This is a Congolese Malachite Sphere. D.R. Congo is known throughout the world for having the finest of these gems. The egg has a superior polish. Because of this, the fine layering and striations are intense and sharp. The swirls appear like weather patterns on a Jupiter-like planet. In between these areas are bands of the finest striations of malachite. The entire piece has the breathtaking green Congolese malachite is famous for, ranging from an nearly black green to the softest light emerald imaginable. I acquired this mineral directly from the Congolese folks who handle the mining and shaping of this exquisite egg. I include a small nylon ring for setting this on.
