Here's a large brushed goldtone pendant by Trifari, and being from the 1960s, I can envision it with a polyester leisure suit!
This large pendant looks like a fan and is ornate. The twisted rope chains are large and measure 5mm wide. Both chains are attached at the spring loaded c clasp. The longer chain measures 29" and the shorter, which the pendant is suspended from, measures 19". The pendant is hallmarked on the back Trifari.
Regarding the condition, the pendant is perfect and looks new. The chain shows a little wear where the pendant is suspended from, but could easily go unnoticed.
