Early, 1940's, pre-eagle Mexican silver crown pin with faux green jade (or chrysoprase) and faux turquoise cabochons. The stones test as glass. It is signed Mexico Silver. This may have started out as a pendant as there is a raised round area on the back of the pin. One of the large cabs has a chip, you need to look closely to see it. There are also a few fleabites on the large stones. Otherwise the condition is excellent.
It measures 1.5 x 1.5 inches.
