Vintage Native American Navajo Womans ring. Green Turquoise Stone and Abalone Shell. Size 6.5 No Hallmark or Stamping. This reminds me of a 60's style with big stones and big silver leaf's. I bought this jewelry 20 years ago from Navajo Reservation in Gallup. This item has never been worn. (I have a ring sizer and can make 1 size bigger if needed.
