This large specimen consists of a polished slab with rough edges that contains a substantial amount of Native Silver. The Silver is easily visible on the polished faces, as its silvery-white color and metallic luster contrast quite well with the pink and gray host rock. Though actual crystal form has been destroyed by the cutting and polishing, a substantial portion of the visible metal shows definite dendritic formations that are indicative of crystal structure. Several other bits of silver that are scattered on the polished surface of the host rock do not show any form whatsoever. It is accompanied by several tiny bits of native gold, and some of the Silver looks as if it may have combined with the gold, as its color is slighty different than that of other areas. The host rock appears to be made of limestone, but it does not react with hydrochloric acid. Thus, I am thinking it consists primarily of quartzite and other silicic materials.
