Brief historical context
The house was founded in New York in 1918 by Gustavo Trifari, later joined by partner Leo Krussman and salesman Carl Fishel. From the early 1930s, Alfred Philippe joined as chief designer (coming from fine-jewellery experience at one of the great Parisian houses); under his artistic direction, the firm defined its signature style and the so-called "jewels of fantasy" (fruit and flower reliefs, animal figures, calibré-like settings in gilded metal with clear rhinestones).
In the same period, the house gradually introduced the well-known "Crown Trifari" mark: a small crown above the firm's name, initially as a patent marking, later as a permanent signature. The Philippe period lasted until 1968; after that, artistic direction changed several times and part of the production moved outside the United States during the 1970s and 1980s. For the vintage market, American production until approximately 1970 is considered the core, with the years 1935–1955 as the peak.
