Vintage Italian micro mosaic pendant necklace.

These intricate pieces feature tiny, hand-set glass tiles called tesserae arranged into traditional floral patterns—often depicting daisies, roses, or forget-me-nots. This specific design features an oval main medallion with a gold-tone or brass filigree border and two dangling teardrop charms. Jewelry of this style was famously crafted in Italy (often in Florence, Rome, or Venice) and widely collected as souvenirs from the Grand Tour era through the mid-20th century (roughly the 1920s to 1950s).
