Your guide to turquoise, geology, provenance, and the stories behind the stones.
Deep in the high desert of Northern Nevada, the earth holds a quiet secret — turquoise unlike anything found elsewhere on the planet. Not the familiar sky‑blue of postcard jewelry, but a vivid, iron‑born green and soft mint to lime skin green spectrum shaped by the same mineral trend that produced historic Orvil Jack turquoise.
Here you’ll find everything we know: geology, mining history, color science, identification guides, and the craft traditions that bring these stones to life.

FAQs
Is this turquoise for sale?
Yes. We offer both raw and cut material depending on availability. Please reach out through the contact us form.
Is the turquoise stabilized or treated?
No. Cortez Canyon Turquoise is gem quality and naturally hard and stable.
Where is this turquoise from?
Cortez Canyon Turquoise comes from extensions of the original veins Orvil Jack mined and first brought forward from Nevada’s desert.
Why is this turquoise green and not turquoise blue?
Turquoise coloration at Cortez Canyon results from hydrothermal fluids introducing a phosphate mixture of copper (blue), iron (green), and traces of zinc (lime) into a limestone-hosted fracture system. Precipitation of secondary phosphate minerals under variable metal ratios and host-rock interaction produced the observed mint-to-turquoise spectrum and localized color zoning.
Does it come with provenance or mine attribution?
High-value pieces include a provenance certificate.
