1.85" Polished Botswana Agate - Botswana

This is a beautiful 1.85" wide banded agate nodule, polished to a mirror finish on one side. These agate nodules are collected from the Bobonong District of Botswana, Africa. These agates feature gorgeous parallel banding in a variety of color hues including white, blue, grey, purple, pink and red.

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.
