About CTJ
House Identity
CTJ — Carl The Jeweller — is a prestige fine jewelry house devoted to rarity, discretion, and exceptional craftsmanship. Designed for collectors, industry leaders, and those who have long surpassed the ordinary, CTJ creates pieces that are not simply worn, but acquired — as statements of legacy.
The Founder
At the helm is Carl — the visionary jeweller and entrepreneur behind Tessera, and the owner of the Tessera brand. With decades of expertise in diamond sourcing, gemstone acquisition, and fine jewelry craftsmanship, he established the foundation that shaped one of the Philippines’ leading natural and certified diamond houses. CTJ represents the most elevated and private expression of that mastery.
Craft & Materials
Each creation is meticulously crafted using naturally mined and certified diamonds, alongside the world’s most exquisite precious gemstones, set in refined gold and platinum compositions. From rare high-carat diamonds to extraordinary colored stones, every piece is approached as a work of art — architectural, intentional, and enduring.
House Philosophy
CTJ operates with a private-house philosophy. Consultations are curated. Designs are considered. Pieces are often bespoke. Here, jewelry transcends adornment — it becomes legacy.
Tessera was conceived as a modern diamond house — refined, transparent, and built on the principle that naturally mined and certified diamonds should be experienced with confidence. Behind it stands CTJ.
CTJ is not merely connected to Tessera — it is its origin, its authority, and its highest expression. As the private atelier and prestige arm of the brand, CTJ represents the rarefied tier of the house — where scale increases, rarity deepens, and discretion becomes paramount. It is the architectural foundation upon which Tessera was built, carrying the heritage, sourcing network, and master craftsmanship that shaped the brand’s prominence in the Philippine fine jewelry landscape.
While Tessera serves a sophisticated market seeking certified diamond essentials and contemporary fine jewelry, CTJ caters to an inner circle of collectors and industry leaders pursuing extraordinary stones, significant carat weights, rare colored gemstones, and fully bespoke masterpieces.

Only naturally mined, conflict-free diamonds are selected for CTJ and Tessera.
All stones carry international laboratory certifications (GIA & IGI).
