This is one of those pieces that made me gasp when I saw it! The "whirling logs" insignia (often mistaken for a swastika) has traditionally been used by many cultures to represent the four winds. Native Americans used it regularly pre-Nazi Germany. In 1940, the Native American Council signed a treaty declaring that they would no longer use the symbol now recognized as negative. This piece came from an estate collection out of San Antonio, TX. It was in a safe deposit box, waiting to be found. Sterling Silver, with Turquoise stones. Measures 2.25" across, but can be squeezed to adjust.
