Can anyone identify this dark blue turquoise?

Does anyone know what type of turquoise this is? I’ve rarely seen a dark blue turquoise before. I’m new to this site and love perusing thru all the posts!

Kingman, Ithaca Peak, Bisbee, Morenci, and Egyptian can sometimes be a darker blue.

It’s very hard to pinpoint a mine.

Agree with @Stracci. To add to the confusion, I have two very dark blue turquoise rings, which are Turquoise Mountain and probably Blue Diamond. However, Kingman is the most prolific American turquoise out there, so that’s why we default to that one a lot. Also this stone could be stabilized which would intensify the blue.
