Copper in the ArtsFact 2 of 9
While copper is known for its rich red-gold hue, it doesn't often appear that way in nature. Instead, it can be found masquerading in shades of blue, green, red and turquoise. Thousands of years ago, the Egyptians learned that certain minerals contained valuable deposits of copper. These minerals include malachite (green), azurite (blue), cuprite (red) and turquoise (blue-green).
