Condor agate is a highly-prized gem and mineral specimen from the Mendoza Province of Argentina. Most specimens feature red, brown, and black banding, but colors can vary into blues, greens, and even white. A relatively new discovery, only known outside of Argentina since the early 1990s, Condor agate makes a wonderful addition to any mineral collection.

Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and in some cases banding. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, resulting in deposition of the silica along the walls of the rock. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers or rounded layers, depending on the surfaces available for deposition.
