Joe Colombo “Biglia” Ashtray/Round Box for Arnolfo di Cambio, 1969, Signed

This rare and elegant piece is a testament to Joe Colombo’s visionary design and mastery of form. Crafted from Alexandrite glass, renowned for its ability to change color depending on the light source, the “Biglia” subtly shifts between shades of blue and violet, evoking a sense of mystery and intrigue with every glance. The thick, semi-spherical glass orb, which rests atop a finely silver-plated circular compartment, is not only a striking aesthetic feature but also serves a dual function. The orb can be used as an ashtray, while the silver-plated section below doubles as a refined box for storing jewelry, small treasures, or keepsakes. The hallmark on the silver plating further attests to its authenticity and quality.
