KM Stone is the result of the development of CBM Natural Stones, which has been successfully active for more than a decade in the most important construction projects in Switzerland with its brand KM Pierre NaturelleTM. We offer in our showrooms in Switzerland and Italy a wide range of marble, granite, travertine and onyx, timeless refinement elements necessary for any building project wishing to stand out. KM Stone guarantees an integrated quality control, including a strict quarry selection, SGS® frost resistance tests for its natural stone for outdoor use, careful packaging and on-time delivery of orders both in Switzerland and abroad. Our stones are processed with proven machines and technologies that enable our customers to carry out their construction projects accurately and confidently.


KM Stone was established with the ambition of offering the most varied choice of natural stone, relying on partners with a proven reputation and experience who master the selection and production directly in the quarries and factories. We offer our customers a direct relationship with the quarries and production units so that they can carry out their wishes as faithfully as possible. We are at your disposal to suggest the best options for the choice of natural stone, from the project to the finalization of your projects.
