Name: Named in antiquity (see Pliny the Elder, 79 CE) molochitus after the Greek μαλαχή, “mallows,” in allusion to the green color of the leaves. Known in the new spelling, malachites, at least by 1661.
Malachite is a green, very common secondary copper mineral with a widely variable habit. Typically it is found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well. Single crystals and clusters of distinguishable crystals are uncommon, but when found they are typically acicular to prismatic. It is also frequently found as a pseudomorph after Azurite crystals, which are generally more tabular in shape.

Malachite forms as copper or other copper minerals deteriorate in the ground, in the presence of carbonates.
No way! So cool! ❤❤❤
We got a lot of copper in Cyprus but I haven’t found a solid piece
Awe, it’s so cute!
Dayum, that color tho~
Been enjoying these shorts of really tasty minerals.
I still instantly think Sailor Moon, but malachite is definitely one I want to see irl someday
That’s really pretty!!
It’s the rainy season in Japan right now, so green minerals like this give me energy. I hope the rainy season opens soon…
