Round dining table in onyx and solid walnut by Osvaldo Borsani, 1950s.

This exceptional dining table is a rare and highly refined example of Italian post-war design, custom made in the 1950s for an important Milanese family closely connected to the Borsani circle. The table features a perfectly round top in Pakistani onyx, selected for its extraordinary natural pattern. The stone displays a rich, almost floral composition of deep green tones, translucent veining, and warm amber and ivory inclusions. The surface changes subtly with the light, revealing remarkable depth and movement, as clearly visible in the photos and video. The edge is finely finished, emphasising the natural luminosity of the onyx. The sculptural base is executed in solid walnut, expertly carved and shaped into an elegant, architectural structure. The legs flow organically into one another, creating a strong yet balanced presence that recalls the refined language associated with Osvaldo Borsani’s most sophisticated custom commissions. The walnut has developed a beautiful, warm patina over time, enhancing the table’s sculptural quality. With a diameter of 120 cm, the table offers ideal proportions for intimate dining while maintaining a strong visual impact. Its combination of noble materials, sculptural form, and bespoke origin places it well outside standard production, making it an extremely rare piece. This table is not only a functional object but a true statement piece — a unique work that embodies the intersection of Italian craftsmanship, architectural thinking, and artistic sensibility. Suitable for high-end residential interiors or important design collections, it stands as a testament to the quiet luxury and experimental spirit of mid-century Milanese design.
