7.2" Colorful Sonora Sunset (Chrysocolla Cuprite) Section - Mexico

Sonora sunset (also known as Sonora sunrise) is the trade name for a blue, green, black, and red mineral formation collected from the Milpillas Mine in Sonora, Mexico, a copper ore mine. While this mine is known for its high quality azurite, chalcocite, chrysocolla, cuprite, malachite, and pyrite mineral specimens, it also produces this gorgeous material, which miners would come across occasionally during mining. It is a combination of blue-green chrysocolla, vibrant red cuprite, and streaks of black attributed to iron oxidation. The material is usually cut in a specific orientation, using the black to separate the blue-green and red, creating the appearance of a green landscape with a red sunset/sunrise sky.
