Would you like to come and discover Auvergne amethyst for yourself?
We organize visits to the Mines de Poux site during the summer season!
Alone, with family or friends, come discover the vein and collect your own amethysts!
The Compagnie des Minéraux d'Auvergne (or COMINAUV) was created in March 2018 under the leadership of Nicolas LEGER and Mathieu MOULIN, with the aim of on the one hand relaunching extractive know-how and French lapidary art in through different minerals present in our territory, and on the other hand to contribute to the development and dissemination of scientific knowledge on minerals.
Its missions therefore encompass the prospecting, extraction, processing and marketing of mineral materials, as well as any scientific and cultural activity linked to minerals. It begins its activities in Auvergne, a region rich in mineral resources, with a first amethyst quarry project in Puy-de-Dôme (63).Learn more
The amethyst quarry St Joseph des Mines de Poux
Auvergne amethyst was occasionally extracted at least from the 17th to the beginning of the 20th century for its intense purple color.
It was one of the imperial and religious precious stones, and we now want to restore it to its place among the minerals of the world.
This is the first project based on our “micro-quarry” concept: a site of less than 3 ha, with optimization of extracted resources, processing techniques and impacts on the environment.
The transformation workshop
We have the ambition to recreate a modern place dedicated to lapidary art in all its forms (cleaning, shaping, rolling, polishing, cutting, engraving, faceting, etc.) in Auvergne, in a logic of resilience and involvement local.
We offer a whole range of products in 100% French amethyst, depending on the quality of the raw material, from decorative gravel to faceted gems. The first products will be available to order as soon as the quarry opens.See the catalog
The launch of the St Joseph des Mines de Poux quarry requires significant fundraising, and we are opening the project to investors. If you want to invest in a local company linked to the real economy, we are here to help.Learn more
