Theophrastus, the successor to Aristotle in ancient Greece was the first to use the Greek word Crysos " meaning gold" and kolla " meaning glue" as he discovered the mineral could be used to solder gold. Chrysocolla is of secondary origin and is found where copper ore oxidizes. It commonly forms in botryoidal masses and on occasion, due to its similarity in appearance, can be confused with Turquoise.
Malachite is a secondary mineral of copper ore that is light green to deep dark blue green in color. The name Malachite is derived from ancient Greece, meaning "Mallow green stone", in reference to the leafy foliage found on the Mallow plant. Typically, Malachite is found as crystalline aggregates, or crusts, and the mineral is commonly found in banded form, similarly to agate. Sometimes it is found in botryoidal (bulbous) cluster formations. When a Malachite mineral specimen forms in this shape, it is referred to as a Malachite Brain or broccoli due to the similarity in appearance. Malachite is also found as a pseudomorph, with one of the other minerals commonly being azurite.
