This form of mosaic work, typical to Florence, Italy, does not use regularly shaped pieces of stone, tile, or glass to form a design the way many other mosaics do. Rather, artists fashion pictures out of thin, irregularly shaped slices of stone.
Selle mosaiigitüübi puhul, mis on omane Itaalia linnale Firenzele, ei kasutata aga korrapärase kujuga kivi - ja klaasitükikesi ega kahhelkive, nagu on tavaline teiste mosaiigitüüpide puhul, vaid eri kujuga õhukesi kiviliistakuid.
