    • 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 marble's appearance.
