Coastal landscapes were a favorite motif.
Precious stones and stone vessels are some of the most valuable collector's items at any given royal court, and Rastatt was no different. The highlight of Margravine Sibylla Augusta's collection, however, were the pietra dura panels from the royal studios of the Medici family in Florence. Medici artists decorated furniture, small boxes and the walls of the family's mausoleum with these illustrative panels. Royal houses that became friendly with the family sometimes received such panels as gifts, as was the case with Sibylla Augusta, who received a large panel illustrating the annunciation.

The production method for such illustrative panels is called “commesso.” Stone slabs, sliced two to four millimeters thick, were cut into individual pieces that were then assembled into images. Gemstones were used for this work, such as agate, amethyst, lapis lazuli, or jasper, hard stones, from which the images took their name: “pietre dura”, Italian for “hard stones.” Granite and some kinds of marble were also used. The individual stones were selected with great care, for example to depict a cloud-covered sky.

Pietra dura panels adorn more than just the walls of the Florentine cabinet at Favorite Palace. Fifteen images have also been laid into the marble top of the large, luxurious table. In addition to three large coastal landscapes, the table also includes images of cherries, plums and peaches with delicate skins. Flowers and colorful birds—a robin, a goldfinch and a parrot—were also added. The panels are entwined with plants made out of inlayed mother of pearl.
Sibylla Augusta was related by marriage to the two children of the Grand Duke of Tuscany, Cosimo III de’ Medici. In 1719, returning from travels in Rome, she visited the family in Florence. While there, she is supposed to have ordered at least 85 pietra dura works from the grand ducal studio. They were also used in an altar in the Rastatt palace church.
