Certification & Transparency
At Siam Gems Club, transparency and trust are at the heart of everything we do. Each gem that finds its way into our collection has passed through many hands — miners, cutters, and traders we know personally and have worked with for years. We believe that true confidence comes from knowing where your gemstone comes from, and how its quality is verified.
That’s why we regularly send selected stones from every new parcel or batch we acquire for laboratory verification. This allows us to confirm the authenticity, treatment status, and overall quality of our gemstones before they appear in our shop.
Included Certification
All gemstones with a value of 499 USD or above include a professional certificate by default.
Our standard included report is the Standard Identification Report with Photo, issued by GLC – Chanthaburi Gemological Laboratory. This report confirms the gemstone’s identity and key characteristics and includes a reference photograph.
Some products already display “Certificate Included” on their pages. Others may currently be undergoing certification or can be certified upon request before shipping.
Certification on Demand
For gemstones below 499 USD, you can easily add certification for an additional fee. Several types of certification are available depending on the level of analysis required.
Our standard certification is carried out through GLC - Chanthaburi Gemological Laboratory, a well-known laboratory located in Thailand`s historic gemstone trading center of Chanthaburi.
Upon request, we can also arrange certification with other respected Thai gemological institutes such as GIT – Gem & Jewelry Institute of Thailand or GGT - Gemological Laboratory, Bangkok, or GIA - Gemological Institute of America
⏳ Processing time: typically around 5-7 business days. If you prefer faster shipping and do not wish to wait for certification, please contact us at info@siamgemsclub.com or use our Contact Form.
