    • 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.
    • Bone


      With a uniquely rich cream tone, the Bone finish exhibits a dense, subtly clay-like texture, ensuring both durability and a distinctive tactile quality. Crafted from highly durable UV resistant powder-coat, Bone
      allows precise shaping into geometric contours, mirroring the appearance of a glazed enamel and delivers an unexpectedly cool touch. The tone, thoughtfully chosen, imparts a sense of warmth and timelessness, harmonising effortlessly with various materials, from marble to metals, to create a versatile and cohesive palette.

      Care:

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

      Caution:

      Whilst this finish has a highly durable powder-coated application, if this becomes damaged, the solid forged brass is still very durable.
