Turquoise (Arizona Quality)

Raw Blue Arizona Turquoise 
High grade quality
Turquoise is a hydrated phosphate mineral (copper/aluminum) famous for its opaque blue-to-green color, with a Mohs hardness of 5–6 and a porous nature requiring stabilization. It is a highly valued gem for its protective, communication-enhancing, and calming properties, often used in sterling silver settings and polished into cabs.
