This sterling silver brooch is a mid-century twist on the classic Aztec sun stone design (Piedra del Sol). The brooch also has a pendant loop so it can worn as a necklace. The brooch is stamped "925 TAXCO MEXICA ADO" & "3". This is the mark of Alberto Diaz Ocampo of Taxco. The "Eagle 3" mark on jewelry indicates the item was produced in Taxco, Mexico, between roughly 1948 and 1978. -Tested as Sterling Silver -Weight is approx 10.2 grams -Huitzilopochtli is the particular Mexican war god, a young and powerful sun-like deity that presides war and conquest. -Vintage from around the 1960s -Materials: Sterling Silver -Length: 2.25 inches -Width: 2.25 inches In very good pre-owned condition.
