CHIARAMONTE GULFI (RAGUSA), ITALY - 19 MARCH 2019: Tiles of Pietra Pece are seen here in the Artigianto Industrialre manufacturing plant in Chiaramonte Gulfi (Ragusa), Italy, on March 19th 2019.
The pietra pece (pitchstone) is a type of limestone which is charachterized by different percentages of bitumen.
This morphologic origin makes the pietra pece particularly unique for its peculiar chromatic shading.
In fact, the pietra pece is also called "asphaltic stone" because it has a colour that varies from gray to dark brown.
The company DESCAT has been the owner of the registered trademark of the pietra pece since 2014 and it has the ownership of the only extractive pietra pece quarry situated in the Tabuna/Cortolillo district in Ragusa, Sicily. The pietra is distributed by Artigianato Industriale.
