This impressive specimen consists of a large plate of native "float" Copper. It shows areas on one of its green, oxidized surfaces that have been ground smooth, polished, and then coated with a clear lacquer to prevent further oxidation. There also appear to be some very small areas that contain thin layers of noncrystalline cuprite, judging by their deep, almost rust-red color. The other side of the flat specimen is completey untouched, showing a heavily pitted surface that is stained green with oxidation. Such a piece would look magnificent on the mantle of a stone or slate fireplace!
