Moon River turquoise is a distinctive natural stone primarily sourced from mines in the Hubei Province, China. It is highly valued for its striking contrast and range of colors, which span from light greens to deep, rich blues.

A key characteristic of Moon River turquoise is its prominent black or dark brown matrix which creates intricate spiderweb or splotchy patterns against the vivid blue background. This stark visual difference makes the blue in the stone "pop," giving the material a bold, designer look.
