Karat-Boutique is a luxury gemstone and jewelry brand dedicated to timeless elegance, premium craftsmanship, and carefully selected precious stones.
Founded by a third-generation gemologist, Karat-Boutique was born from a quiet rebellion against mass-produced luxury. We chose to remain small, to remain attentive, to remain devoted to the stones themselves.
Today, the maison serves a discrete clientele across five continents — collectors, families, and patrons who understand that true luxury is patience.
To preserve the art of slow, considered jewelry making in an era that has forgotten how to wait.
To be the maison clients return to across generations — for a wedding band, a milestone, an heirloom passed down.
Every stone, every setting, every signature traceable, ethical, and signed by the hands that made it.
A single signature ring at Karat-Boutique can take 120 to 400 hours of bench work. Our jewelers train for fifteen years before they are entrusted with a primary stone.
We polish by hand. We set by hand. We sign each piece by hand. Nothing leaves the atelier without passing through the eyes of three master craftsmen.

Our clients trust us with extraordinary pieces — that trust is sacred.
Honest provenance, transparent grading, no shortcuts — ever.
We refuse far more pieces than we make. The bar stays high.
We design for fifty years from now, not next season.
A single bench in a back room off Place Vendôme. Three stones, one apprentice, one promise.
Our first private salon opens, by appointment only, on Rue du Rhône.
The Karat signature setting is patented — a setting designed to disappear into the stone.
The maison adopts the strictest mine-to-setting traceability standard in the industry.
Paris, Geneva, Dubai, Tokyo, New York — each unmistakably Karat.
