The Story
Founded in the heart of New York City, Trillion Carat began as a small atelier dedicated to one idea: that extraordinary jewelry should be within reach — without compromising on ethics, quality, or beauty.
Over two decades and more than ten thousand handcrafted pieces later, that idea has grown into a global community of clients who trust us for the most important moments of their lives — proposals, weddings, anniversaries, and milestones both grand and quiet.
We work exclusively with GIA-certified natural diamonds and premium lab-grown stones — because we believe knowing exactly what you own is not a luxury, it is a right. Every ring, necklace, and band that leaves our workshop is accompanied by a certificate of authenticity and our lifetime structural guarantee.
Our Values
What We Stand For
Ethical Sourcing
Every gem we work with is either lab-grown or conflict-free certified. We believe luxury should never come at a human or environmental cost.
Bespoke Craftsmanship
Each piece begins as a conversation. Our master jewelers work with you to create rings, necklaces, and bands that are entirely your own.
Lifetime Guarantee
We stand behind every piece we create. All Trillion Carat jewelry comes with a lifetime structural warranty and complimentary annual inspections.
GIA-Certified Diamonds
Transparency is non-negotiable. Every diamond we sell is GIA-certified and accompanied by its grading report so you know exactly what you are purchasing.
