This natural green turquoise specimen carries the distinctive character of Cortez Canyon — vivid lime-to-mint green color formed in limestone, with blue spotting that creates a one-of-a-kind pattern no two pieces share.
Unlike most turquoise, which gets its color from copper, this material owes its vivid green to zinc — a rare geological condition found in only a handful of Nevada formations. The limestone host rock gives Cortez Canyon stones their characteristic color depth and stability. What you see today is what this stone looks like in 20 years.
Weight: 6.12g
Form: Natural rough / specimen
Origin: Cortez Canyon, Lander County, Nevada
Treatment: None — 100% natural, never stabilized, never dyed
Perfect for: Collectors seeking unusual Nevada turquoise, lapidary artists working with natural rough, or anyone drawn to stones with genuine geological character.
The blue spotting on this piece is a natural color variation caused by localized copper concentration within the zinc-dominant matrix — making it a particularly unusual specimen even within this already rare material.
