A Florentine is made of semiprecious stones and is an ancient craft which began at the end of the 6th Century in Florence. It was an evolution of the craft of using mosaic tiles to create more and more refined, painting-like mosaics. The materials are different from those used in mosaic tiles, using semi-precious stones like Lapis lazuli, Chalcedony, Jade and opaque precious stones. These are cut into thin plates and then carefully and precisely shaped before being positioned next to each other and glued onto a support. The final polishing of the work is crucial, and this is still done by hand, enabling the beauty and iridescent colours, streaks and stains in the stones, to shine through.
