Spiral Native American Navajo Turquoise & Sterling Silver Pin - store Vintage

There is just something so universal about spirals. It's one of the oldest, and I think most beautiful, symbols. You see spiral petroglyphs carved in to the store canyons, spirals on pottery, in weavings.... and in jewelry. This pin is just an artistic interpretation surrounding a blue turquoise. I believe this to be Navajo made, but it is a vintage piece and is unsigned.

Measurements:
about 1 3/8 in diameter (It's not a perfect circle)

The last two photos were taken near the Hopi Reservation.

Happy to answer any questions.
