Malachite is a copper carbonate hydroxide mineral, with the formula
Cu2CO3(OH)2. This green-colored mineral crystallizes in the monoclinic crystal
system, and most often forms botryoidal, fibrous, or stalagmitic masses, in
fractures and spaces, deep underground, where the water table and hydrothermal
fluids provide the means for chemical precipitation. Individual crystals are
rare but do occur as slender to acicular prisms. Pseudomorphs after more tabular
or blocky azurite crystals also occur. Typical malachite is laminated and
whether or not microbes intervene in its formation is unknown

I gotta ask, do you know what all that chemical composition stuff means? I
don't. I mean sometimes I can understand a little bit of it but not much. If
it's explained to me I can get it. Sort of.
