www.calamini.itinfo@calamini.it Urbano Calamini Urbano Calamini started his business in the 70’s, when the quarrying activity was only

restricted to the outcropping layers due to the greater facilitations during the ̒ uncoveringʻ process. Once quarried, the stone was therefore sold ore and untreated. In order to support the production of Pietra Serena, accounted as a valuable cultural identity material in the Tuscan area of Firenzuola, Calamini opened up a small lumber factory and a workshop, where he began working the ore stone blocks coming from Ricavoli and Della Guardiola Quarries. Throughout the years, also thanks to his sonsʻ entry in the business, the Calamini Urbano Company has been greatly enhancing and specifying its services in response to the increasing demand of Pietra Serena products. The quarrying activity of Pietra Serena only takes place within the company-owned quarries and the ore material is entirely worked within the Calamini factory.

Pietra Serena

Pietra Serena (Florentine Macigno Stone) is the great material which best represents and symbolizes the Tuscan cultural and architectural heritage. Pietra Serena is, in fact, the most traditional Tuscan stone; first used in local rural building, it has been gradually crossing its original geographical borders and has been gaining a new aesthetic value throughout the centuries. It is now considered as one of the greatest architectural and ornamental material and may be used for the most innovative applications. The reinterpretations of the peculiar properties and performances of Pietra Serena place it within a modernization process according to its several purposes, either structural and ornamental.
