Silver brooch by Reggers

This brooch was found in a thrift shop 2 years ago. The brooch is signed RR.
It's a brooch by Brothers Reggers (to be sure I had it appraised).
Definitely a keeper.

More on Brothers Reggers: Fons and Rein Reggers opened the firm brothers Reggers in Amsterdam in 1919. The brothers came from a family of goldsmiths that lived in the Dutch province of Brabant. At first, the brothers only worked with J.F. Hamburger, but it was not long until they made a name for themselves. They divided the work: Fons was the designer and Rein was responsible for the company's management. The company delivered its products to jewellers and art dealers. Reggers' jewellery was striking. The pieces are often made from silver and they usually have red coral accents. Characteristic of Fons Reggers' jewellery is the hammered surface and the a-symmetrical or curved lines. The jewellery's features are similar to that of the international Art Nouveau and the expressionistic shapes of the Amsterdam School. Since the company was very successful, it was able to use gold in their work after the war. They even started making clocks, candlesticks and altar rails. Reggers was taken over by Dutch Chainworks in 1960.
