one or both depending on the gemstone.
What if my gemstone does not have a certificate?
Even without a certificate, your gemstone is fully covered by GK Jewelers’ lifetime authenticity guarantee. You can always return for re-verification or guidance.
Can I request certification separately?
Yes. Customers can request third-party certification through GGI (GIA-associated) for eligible gemstones at an additional cost.
