How do you identify a Trifari brooch?

To identify a Trifari brooch, turn it over and look for a maker's mark. Most Trifari jewelry features one of several backstamps. The earliest pieces made by the American jewelry brand usually read "KTF," for Trifari, Krussman, and Fishel. During the early 1930s, the stamp changed to "TRIFARI PAT.PEND.," and in 1937, the company introduced its crown logo. Pieces dating from the mid-1950s to the mid-1980s will bear this logo plus a copyright symbol. Finally, the 1980s brought the addition of a “™” trademark marking. If you can't find a stamp or have difficulty reading it, you may wish to consult a certified appraiser or other knowledgeable expert. On 1stDibs, shop a range of Trifari brooches.
