Major Trading
Precision gemstones for watchmakers and fine jewellers worldwide
Precision. Provenance. Partnership.
Three generations of calibrated coloured gemstones for the world's most demanding watch and jewellery houses. From Geneva, Paris, and London.
What we do
How we work
Three ways we work with watch and jewellery houses, depending on what you need: precision-calibrated stones for watch dials, matched parcels for haute joaillerie collections, or curated singles, pairs, and sets ready to buy.
Precision measured in hundredths of a millimetre
Calibrated coloured stones to ±0.02mm tolerance for tier-1 manufacturers worldwide. From cabochons to custom tapers, we deliver the certainty your production schedule requires.
Matched sets for luxury collections
Bespoke matched parcels for haute joaillerie, sourced and matched to your brief. Complete colour uniformity, ESG documentation, three generations of partnership.
Singles, pairs, and sets, ready to buy
Individually selected coloured gemstones for trade. Each stone professionally photographed, certified, and documented under our Five-Level Traceability Standard.
Provenance documented
Fully traceable supply
Traceability is about following the stone's journey from the point it was unearthed. Our Five-Level Standard documents provenance from mine to manufacture, supporting ESG compliance and enabling your brand storytelling.
We've been doing this for three generations. We just finally wrote it down.

Three generations, three offices
Major Trading is a family business specialising in coloured gemstones for the world's most demanding watch and jewellery houses. Founded in 1987, we work from offices in London, Geneva, and Paris.
Our work is precision, provenance, and partnership. The work itself is what makes the difference: how we calibrate, how we source, how we document.
