Gustavo Trifari, an Italian, learned the jewelry business from his grandfather. In 1904, he immigrated to the USA to earn his fortune and start a new life. He partnered with his uncle, Ludovico Trifari to produce a company called Trifari and Trifari in 1910. Two years later, Gustavo left this business to start his own business which specialized in accessories. In 1918, he partnered with Leo F. Krussman and founded the Trifari and Kussman company. Krussman was the marketing man and Gustavo was the designer.
The next step in the Trifari partnership came in 1925, when the two men combined resources with Carl Fishel to form Trifari, Krussman and Fishel. The jewelry marketed by this company used the mark KTF with a taller T than the other letters. (There was also a line stamped KTF with a crown over the T made in 1954, but it is not as valuable as the earlier KTF pieces.) These early KTF pieces are very rare and hard to find.
Between 1930 to 1968 Alfred Philippe was the top designer for Trifari jewelry. He had formerly been a designer for Van Cleefs and Arpel, so he came with a rich designing history behind him. Beware - many online sellers label any early Trifari designs as Alfred Philippe designs, when this is not the case. Some of his early designs are marked Trifari Pat. Pending and a patent search will give the design specifications.
Trifari introduced a very successful line which they called "Jewels by Trifari" in 1938. A few years later, metals became scarce for manufacturing jewelry, due to the war, so Trifari used Sterling silver for many designs during this time. A few years later, in the 1940s, they patented a plating process called Trifanium. This plating method made the material look like real gold or silver and helped to maintain the condition of the metal over time. Trifari pieces are extremely well made and continue to stay in wonderful condition generations later.
One of the most well known and collectible of the Trifari pieces are the Lucite Jelly Belly pins. Once again, many jewelry sellers market a wide variety of jewelry as jelly belly, but true Jelly Bellies have DuPont lucite clear acrylic bellies. These pieces are figurals, such as birds and fish and are very rare and highly valued.

Trifari continued manufacturing during the 1950s and 1960s. After this, it traded under the names a variety of companies. The company was sold to Hallmark, Inc in 1975 and then again to Crystal Brands Jewelry Corporation in 1988. Finally, in 1994 it was purchased by a division of the Monet group. This group was finally sold to Liz Claiborne industries and Trifari jewelry continues to be made by this company, although the jewelry is no longer manufactured in the United States.
Here are some markings you may find on Trifari jewelry. I've listed them in chronological order so that you can see the progression of hallmarks over the course of the manufacture of Trifari jewelry.
The earliest designs are, of course, the most collectible of all the Trifari designs, but don't overlook more recent pieces. All Trifari jewelry is exceptionally well made and beautiful.
