BulletPoint2 : Chrysocolla is attractive blue-green that provides a unique color to the mineral world. Chrysocolla is perhaps more appropriately a mineraloid than a true mineral. Most of the time it is amorphous meaning that it does not have a coherent crystalline structure. However at higher temperatures it does demonstrate a distorted crystal structure that seems to be composed of Si4 O10 sheets. Chrysocolla forms in the oxidation zones of copper rich ore bodies. BulletPoint3 : 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.
