Vintage R.M. Made in Italy Floral Micro Mosaic Brooch

This is a beautiful vintage micro mosaic brooch stamped Made in Italy R.M. The metal has tarnished, and the silver-tone color has largely worn away revealing a brass base metal. The mosaic itself could use a thorough cleaning. Additionally, there is some minor green tarnish on the front. Overall, the piece is still in very good condition. Approximate Dimensions: 1.25in x 1in
