Stunning, 6.8" Polished Malachite Egg - Congo
Typically a malachite egg of this size would be composed of multiple large malachite formations pieced together, however the vast majority of this egg is one solid piece. There are still small spots of gap fill. Comes with the pictured display stand.
Malachite results from the weathering of other copper ores and is very often found associated with other copper-based minerals such as Azurite and Chrysocolla. It can be found in copper deposits around the world, but the Democratic Republic Of The Congo is the primary source for polished malachite and mineral specimens.
Malachite has been prized since ancient times, first as a utilitarian copper ore, then as an ornamental stone. Due to it's value as a decorative stone, it's rarely mined as a copper ore anymore.
