Copper is a ductile metal with an excellent thermal and electrical conductivity. Pure copper is a fairly soft metal and has a pinkish or peachy color. It is an essential trace nutrient to all high plant and animal life. In animals, including humans, it is found primarily in the bloodstream, as a co-factor in various enzymes and in copper-based pigments.
These nuggets come from the so-called "Copper Country" of Michigan, where copper is found in an unusually pure state. Nuggets such as these were unearthed many thousands of years ago by glacial action. These naturally formed pieces have been cleaned of excess rock and other minerals, polished and coated to prevent discoloration. These weighty little pieces of pure metal make great gifts for kids, or a nice addition to a rock collection!
