About Us

SZ Minéraux, A story, A lot of passions

Her and Him and More...

We are Cédric and Mathilde, SZ-Mineraux .

Cédric, 38 years old, passionate about fossils and minerals since my earliest childhood when I went to look for fossils in the fields with my father and my friends. I completed my studies in two stages: mechanical engineering first, then Geosciences on Nancy. I combined these two specialties to create my company for the sale of collectible minerals and custom base.

Mathilde, 33, at the bank advisor base, I decided to devote myself 100% to the company since September 2019. For the last 15 years, I have been participating in trade shows, sales, online marketing, bases, etc. Two full-time jobs.

But with the arrival of our little Trystan, we had to make a choice and he naturally turned to mineralogy.

We have been together for 15 years and share the same passion. We started selling 14 years ago through a self-starting company; and we have evolved to the status of SARL 7 years ago because we realize in addition to the sale of collection minerals of customized bases. Indeed, to allow an optimal enhancement of your specimens, we realize bases where there is no need for glue or adhesive paste to hold your piece.

You can find us on the world’s biggest stock exchanges (when they can resume!): Tucson, Munich, Sainte-Marie-aux-Mines. And in various in France or abroad: Paris Charenton and Marriott, Lyon, Millau, Switzerland, Germany, etc.
