This turquoise is mined from the Sonora mines in Mexico. Like all other natural turquoise, its coloring is the result of the chemical reaction that occurs when copper is introduced to water. These stones have unique green pigmentation when compared to other turquoise sourced from the region, which tends to be a strong blue color. These mines are also famous for sourcing North-American Jasper, an elusive stone with unique coloring. The mines these stones are sourced from are primarily copper mines, and turquoise is a leftover mineral from these practices.
