Vintage Sterling Silver Pyrite or Hematite Ring Old Pawn Native American style 8

Beautiful vintage oval sterling silver ring. It reminds me very much of old pawn Native American pieces. Looks to be signed “DOTT” but I’m not sure. I cannot confirm who made this, or where it was made. It features an oval dark opaque silver mirror-like stone. This may be pyrite or hematite ? As you can see there is a tiny chip on one end of the stone. Know this before purchasing. Very southwestern vibe, but with a wiccan witchy flare. Marked size 8 , but it measures very slightly smaller. Approx 1” overall height. Turquoise ring is not included in this listing. I can polish the sterling silver upon request ☺️ Some people prefer the tarnished look, so I’ve left it unpolished for now.
