Pietra Dura is a mosaic art practice that developed by Ancient Romans, Opus Sec-tile technique. The Pietra Dura technique became popular amongst mosaic designers, since it flourished in Florence in the late 16th and 17th centuries. The technique involved a style of vastly illusionistic illustrations, using cut-to-shape colorful tiles of hard stone. The term Pietra Dura signifies the vital hardness and resilience of the material used for this work. The most common stones used in Pietra Dura Mosaics are the stones with high mohs scale of mineral hardness. Quartz, chalcedony, agate, jasper, granite, porphyry, and petrified woods are frequently used in Pietra Dura mosaics. These stones vary and endow with an almost boundless range of colors.
