Vintage Millefiori-Style Glass Brooch

This vintage brooch is made of a gold tone metal and has a pin barrel closure, which is unusual. The front of the brooch has a detailed gold border and features a millefiori-style glass center with pink and blue flowers on a red background. The brooch is not stamped, and I could not identify the maker. There is some normal wear, but this piece is in good condition overall. Dimensions: 30mm x 25mm Weight: 8.77g
