Black onyx marble gives the Frontier Tray its striking visual presence. Layers of deep charcoal and soft grey veining move across the stone in natural bands, creating a surface rich in depth and tonal movement. The rectangular form is softened by gently rounded corners, allowing the material to remain the focal point of the composition. Each tray is carved and finished by skilled artisans, revealing the unique character of the stone beneath its polished surface. The marble’s natural veining ensures that no two pieces are identical, while the smooth finish enhances the contrast between dark mineral tones and lighter striations.
