GMC SpA – Since 1973, excellence in Natural Stone.

Since 1973, GMC SpA has been successfully operating in the marble and granite industry, earning a solid international reputation.

With two main locations in Luni (SP) and Massa Carrara (MS), and a strategically placed warehouse in Affi (VR), the group is at the heart of marble excellence.

We own a Bianco Carrara marble quarry and are the exclusive owners of the quarry where the renowned “Breccia Capraia®” marble is extracted.

Alongside our own materials, we carefully select premium Italian and international marbles and granites to offer a wide and refined range of natural stone solutions.

We manage every stage of the production process, from quarrying to final processing in our workshops.

A highly skilled team oversees each phase, ensuring consistently high quality standards and outstanding results.

Our team works closely with leading architects and design studios, providing bespoke solutions and special processing for even the most complex projects.

GMC marbles are featured in prestigious international projects across Asia, the United States, and the Middle East, confirming the quality, reliability, and excellence of our materials.
