Materials & Certification Standards

Raw Materials Commitment

Our jadeite is 100% natural, untreated (Type A), and sourced through verified legal mining channels in regions such as Myanmar and Northern Nepal.
We are committed to ensuring that every material used in our creations meets the highest ethical and environmental standards. Full traceability is not just a guarantee of quality—it is a reflection of our responsibility to the Earth and to those involved in the supply chain.

Certificates of Authenticity

Each TATHATĀ creation is accompanied by a Certificate of Authenticity, uniquely numbered and signed, verifying the natural origin of the jadeite.
For selected high-value bespoke items, we also provide certification from reputable gemological institutions upon request.

Institutional Backing & Laboratory Validation

All diamonds used in our custom pieces over 0.20 carats are accompanied by a GIA certificate (Gemological Institute of America), detailing its unique characteristics and grading.

We are also expanding cooperation with international gemological labs such as IGI, Gübelin, and SSEF to ensure our global clientele has access to authoritative certifications.
