3.7" Polished Malachite - Congo
This is a beautiful, hand-polished piece of high grade botryoidal malachite mined in the Congo. The lapidary work is very nice, and allows for the great, natural, botryoidal patterns in the mineral to be seen. It makes for a very aesthetic display piece.
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.
