    • Portoro Gold

      With a rich and intricate grain pattern set against an onyx backdrop, Portoro Gold is a highly coveted stone. Characterised by crystalline geometric forms, this material brings visual and tactile complexity. Portoro Gold is reimagined for a modern aesthetic, creating a striking contrast with other materials in the collection. As with all natural materials, expect a beautiful variation in both degree and tone of veining, making each piece truly distinctive.

      Care:

      This finish has been treated with a high-quality German-made external-rated sealant. To preserve the finish use a cleaning product specifically designed for stone surfaces.

      Caution:

      Promptly remove stain-causing materials from dome surfaces to maintain the marbles appearance.
    • Smooth Nickel


      Soft to the touch yet stark in its industrial aesthetic, Smooth Nickel is a truly unique and distinctive finish. To achieve this finish, nickel-plated forged brass is very lightly linished, before being plated with Smooth Nickel. The result is a sleek and commanding finish that invites touch. Eye-catching in its distinction, Smooth Nickel sits as comfortably among lush timber as it does harsh concrete.

      Care:

      Clean it regularly with a damp soft cloth and be sure to keep it dry.

      Caution:

      Whilst this finish has a lacquer layer applied, if this becomes damaged, the pearl nickel layer underneath is still very durable.
