Superb little knife-shaped brooch with a little insect (a fly) on top, in yellow and white 18-carat gold, fly with a small pearl, a red stone (perhaps a rubellite) and small Roses, stamped eagle head, from the 20th century.
This pin is in good general condition. It is punched in two places.
Remember: it will be clean, micro-scratch and tiny wear time, see photos.
