Bow-shaped brooch with a rectangular central stone and two rhinestones at the ends with a safety pin. It is probably made of potmetal, a metallic alloy composed of low melting point metals with metallic enamel on top.
Due to the style, the type of needle and the type of workmanship are probably from the 1940s when, due to the restrictions of metals due to World War II, it was common to make pieces with this method.
It measures approximately 5 centimeters.
The metal is NOT gold or silver so it can cause allergies if it comes into contact with the skin.
