7.1" Polished Banded Agate - Morocco
This is a gorgeous polished agate nodule half that was collected from Aouli, Morocco. One side of this specimen has been cut flat and polished to a glossy finish, while the other side and outer edge have been left rough. There are stick-like formations through the agate (stick agate), likely a result of aragonite formation. It comes with an acrylic display stand.
About Agate
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.
