This large specimen consists of a section of "float" copper that made up part of an outcropping underground. It has a somewhat flat form and is partially covered in the bright green coating of oxidized copper. There are a few spots where some of the native igneous matrix rock is still attached, but these are minor. Portions of the specimen's surface have been ground smooth and polished to show the copper's reddish color and metallic luster. Most of the specimen is in its natural form, though. It has been almost completely coated with a lacquer to prevent further oxidation and decay of the copper. The only part of the specimen that I am certain is not covered with lacquer is the one cut surface that can be used as a rather sturdy "base" for its display. I have placed felt pads on this surface to prevent damage of any surface on which it is placed.
