THE T-BAR PIN AND C-CLASP
THE TROMBONE CLASP
Named after the trombone-like gesture required to pull open the tube shaped closure, Trombone clasps were also used during the late 1800s. They are most often found on European made pieces. This type of clasp can sometimes be found on European jewelry from the 1940s as well.
THE SAFETY CLASP
Around the 1920s the modern fold-over safety clasp was invented. This helped secure the heavy jewel encrusted pieces of the time. This also made brooches more functional for the modern woman, as it helped keep the brooches protected against her new more active lifestyle.
