This intensely-hued stone is a combination of copper minerals chrysocolla and red cuprite out of the Milpillas Mine in Sonora, Mexico and is often cut (into cabochons, etc.) to resemble a vibrant red sunset over a blue-green landscape. A large and excellent quality piece with both polished and rough surfaces.
