Late XIX century brooch.
Technique: micromosaic, that is a mosaic made with very small pieces of glass paste.
Italy, around 1880.
Small pieces form the design with a swallow inside a rhombus, with two rows of pansy flowers on the sides.
There is a needle on the back for closing the brooch.
The Venetian-style micromosaic technique spread in the second half of the 19th century in Venice, following the revaluation and renewed interest in mosaics in the Basilica of San Marco in Venice, to which the master Salviati contributed in a particular way. The colors and subjects of the Byzantine style (or Venetian style) mosaics are different from those produced in Rome, which satisfied the tourist interest in the Roman archaeological monuments in the capital, often using black, red and green as backgrounds.
The state of conservation is good, there is no lack of pieces.
Slightly deformed the closure needle, but this does not compromise functionality.
