2.9" Polished Banded Agate Nodule - Kuhn Quarry, Germany
This is a polished section of a banded agate nodule collected from Kuhn quarry in Rhineland-Palatinate, Germany. This specimen is from an old collection. The quarry has been closed for 15 years, making it more difficult to acquire this material. The "face" of this specimen has been polished while the opposite end has been left rough.
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.
