Type of turquoise and does anyone know this makers mark?

Also picked up this inexpensive Zuni money clip. engraved on the back looks like Hustito Zuni N.M

Well I found a hallmark that looks a lot like the above on & Southwest Shops Hallmarks, T to Z but no one associated with it

I’m awful at identifying mines, but I’ve had similar turquoise that was identified for me as Morenci and Kingman. Any flecks of pyrite in the matrix?
