Crinoids – traces of fossilised aquatic fauna and flora - are its guaranteed special features. Their visible presence is proof of the unique character and authenticity of the blue stone, which is much more resistant than other stones with similar appearance.
The blue limestone of the Carrières du Hainaut® is extracted and processed on one single site in Belgium, at Soignies. The complete exploitation process of Carrirèes du Hainaut® is homologated by a technical certificate provided by the Belgian Union for Technical Approval in Construction (ATG).
