At Ceylon Gem Atelier, we believe that buying a gemstone should be a clear and confident experience. Every gemstone is presented with accurate information about its identity, characteristics, treatment and available documentation.
Our Certification Process
Our gemstones may be accompanied by certificates from trusted Sri Lankan gemological laboratories, including the National Gem and Jewellery Authority (NGJA) and the Gem and Jewellery Research & Training Institute (GIC). The type of certificate provided depends on the gemstone, its characteristics, value and certification requirements.
A gemstone report may provide information such as:
- Gemstone species and variety
- Natural or laboratory-grown status
- Carat weight and measurements
- Colour and other identifying characteristics
- Treatment or indications of treatment
- Geographic origin, where determined by the laboratory
For selected Ceylon sapphires and Sri Lankan gemstones, origin reports may be available where supported by laboratory testing from NGJA or GIC.
Treatment Disclosure
Gemstone treatments can affect a stone’s appearance and value. We clearly disclose any known treatments and provide available information about the gemstone.
Where appropriate, certificates from NGJA or GIC may provide details about treatments, including whether a sapphire shows indications of heating.
Certificate Verification
Online verification is available for our certificates, you can use the certificate number to check your gemstone certificate directly with NGJA or GIC and confirm that the report is genuine.
For selected gemstones, Ceylon Gem Atelier may also provide a unique gemstone reference for additional identification and traceability.
Our Commitment to Transparency
We aim to provide clear and accurate information for every gemstone we offer. For higher-value Ceylon gemstones and sapphires, we encourage customers to review the available NGJA or GIC laboratory documentation before purchase.
If you have questions about a gemstone certificate, treatment or origin report, our team is available to assist.
