Rough Stone

Found this on my Uncle’s land in Northern Arizona : ) Do you think it’s Turquoise? Measures 4 x 2.5". TIA.

Maybe, or chrysocolla or both. I see some malachite and azurite in there.Tough to tell from the pictures. Cool looking specimen anyway. Sorry not very helpful just my opinion

Looks like chrysocolla and azurite. How hard are the turquoise colored areas?

Thanks @fernwood and @markyboy57. After looking around found the examples of what you suggested- looks like what you’re saying.

I was able to lightly mark the most densely colored area with a steel screwdriver whereas, the same scratch test proved the dark brown and red host rock were twice as soft and not as dense.

The 4 x 2.5" stone is pretty heavy with a total weight of 11.5 ounces/327 grams. Thanks again : )
