This thumbnail specimen consists of a mass of native Silver that is partially enveloped by its calcite matrix rock. The Silver does not appear to have any crystalline form and seems to be free from any major human-induced damage. Its color ranges from a moderately dark to a bright silvery-gray and its luster ranges from a dull to a bright metallic. Given the intense difference in color and luster of some of the Silver in this specimen, I am thinking that some of it might be native Arsenic instead of Silver, but I really cannot be certain.
