Millefiori Mosaic Brooch - buying Late 19th. C.

Many fanciful flowers in a glass mosaic oval within a flowered silver bezel with a silver on brass locking clasp. No origin or metal identification marks, so these are my opinions. Usually this type of jewelry is designated as Italian, although this is a more delicate composition than is typical. 1 5/16" w. x 1 1/16" h. x 3/8" d. (Crochet pin cushion not buying included.)
