One of the pieces that were made around WWII, I believe, this Mexican silver and carved dyed calcite brooch is such a find! Shaped like a US Army officer's visor cap, complete with the appropriate insignia, it recounts part of the relationship the two countries had during those difficult times albeit in its jewelry version. The fact is that during WWII and due to the restrictions on the availability of metals which were dedicated to the war effort, many US jewelry manufacturers and big retailers had their jewelry made in Mexico. Coro had whole lines crafted at Hector Aguilar's workshop; Marcel Boucher's "Parisina" line was also made in Mexico; and it is said that Spratling was commissioned to produce dogtags for the American soldiers. The brooch at hand measures 2" wide by 1 3/8" tall and weighs 29.1 grams. It is marked "MADE IN MEXICO"and though not hallmarked for metal quality, it has been tested and is guaranteed to be silver of at least .900 purity even though I believe it's sterling. It dates in the 1940s and is in excellent vintage condition with nice color variation in the dyed calcite, very good definition in the army insignia, great patina, with no damage and no repairs noted.
