7.8" Polished Cathedral Agate Section - Mexico

This is an alluring, polished "cathedral agate" section that was collected from Chihuahua, Mexico. It features a vibrant mixture purple, orange and red coloration. One side has been cut flat and polished to a glossy finish, while the opposite side has been left rough. Calcite crystal encrusted cavities surround the agate formations throughout this specimen.

Comes with an acrylic display stand to assist with presentation.

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.
