Colour depth and strength of dark-grey G654 granite

FORTEZZA Diorite is inspired by the famous Chinese G654 granite, known for its anthracite grey tone dotted with black micro-crystals.
This sintered stone solution reinterprets the classic sesame grey look with a fine grain texture that enhances floors, ventilated façades, stairways and plazas.
Its compact, uniform surface pairs visual rigour with advanced performance—ideal for high-end modern architecture and premium refurbishments.

Advantages of FORTEZZA Diorite:

  • Consistent colour: deep grey base and dark speckles remain identical on every slab, ensuring seamless large-format layouts.
  • Extreme structural strength: sintered technology withstands heavy loads, freeze-thaw cycles, marine climates and chemicals without extra treatments.
  • Design versatility: multiple formats suit public squares, commercial projects and minimalist interior walls.
