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.
