5.6" Polished Smugglers Moss Agate Section - Mexico

This is a 5.9" wide polished section of smugglers moss agate that was collected from Mexico. It has been cut flat and polished to a glossy finish on one side, while the edges and back have been left in their rough state.

Moss agate is a variety of chalcedony, frequently containing colorful (green, red, brown, etc..) mineral inclusions or brown to black dendrites of iron or manganese oxides.

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.
