The avant garde jewelry of Arnaldo Pomodoro (b. 1926), like his sculptures, tends to explore worlds of other dimensions. Both Arnaldo and his brother and collaborator Gir were trained at the Istituto Tecnico per Geometri in Pesaro, Italy, and continued on to become prominent leaders of the Italian avant-garde. Arnaldo employed himself as a set designer, sculptor, and printmaker, bringing together many of these talents in his jewelry production. By 1960, his work was often described as Abstract Expressionist, due to his grand scale mechanized bronzes with deliberate gouges suggesting deterioration. The basic shapes he employs, such as magnificent cylinders, cubes, and spheres, are sometimes presented as decaying ancient acropolises. Arnaldo's enormous geometric shapes are disrupted abruptly by erosion-like subtractive sculpture appearing as an earthquake fault or the remnants of an abandoned excavation. A perfect sphere appears to be in a state of decay, almost as a metaphor for a decaying planet. Such imagery derives itself from Arnaldo's interest in the earth's surface. The geological formation of craggy rocks and mountains and the rustic landscape of Pietrarubbia, a location near his childhood home, are great inspirations for such imagery. His silver metal pendant resembles stalactites and stalagmites magnificient geological products.
