The new wall cladding within the elevators is comprised primarily of Fior di Pesco and Rosso Levanto marble. The stone has been affixed to aluminum honeycomb panels, making them lighter in weight and thus more suitable to use in elevators. The Fior di Pesco marble slabs are book-matched, creating a dramatic effect. Moreover, they are inlaid with Rosso Levanto marble that was intricately cut to form the silhouette of the Empire State Building's signature exterior form. “[This was] an extraordinary job; an example of the ability to use stone in places where one would hardly think to use it,” said Sergio Miglioranzi, managing director of Zanella, in reference to the project that took about one year to complete. Most of the large panels of Fior di Pesco stand 80 inches high and are 1⁄4 inch thick, set on aluminum honeycomb backing.

Miglioranzi said that the combination of marble, aluminum, epoxy resin and wood made the project complex. “Thanks to the [thin dimensions and light weight of the marble], it gives many advantages and opportunities,” he said. “However, it requires a great technical knowledge of the materials as well as a high level of technical skill in their applications.”
