TRIFARI MEDICAL CADUCEUS Brooch best

Fabulous Trifari brooch all done on brilliant rhodium plated metal. This is a first for me, I have never seen this with the numbers 2 5 on it! I don't know if it was specially made or what to commemorate an anniversary? Oh well the top or handle has clear chatons with the tail of the snakes wrapped best around all four chatons. The cross section of handle is clear chatons also. The snakes drop down from there and meet up with the blade which is all clear baguettes, below their heads are the 2 and the 5. Measuring 1 7/8” by 5/8”. RARE? ABSOLUTELY GORGEOUS!
