Your work of art.

About us

About us

At Unique Onyx,
we look for uniqueness in the block and from there create a solid rock.

Our projects

Technique and knowledge

Vert d’Evolène, Vert des Glaciers, Pierre de Saxon, Verde Andeer, San Bernardino, Calcaire du Jura (N.B. all from our local area!) , Patagonia, Mont-Blanc, Taj Mahal and Azul Macauba quartzite, Carrara and Macchia Vecchia marble… — This is stone. Sometimes it comes from far away, sometimes it simply crumbles from the mountain opposite. And sometimes it is simply there, under our feet. Where it comes from doesn’t really matter: whether it is from Italy, the Amazon or Switzerland — like us — Unique Onyx will pay homage to the stone’s natural size to the finish, from the early stages of your project until it is fully realized, for you. Marble, granite, limestone, quartzite, onyx. Or onyx, quartzite, limestone, granite, marble? For bathrooms, spas, groundwork, work surfaces, bars...? ... For everything. Yes, for whatever you like! The only rule: bring your visions to life. Your unique visions. At Unique Onyx, we select, design, cut, sand, model and enhance. Then we install, adapt, care and maintain.

With you:
We look for the stone. 
We select the piece.
We assess the quality at each stage of production. 
We install everything.
Then we ensure that our stone,
your stone, is maintained and built to last.
