"Micro Mosaic Brooch XVIII Giacomo Raffaelli? A Decor Of Butterfly In Flight Silver Frame"ROMAN WORK CIRCA 1800
This brooch is probably in silver on the mount, a nice tarmac work and in the middle a nice micro-mosaic work, especially at the periphery and more a painted decoration at the butterfly level. Maybe a work of GIACOMO RAFFAELLI, but I cannot confirm it unsigned.
Everything was done with a pretty technique and great finesse. There is a whole set of micro-mosaics and some parts of the decor have been hand painted. We cannot say that the frames are in solid silver because we could not find a hallmark. But the quality of this jewel strongly suggests that it is silver.

Micromosaics The term micromosaics is used to designate a mosaic made up of tiny plates cut from glass rods, smalti filati or tesserae. An Italian chemist, Alessio Mattioli, developed in 1731 a composition of marble powder, linseed oil and pigments which made it possible to obtain a flexible stretchable material in long and fine rods cut into small pieces. The infinitely small smalti allowed the micromosaic to compete with painting. To fix them on the glued support, the mosaic artist uses tweezers, the elements cut from spun glass rods measure only a few millimeters. The greater their number, the more quality the object and the pictorial rendering. The assembly of smalti fixed on a rigid support is polished and waxed then inserted in a frame of black glass or onyx and finally set in frames in yellow or silver gold. The micro mosaic knew its golden age between the end of the 18th and the beginning of the 19th century. It was in Rome that she was born, Giacomo Raffaelli (1753-1836) was one of the first to work in "mosaico in picolo", his workshop was located in the Spanish Steps and it was at his home that he had the first exhibition took place in 1775. In 1820, there were more than twenty workshops in the city. Following Rome workshops are created in the main cities of Italy. The works using this manufacturing process are for many of the travel souvenirs brought back by young people, collectors and lovers of works of art from the European upper-middle class, who at the end of the 18th and beginning of the 19th began their "Tour in Italy". Thanks to these travelers, micromosaics circulate in France, England and Russia. The works in micromosaic are also presented during universal exhibitions of the XIXth century, they know an immense success and are acquired by a clientele of connoisseurs, by European sovereigns and collectors notably Anglo-Saxons. We find these micromosaic plates on boxes, jewelry: brooch, button, earrings, necklaces but also on vases, pendulums, table tops ... They are mounted in Italy but also exported. Foreign jewelers and goldsmiths adapt them to their own production.
