The Nantes WORKSHOP cuts and re-cuts colored precious stones!
Lapidary - Gem Cutter
Welcome to the Atelier des Gemmes Nantes website of the REDGEMS company for jewelry professionals and lovers of quality gems.

The REDGEMS company created in 2021 opened its boutique-workshop in NANTES in 2024 "L' ATELIER des GEMMES".
The workshop is managed with passion by our expert GEMMOLOGIST FEEG - ING 1391 (Federation of European Education in Gemmology)
It provides a guarantee of quality through its professional integrity, its best practices and its knowledge of colored gems.
We assess the quality of colored gems and determine their nature (many artificial ones unfortunately circulate on the market). Please note that we will not give market values which always remain complex to understand due to changes in demand.
As Lapidary, we cut rough gems to magnify them.
Size is one of the 4 criteria that increase the value of Gems. The other 3 are weight (carat), color and purity.
To achieve this goal, we work to be at the forefront of cutting. To do this, the workshop relies on classic and innovative (even atypical) designs (cutting drawings) according to the possibilities of light refraction for each type of gem.
We use high-precision lapidary equipment which allows for very high-quality cuts to best enhance this criterion.
We also re-cut old, worn, broken or damaged gemstones.
L’ATELIER des GEMMES guarantees you in this process a professional response on the characteristics of the gems and quality work.
