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.
Cuprite is a copper oxide mineral.

After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
