I've found a few pages that have history on the Trifari brand of
jewelry as well as offer some pieces for sale. This way you can get
an idea of how much they are worth - and you may see a similar brooch
to one of yours as well.

Enchanted Learning: Trifari Jewelry
A short history with some pieces pulled out to describe (with photos, of course).
"Trifari: Luigi Trifari was a top goldsmith in the mid-1800s in his
native Naples, Italy where he had a small but successful workshop.
Gustavo Trifari, Luigi's grandson, was born in Naple sin 1883 and
learned the goldsmith's craft from his grandfather. In 1904, Gustavo
emigrated to America and found work as jewelry designer in New York
City. In 1910, he partnered with his uncle and founded his first firm
Trifari & Trifari to produce high quality costume jewelry. Two year
hence, Gustavo went on his own and formed Trifari which he operated as
owner and designer until 1917 when Leo Krussman joined the company as
sales manager. The company Trifari and Krussman was incorporated in
1918, and after top salesman Carl Fishel joins the company in 1923 the
name is changed to Trifari, Krussman, and Fishel. The 1930s were a
period of outstanding production for Trifari with Alfred Phillipe as
their lead designer, formerly of Cartier and Van Cleef & Arpels. Under
his imaginative leadership and with runaway successes such as the 1941
"crown" pin, Trifari grew to become the second largest U. S.
manufacturer of costume jewelry behind only Coro. Trifari leveraged
the services of many popular designers including Jean Paris
(1958-1965), Andre Boeut (1967-1979), and Diane Love (1971-1974), and
Alfred Phillipe stayed with the company until 1968. With these diverse
design contributions, Trifari produced an incredibly wide array of
styles at all different price levels, but they all enjoy the excellent
craftsmanship which Gustavo learned from his grandfather. Most Trifari
pieces are marked with a crown above the "T", or in variations "TKF"
or "Trifari, Krussman & Fishel". (Reference Source: Masterpieces of

Here are pages that just have items for sale:

I found these websites by doing a search of the Google database
(www.google.com) for "Trifari". There are a ton of sites out there
offering Trifari jewelry for sale - if you have a specific piece
you're interested in evaluating you might search for it using some
words describing the piece, plus "trifari".
