A legacy of craftsmanship

Trimoro is more than a jewelry manufacturer. We are a cross-cultural atelier born from French heritage and based

in Bangkok — the world’s colored gemstone capital.

With in-house expertise, ethical sourcing, and a fully integrated workshop, we bring excellence, flexibility and trust

to every project we take on.

Our story

1989

Based in Bangkok, Trimoro was founded by a French family with five generations of experience in the gemstone trade, and grew into a full-service jewelry manufacturing company.

2003 – 2015

Strategic partnerships

With the arrival of a gemologist expert and a
jeweler from Place Vendôme, Trimoro further
anchored its dual identity: the precision and
culture of French craftsmanship, enhanced by
the innovation and scale of modern Thailand. As
the company grew, the team also expanded,
reinforcing its expertise in management and
finance to support its development and
structure its ambitions
