7.5" Polished, Crazy Lace Agate Slab - Western Australia

This is a cut and polished, yellow and red "crazy lace" agate slab, collected from Marillana Station north of Newman, in the Pilbara region of Western Australia. The specimen has been polished to a mirror like finish and 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.
