Perli Germany

Perli Werkstätte, founded by Martha May in Schwäbish-Gemund in 1922, switched from manufacturing faux pearl jewelry to cloisonné enamel in 1935.... Matte enamelled silver or copper jewelry for men and women were signed "Perli Made in Germany", sometimes "handarbeit" (hand-crafted.) The counter-enamel could be glossy black or speckled grey. The Germans preferred the cloisonné matte enamel technique where the cloisons wires are soldered on the copper or silver base which separates the colors. The resulting cells are filled with enamel and buffed flat. Hydrofluoric acid applied to the surface produced the matte effect in the 20th century.
