Any ideas what mine this may be from?

Found this 7 lb chunk of vein turquoise in an old collection, and was hoping experienced members might recognize its provenance from the pictures and the following information.

- It was acquired sometime before  1990, and likely in the '70s or '80s.

- No signs of pyrite, nor quartz (except _maybe_ some quartz in one layer of matrix). Just light and dark brown matrix.

- No signs of any treatment, smells like earth.

- Light blue and teal veins, also one pale green vein. Surprisingly hard, glass and steel nail do not scratch it, or barely scratch some areas, quartz of course scratches it.
