Rare Polyhedral Trinket Box by Pietro Chiesa for Fontana Arte, ca. 1940s

This exceptional sculptural box exemplifies the perfect synergy between mid-century Italian craftsmanship and avant-garde geometric abstraction. The object features a complex, multifaceted polyhedral body crafted from a sophisticated marquetry of warm walnut wood. The dynamic interplay of the contrasting wood grains accentuates the sharp, architectural facets of the base.

The monumental wooden structure is crowned by a heavy, thick-walled crystal glass lid in a subtle sea-green hue. The glass is masterfully ground and bevelled to catch and refract light—an unmistakable signature of the prestigious Milanese manufacturer Fontana Arte during the artistic tenure of Pietro Chiesa. This rare collector's piece seamlessly bridges the gap between functional luxury and pure geometric art, serving as a prime example of high-end Italian modernism.
