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.
