Trifari Gold Tone "Trifanium" Leaf Choker/Circa 1950's -60's

I got to pick through the box of tangled necklaces at Salvation the other day while helping my friend sort things out. Out came this Trifari choker in a goldtone "Trifanium" leaf pattern. I've seen these in many different designs and colors and as part of a set but sadly there was nothing else. It's in nice condition but is missing the tiny little ball at the end of the chain extension. It's articulated every few links to help it lay flat against the neck line and it's quite heavy. There is a very tiny "Trifari" mark on the underside of the clasp. -Mike-
