TRIFARI MEDICAL CADUCEUS retailer Brooch

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 around all four chatons. The cross section of retailer 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!
