4.6" Polished Banded "Island Agate" Section - South Pacific

This is a beautiful cut and polished agate nodule half that was collected from an unidentified island in the South Pacific Ocean. The agate is banded, has orange to yellow coloration with white bands. The mystery island that these agates are collected from is being kept secret, though its believed to be from one of the many islands near Indonesia.

It comes with 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.
