GMC SpA has been operating since 1973 in the marble and granite sector.
The GMC Spa group consists of two major companies with offices located in Luni SP and Massa Carrara (Italy).
The scrupulous selection of marble and granite and the attention in the entire production process are our key to success on world markets.
From quarry extraction to downstream transport in the laboratory, highly qualified staff accompanies and transforms marble throughout the entire processing chain.
The production ranges from simple paving tiles to large open-stain slabs for prestigious interior finishes and luxury finishes.
Our marbles are: Bianco Carrara, Statuario and Calacatta GMC, Arabescato and we are owners of 2 quarries from which we produce BIANCO CARRARA and BRECCIA CAPRAIA.
The many years of experience in the field of natural stone has allowed us to acquire an important know-how in interior and exterior design.
The Company GMC SpA has significantly improved its technical department thanks to which even large projects can be realized and delivered quickly.
At the disposal of engineers and architects our staff performs various types of cutting to size and inlay processing. GMC Spa is involved in projects all over the world.
From the Asian continent to America, passing through the Middle East, it is easy to find structures, important constructions where our marble or precious granite is present, as well as our exclusive Breccia Capraia material.



The Breccia Capraia quarry is located in Tuscany, in the heart of the Apuan Alps, in the province of Massa-Carrara, between the Altissimo and Carchio mountains.

Nature has created an exclusive material:
