Turquoise source identification

I own a vintage double squash blossom necklace that I think uses Kingman mine stones, but I’m not sure either… they could be from the Royston or Cinderella mine as well. I purchased the necklace from an Apache who repaired the piece.

I appreciate any information you may provide.

Stay healthy and be safe.

This looks like Old Man Turquoise from the Turquoise Mountain Mine that was located near Kingman but closed down in the 80’s.

I’m not familiar with the Old Man mine, but I have cut a LOT of Turquoise, and this looks very much like classic Royston to me.

Thank you! I’ll do some looking at old Royston turquoise.

Sorry Mitzi I didn’t see your response until just now. Thank you! I’ll check out Old Man Turquoise too.
