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.
It comes with an acrylic display stand.

About Agate
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.
