Fiery, 7.9" Polished, Banded Agate Slab - Brazil

Fiery, Polished, Banded Agate Slab - Brazil #198076

This is a richly colored piece of banded agate that has been cut flat and polished on both sides. This specimen was collected in southern Brazil and features a variety of colors of agate including orange, yellow and red. This specimen is extremely beautiful and on the rarer side. A stunning piece if ever there was one. This slab may be heat treated to enhance the color, though we can't be sure.

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.
