This lovely specimen is loaded with swirls of light and dark greens that comes from it's natural botryoidal origin. Malachite often forms in botryoidal, or in fibrous and or in stalagmitic masses in underground spaces and weathered (or wearing down) copper is what gives the neat variations of the green colors that one will find in malachite. Plus this one has Chrysocolla with it and just like the Malachite it needs the copper to give it it's blue shades of color!
