5.5" Vibrant Polished Apache Agate - Mexico

This is a gorgeous 5.5" wide polished half of an Apache Agate nodule that features vibrant bands of blue and red coloration. It was collected from a remote location near Chihuahua, Mexico and has been cut flat on one side and polished. The quality of the polish is good to very good. The red bands seemingly flow together, a common characteristic of agates from this location.

It comes with an acrylic display stand.

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 rocks and/or fossils, depositing the silica along the walls of the rock. This process can result in banding patterns, as the compositions and impurities of these depositing fluids change over time. These banding patterns can either form as flat layers, creating linear patterns known as waterline agate, or as rounded layers, forming more common ring-like patterns. These patterns depend on the surfaces available for deposition.
