Chalcedony is typically not considered a high-end collector mineral specimen, but sometimes Chalcedony, as well as Agate, certainly qualifies nobly: as with this large, striking specimen from Texas! This botryoidal, taupe-colored Chalcedony is lustrous and translucent consisting of nubs and short, rounded fingers of varying height that make for a very pleasing display piece. The display surface is in perfect condition with only minor contacting around the periphery as expected. The Needle Peak occurrence, more correctly named Sierra Aguja, is located near Terlingua, Texas and has produced some fine Chalcedony specimens such as this handsome cabinet piece. It is said that many were found in the 1930s-1950s here, and I assume this is such an example. Certainly, they are not contemporary.
