Grigio Avio

Product overview

Accademia Grigio Avio

Accademia draws inspiration from the most beautiful marble works that the artists of the past have bequeathed to us and the most precious artistic expressions created and preserved through the language and sensitivity of the greatest creativity of history.
The collection interprets the natural marble, preserving and enhancing the essential beauty of the original noble material thanks to the technological excellence of the production process and the creative approach.

Our Design team takes inspiration from exquisite natural marbles and stones in order to create new design by harmonizing and perfecting the original qualities of marbles. The result is unique new sintered marble design with excellent technical features and superior aesthetic which are human made but seems shaped from nature. Being one of the few using the precious dry-granula on the slab surface, Nexion team has devised a superior mirror-like , distortion free surface to enhance the original properties, color nuances and details of the natural marble with an unparalleled reflection.


We offer the broadest range of surfaces.
