The Gem Trade


And traceability

Piat is one of the last French Maison with an expertise of rough gems. The workshop in Bangkok allows the company to keep up to date with mines opening or closures, new stones availability as well as markets trends and supply.

With his expertise and extensive market knowledge over three generations, Piat provides exceptional natural gems to his customers and meets all specific requests.

Emmanuel Piat also purchases rough stones directly from the production sites to meet demands for a particular shape and minimize weight loss during the adjustment work. Buying rough gems guarantees him the traceability and helps him control the presence of treatment in the gemstones.
