3.7" Stunning Malachite Stalactite - Congo
This is an incredible, sparkling malachite stalactite collected from the Congo Mine in the Katanga (Shaba) Province of Congo. The layering of this botryoidal malachite can be seen by looking where the malachite has broken off from its natural location.
Malachite is a basic copper carbonate with the chemical formula Cu2CO3(OH)2. This mineral is known for its intense green color, along with the wide variety of formations and patterns that it's found in. Malachite can grow in botryoidal masses, stalactitic, and reniform formations, typically as a tight cluster of fanning fibrous needles that make up a seemingly solid mass. As layers continue to stack during formation, a banded pattern can sometimes begin to take shape, which explains the rings in all shades of green that are seen on most polished malachite specimens.
