Sterling Silver and brass two tone brooch with three intertwined circles. The piece is not marked but was likely made in Mexico.
Condition: Very good with light patina. Personal preferences vary greatly for the amount of patina on vintage jewelry, therefore I tend to sell jewelry "as found" and leave polishing up to the new owner.
Size: The brooch is 2 1/4" wide and 2" from top to bottom.
Hallmark: none, silver area tests as sterling.
