Gold and silver baby classical Art Nouveau period classic floral line lady pin brooch French b1776

Super beautiful Art Nouveau lady's brooch purchased from France. Classic ladies, sinuous lines and shapes combined with plants and flowers are the main features. The material is Silver, not sure if it is sterling silver, it was originally very dark, but after being wiped with a jewelry cloth, it quickly became brighter. Thick and in very good condition. The back is an old fashioned buckle. 3x2.5 cm. In addition, I would like to share with you the safety buckle on the back. The name of this buckle is Trombone Clasp, which can also be called Push-pull safety clasp. This design is often seen in French jewelry and European jewelry. It was widely used in 1940, even old Chanel had this design! Can you check if the pins you have have such a device? I think it’s a great design 😊 Due to the age of antique jewelry, please store it in a zipper bag after use. Do not wear it for showering, swimming and other water activities. Normal use, long life.
