Vintage Italian micro mosaic guitar brooch

This vintage Italian micro mosaic brooch, shaped like a guitar  reflects the long tradition of Italian mosaic craftsmanship that originated in Rome in the late 18th century.

Using tiny hand-cut glass pieces (tesserae), Italian artisans created detailed decorative designs that were especially popular as jewelry and souvenirs throughout the 19th and early to mid-20th century. Musical instrument motifs, such as this guitar, were favored for their artistic and symbolic appeal.

Based on its construction, signature, and style, this brooch is estimated to date from the mid-20th century (circa 1950s–1970s).
It represents a continuation of the classic micro mosaic tradition adapted for modern vintage jewelry.
