Most of this specimen's mass appears to be made up of native Silver. This Silver has no definite crystal form, so therefore damage cannot be accurately assessed. There are a few aspects of this piece that confuse me, though. The Silver can be easily seen as patches of a bright, silvery-white material with a bright metallic luster amidst the dull gray and white of the surrounding matrix rock. There are also some darker formations protruding from the matrix whose form are indicative of the metal. However, one entire side of the flat piece is covered with a material that I don't believe is native Silver, though it also shows the bright color and luster in areas. It also shows parallel striations on the metal that run the width of the specimen, and one particular formation that reminds me very much of some of the native bismuth specimens that we have had for sale. I may well be wrong, but this formation just makes me think about bismuth! The matrix is white and slightly chalky in areas, and I believe that it is calcareous in composition.
