Kalukaluku Mine, Katanga Proirng, Congo
Another Kalukaluku malachite specimen, although this one feels heavier than most this size. That is because the malachite nearly filled the cavity in the host talc, leaving few voids. There is a bit of the talc remaining, as an off-white crust with a greasy feel. The malachite is easily seen to be a botryoidal crust, centimeters thick in places, with a radial pattern of intensely green transparent acicular crystals, often intergrown with black motramite crystals which have a different habit in some areas. The malachite in the cavity is generally darker than most, with only a little of the velvety luster so often seen in these specimens. However, there is one large spary of pure bright green malachite, almost like an isolated spray of moss leaves, and under a loupe these look like stiff, bright green ropes.
