Workshop for Hard Stone

The "Workshop for Hard Stone" (Opificio delle Pietre Dure) was established in Florence, Italy, in 1588 by Ferdinando I. This workshop specialized in commesso, an art technique developed in Florence in the late 16th century. Commesso involves creating pictures using thin, precisely cut pieces of colorful semiprecious stones, often referred to as "hard stones." These stones include agates, quartzes, and lapis lazuli. The resulting artworks, used for tabletops and wall panels, could rival paintings in their detailed realism, depicting subjects from landscapes to floral designs. The workshop was primarily tasked with creating decorations for the Medici family's funerary chapel and continued to operate as a state-supported institution into the 20th century.1
