This really tiny pin is vintage circa 1940s/50s? It is a Masonic piece and is fashioned from 10k yellow and rose gold, ruby and a blackamoor. It measures 5/8 X 3/8th of an inch and has the standard pin type back. The blackamoor carving is a mans face. I'm sorry I was unable to get a more clear view of it. You have to use a magnifying glass to see the detail clearly.
