COPPER
DESCRIPTION
This is a photo of a small piece of native copper from Michigan. If you look closely at the copper you can see dark red, glossy, string-like structures. These are likely cuprite, which is an oxide of copper. The clear crystals (at the edges of the copper at two and nine o’clock) may be calcite, the green crystals (on the right edge of the copper) epidote, and the matrix (the gray-green “host” stone the copper is on) is basalt.
