The First. The Only. Tessera Introduces IGI Co-Branded Jewelry Certification in the Philippines
The First. The Only.
Tessera is the only jewelry brand in the Philippines with co-branded certification from the International Gemological Institute (IGI)—verifying not just the diamond, but the entire piece.
At Tessera, we have always believed that fine jewelry should come with more than beauty—it should come with certainty. This belief has led us to redefine how trust is built in the industry.
A New Standard in Diamond Jewelry Certification
Traditional diamond certification focuses on loose stones. While this provides insight into a diamond’s quality, it does not fully represent the finished piece a client ultimately wears.
Tessera changes that.
A New Standard in Diamond Jewelry Certification
Through our exclusive partnership with IGI, we introduce co-branded jewelry certification in the Philippines, where the entire jewelry piece—diamond, setting, and craftsmanship—is verified and documented. This creates a more complete and meaningful standard for certification, aligned with how fine jewelry is truly experienced.
Why IGI Co-Branded Certification Matters
Every Tessera piece with an IGI co-branded certificate ensures:
Accurate grading of the diamond’s cut, color, clarity, and carat weight
Confirmation that the diamond is naturally mined and certified
Authentication of the finished jewelry piece, not just the stone
Credibility backed by a globally recognized gemological authority
For clients, this means full transparency—from the origin of the diamond to the final design in your hands.
Elevating Trust in Fine Jewelry in the Philippines
As a leading diamond jewelry brand in the Philippines, Tessera continues to invest in systems that empower clients with knowledge and confidence.
In addition to IGI certification, our boutiques are equipped with diamond verification tools, allowing clients to validate their diamonds in real time. This reinforces our commitment to authenticity, education, and long-term value.
Redefining the Jewelry Experience
With IGI co-branded jewelry certification, Tessera sets a new benchmark for diamond jewelry in the Philippines—one that goes beyond industry norms.
We are not simply offering certified diamonds.
We are offering fully verified jewelry pieces, backed by global standards and built on trust.
This is the future of fine jewelry. And it starts here.
