9" Single-Side Polished Banded Agate - Madagascar

This is an agate specimen from Madagascar which has been hand-polished from its original rough/natural state. This beautiful piece is 9" wide and has stunning hues of blue and white agate. One side is polished to a mirror-finish, while what could be considered the back of the specimen, has been left rough.

Comes with a 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.
