This vintage sterling silver, tufa cast bracelet has a natural Morenci or Lone Mountain turquoise set in the center (according to our resident turquoise expert).  It was definitely made for a small wrist.  It is stamped EA on the back and we think it might have been made by Navajo jeweler, Evelyn Abeita, in the 1960s or 1970s.  It has been very lightly polished to maintain the patina that comes with age.
