Crazy lace agate, also known as Mexican Agate is a unique banded agate that comes from Chihuahua Mexico. It gets its name from complex, lacy patterns swirling through the stone. Colors can vary from creme to orange, to red colorations and are due to iron and aluminum inclusions in the 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 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.
