Matched sets for high jewellery collections
Parisian haute joaillerie demands perfect uniformity across 50, 100, or 500 pieces.
We source, match, and document complete sets with the colour consistency and ESG compliance your maison requires.
The Challenge
Maintaining colour across the full collection
Creating a haute joaillerie collection means maintaining absolute colour consistency across dozens or hundreds of matched stones. When stones arrive from different suppliers or parcels, colour variation becomes visible in the finished pieces.
Today, luxury houses also face increasing pressure for ESG compliance and documented provenance. Your clients want to know the story behind their jewellery, but most suppliers can't provide complete documentation.
You need a partner who understands both the aesthetic demands of haute joaillerie and the compliance requirements of modern luxury brands.
Our Approach
Sourced for your project, matched to your standard
We work from our Paris office with procurement and design teams to understand your collection requirements. Whether you need 50 matched rubies or 500 sapphires, we source material specifically for your project.
Every set is colour-matched under controlled lighting before delivery. You receive sample approval at every stage. And unlike standard suppliers, we provide complete traceability documentation for every stone, from mine to your atelier.
We've been doing this for three generations. Different problems, different solutions, same outcome, satisfaction.

Every stone in the set visually matched under controlled lighting. Sample approval before final delivery.

Colour Matching
Colour matched to your standard
Matched parcels for haute joaillerie require colour consistency that lab values alone don't deliver. Major Trading matches against documented reference masters, including the central master covering blue sapphire, pink, ruby, emerald, tsavorite, spessartite, and aquamarine.
For each project, we create a project-specific master against which all stones are matched. Sample stones approved by your design team before production. Full set re-verified before delivery, against the agreed reference.
ESG and Traceability
ESG compliance built in
Luxury groups increasingly require documented provenance for all materials. Our Five-Level Traceability Standard provides the documentation your compliance team needs, from mine partnerships to dealer relationships.
Every stone in your set comes with complete documentation suitable for ESG reporting and client communication. Not just certificates, actual provenance records.
Major Trading is RJC-certified, supporting your compliance reporting at every level.
