Franco Caruso explained that the Province of Ragusa has been known for its limestone for over a century, and it developed into a solid stoneworking region. However, during the course of the 20th century, some local companies were losing business to the growing stone industry in Carrara, Italy. As a result, fabricators traveled north to Carrara to re-learn the trade, and ultimately moved back to Ragusa. Consequently, the region now has a multi-stone culture, and Comiso is developing international renown as a block-processing center. Today, Caruso has grown to a company with over 150 employees.
On the quarrying end, Caruso extracts “Petra di Comiso†limestone from its own quarries in Ragusa. Stone is extracted from traditional above-ground sites as well as an underground site.
