Micromosaic Jewelry

Modern micromosaic pieces just can't compare to the laborious and painstaking art form that was 19th-century micromosaic-making. They were a particular specialty of Rome, coming to the height of their popularity around 1800-1870. In those times, a micromosaic could be composed of anywhere between hundreds and thousands of tiny pieces, each applied skillfully by hand using a pair of tweezers, to create impressively intricate and beautiful scenes.

The Making of Micromosaic Jewelry

Micromosaics are miniature mosaics made using what is called 'smalto' or 'smalti' - opaque vitreous glass or enamel that comes in a wide variety of colors and replicates the appearance of a non-reflective painted surface. The material is melted and pulled into rods or threads, called 'filati' (spun enamel). Once these rods or threads have cooled, they are cut into hundreds of tiny cubes, known as 'tesserae'. The tesserae are then arranged in a copper or gold tray into the desired scene or image.

The base of a micromosaic piece is usually made of either metal or stone (with black Belgian marble, 'Noir Belge', being a popular choice). These are then filled with mastic or cement, and the tesserae are carefully arranged on top of this using a pair of tweezers and a great deal of skill and patience. Once the mastic or cement has hardened, the gaps between the tesserae are filled with colored wax and the whole picture is polished to achieve a smooth and even surface. Micromosaic pieces intended for jewelry were often oval or circular plaques set into pendants, necklaces, earrings, brooches, and rings. The pieces were often made in Rome and then exported to London or Paris to be mounted in jewelry.

The art of micromosaics is said to have originated at the Vatican. When some of the famous paintings in St. Peter’s Basilica began to deteriorate due to damp clouds developing, thoughts turned to the mosaics of ancient Rome that had retained their color and impact for thousands of years. Vatican artists began to experiment with ways of replicating the damaged paintings using mosaic techniques, eventually managing to create some 28,000 different hues of tesserae to do so. By 1770, nearly all of the paintings in the basilica had been replaced with almost indistinguishable mosaic copies, built to last. Soon afterward, some of the artists who had been involved began to apply their skills to making miniature mosaic art using teeny tiny pieces of tesserae - portable artworks that could be sold to the private market and set into jewelry.

Via Walks in Rome

It's believed that micromosaic jewelry went out of style in the late 19th century when the huge demand for such pieces saw an influx of workers to Rome who weren’t skilled in the art and began making poor quality versions. These low-quality pieces flooded the market and damaged the industry significantly.

Pietra Dura

While micromosaics in their traditional sense originated in Rome, another kind of micromosaic known as 'pietra dura' - literally 'hard stone' - was becoming popular in Florence. Although they are often included under the umbrella of micromosaics, the key difference between Florentine pietra dura and micromosaics from Rome is the use of bits of polished and thinly sliced stone, carved into specific shapes and fitted together like a jigsaw puzzle, instead of glass or enamel tesserae. These were often set into marble and framed with metal. Artisans would use semi-precious stones like agate, lapis lazuli, jasper, and chalcedony as well as stones like malachite, carnelian, and quartz, which mimicked the delicate webbing and color shifts of wings and petals - creating stunning visual illusions.

When Florentine micromosaicists began to favor more brightly colored and striking materials like turquoise and mother of pearl, the pieces lost a lot of the depth and realism that they had been loved for, and soon fell out of fashion. That's why the materials used in pietra dura pieces can often be used to date them and determine their value.

The Grand Tour

With the end of the French Revolution and the Reign of Terror, and the revolutionary wars surrounding this, it was finally safe to travel again to the Continent. This also coincided with an increase of wealth across Europe and a growing merchant class, meaning that travel to Europe was no longer limited to the upper classes and aristocracy. Soon, British and American tourists flocked to Europe's cultural capitals - Paris, Rome, and Florence - on what was known as the 'Grand Tour'.

The 'Grand Tour' became a kind of right of passage for nobility seeking to improve and expand their education. They went to these places in order to soak up the culture and history there, and it soon became extremely fashionable to send or bring back souvenirs and mementos from these lengthy trips. A particular favorite for Grand Tourers were beautiful, portable pieces of micromosaic jewelry, many of which were made expressly for this purpose. By 1817, the Scottish traveler Charlotte Eaton recorded that there were 'hundreds of artists, or rather artisans, who carry on the manufactory of mosaics on a small scale' around the Piazza di Spagna.

With the origins of micromosaics in the Vatican, some particularly wealthy tourists could even gain themselves custom micromosaic pieces from the papal jeweler if they made a substantial enough donation to the Catholic Church.


Some of the most common pieces of micromosaic jewelry featured famous Italian landmarks such as the Colosseum and St. Peter's Basilica, as well as figures from ancient Roman mythology and scenes of bucolic Italian peasant life. Many were also inspired by famous paintings by the Old Masters or contemporary landscape paintings. However, the most sought-after and possibly the most impressive pieces (in my opinion) are those depicting flowers, birds, and other animals.

Motifs from Antiquity

Pair of gold and micromosaic bracelets and a brooch, each depicting Cupid in a chariot drawn by deer, lions, or doves, surrounded by frames of gold cannetille, joined to clasps of rose motif in silver, rose, and yellow gold, c.1800-1830. Via Sotheby's

Micromosaic chariot pulled by butterflies, c.1800. This high-quality micromosaic was most likely the top of a metal box and was later turned into a pendant. The lid is marked J.COLA for Giacinto (Jacinto) Cola, one of the best mosaicists active in Rome at the beginning of the 19th century. Butterflies are a common representation of Psyche, while Cupid is frequently shown with wings and his symbols are the arrow and torch, "because love wounds and inflames the heart." This depiction is unusual because Cupid is represented by a bird, but the torch in the chariot would be symbolic of Cupid

Doves of Pliny

An important early inspiration for micromosaics, both in terms of subject and technique, was the 'Doves of Pliny'. This was an ancient mosaic made of marble tesserae, discovered at Hadrian’s villa outside of Rome in 1737, and is one of the finest examples of an ancient mosaic ever found. It was actually a Roman copy of an even earlier work by Sosos, a Greek artist (2nd century A.D.).
