5.6" Polished Blue Lace Agate Section - South Africa

This is a beautiful polished section of blue lace agate collected from South Africa. The blue coloration of this specimen is truly wonderful and vibrant. These chalcedony veins are formed by hydrothermal deposition within large cracks in the Karoo Whitehill Formation. These cracks are caused by a fault that runs through the area.

Comes with an acrylic display stand.

Agate is a variety of microcrystalline quartz that displays translucence and in some cases banding. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, resulting in deposition of the silica along the walls of the rock. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers or rounded layers, depending on the surfaces available for deposition.
