3.1" Polished Agate Nodule (Pair) - Zimbabwe

This is a beautiful, 3.1" wide banded agate nodule that has been cut in half and polished to a glossy-finish on both flat surfaces. This agate nodule was collected from Zimbabwe, Africa. Both haves are included and each half is accompanied by 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.
