"Perli Werkstätte, founded by Martha May in Schwäbish-Gemund in 1922, switched from manufacturing faux pearl jewelry to cloisonné enamel in 1935. Perli pieces were exhibited in the 1937 Paris Exposition Internationale. Matte enamelled silver or copper jewelry for men and women were signed "Perli", sometimes "handarbeit" (hand-crafted.) The counter-enamel could be glossy black or speckled grey." Background info found on the net
This particular brooch does not have the usual enamel or the heavy modernist 1970s silverwork.
It is therefore hard to date. I was not able to find a similar example.
It is signed Perli 800
I only guess it may be an early example as it is in the arts & crafts style, so 1920s-1930s.
Please correct me if I am wrong.
It has very beautiful fine hammered silverwork and silver wire leaf pattern
It is in Very Good Vintage Condition and as found: Not polished
