This stunning specimen consists of dreamy stalactite spires made of green malachite coated with blue chrysocolla. To imagine how it grew, you have to turn it upside down. A copper-rich solution dripped down from the top, lengthening and thickening the spires. Knobs grew as outside forces, such as air currents, caused uneven growth. This specimen was found in the ‘copper crescent’ area of the Democratic Republic of the Congo, but it reminds us of an underwater scene from Atlantis.
