Unusual Hallmark. Anyone know is it Hopi or Navajo and who is the maker? What is the stone?



Hi Folks; I was traveling from California, to Ohio and stopped in a tiny Colorado town east of Durango, Co. with a tiny, native shop and found this lovely pendant. I don’t know the hallmark and was hoping someone could tell me. The shop owner thought it was from Nevada but I was too dumb at the time to ask any questions. I would love to know the artist. Can anyone tell me what kind of turquoise this might be? Thank you.
