4.2" Beautiful Malachite Stalactite Cluster - Congo
This is an incredible malachite stalactite cluster, collected in the Congo. The layering of this botryoidal malachite can be seen by looking where the malachite has been broken off from its natural location. The base is relatively flat, allowing for natural aesthetic presentation. However, the specimen is accompanied by an acrylic display stand to assist with preferred presentation.
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.
