Golden Silver Treasures Vintage French Sacre-Cœur Church Key Brooch B1762

A Sacre-Cœur (Sacred Heart) key brooch purchased in France. It is very delicate and in excellent condition. Its current color is a darkened patina, but it can be polished to a shine with a jewelry cloth. The material is sterling silver. 5x2 cm. Additionally, I'd like to share the safety clasp on the back with you all. This clasp is called a Trombone Clasp, and can also be referred to as a Push-pull safety clasp. This design is frequently seen in French and European jewelry. It was widely used in the 1940s, and even vintage Chanel pieces feature this design! You might want to check if any brooches you own have this feature? I think it's a wonderful design 😊 Due to their age, vintage jewelry should be stored in a resealable bag after use. Avoid wearing them during showering, swimming, or other water-related activities. With normal care, these pieces will last a lifetime.
