TATHATĀ Jadeite Receives NGTC Certification: Authority Meets Authenticity
We're proud to share that our jadeite pieces have received official certification from the National Gemstone Testing Center (NGTC)—China's premier authority in jadeite authentication.
This independent verification confirms what we've always known: our Burmese jadeite meets the highest standards of natural, untreated Grade-A quality.
NGTC: The Gold Standard in Jadeite Authentication
The National Gemstone Testing Center (珠宝玉石首饰检测中心) isn't just another testing laboratory. Operating under China's Ministry of Natural Resources, NGTC represents the definitive authority in jadeite verification, trusted by collectors, museums, and luxury houses worldwide.
Their gemologists examine hundreds of thousands of jadeite pieces annually, using advanced spectroscopic analysis to detect treatments invisible to the human eye. When NGTC issues certification, it carries weight across the global gem trade.
For anyone investing in jadeite, NGTC certification is the benchmark.
What NGTC Certification Confirms
Each NGTC certificate provides comprehensive verification:
- 100% natural jadeite composition—not nephrite, serpentine, or other jade simulants
- Grade-A status—completely untreated, with no chemical processing, polymer filling, or artificial coloring
- Precise gemological specifications—verified measurements, weight, and physical properties
- Registered authentication—every certificate number is independently verifiable in NGTC's database
The distinctive red seal you see on our certificate isn't just ceremonial. It represents rigorous scientific testing and the institutional authority of China's foremost gemological experts.
Why This Matters
The jadeite market faces ongoing challenges with treated stones and misrepresentation. Grade-B jadeite (bleached and polymer-impregnated) and Grade-C jadeite (artificially dyed) can superficially resemble natural pieces, but lack both the integrity and lasting value of authentic Grade-A material.
NGTC certification cuts through market ambiguity with objective scientific analysis.
When our jadeite passes NGTC testing, it validates not just the stone itself, but our entire sourcing philosophy—direct relationships with Myanmar mines, careful selection, and unwavering commitment to authenticity.
Heritage Meets Scientific Verification
For so many years, we have worked directly with Burmese jadeite at the source. We've built our reputation on knowing how to recognize genuine quality, understanding the geology of Myanmar's jadeite-forming regions, and maintaining relationships with miners who share our standards.
But heritage and expertise, while valuable, benefit from independent verification.
NGTC certification provides that external validation—objective proof that our claims stand up to the industry's most rigorous testing.
It's one thing for us to say our jadeite is natural Grade-A. It's another when China's highest gemological authority confirms it.
What This Means for Our Customers
Every piece that comes from TATHATĀ carries the same commitment to authenticity, whether individually certified or not. Our sourcing doesn't change. Our selection standards don't change. Our integrity doesn't change.
NGTC certification simply makes that integrity visible and verifiable.
For collectors, investors, and anyone making a significant jadeite purchase, this independent verification offers an additional layer of confidence. You're not just trusting our word—you're backed by scientific analysis from the institution the entire industry respects.
Beyond the Certificate: Our Ongoing Commitment
Receiving NGTC certification isn't a one-time achievement. It's a reflection of consistent standards we maintain across our entire collection.
From everyday talismans to museum-quality collector pieces, from our bangle collection to custom commissions, the same principle applies: authentic Burmese jadeite, naturally formed, untreated, and honestly represented.
NGTC certification proves we can meet that standard when put to the test.
