3.9" Polished Orca Agate Flame - Madagascar
This is orca agate (a.k.a. “Orca Stone”) from Madagascar which has been hand-polished into a "flame" shaped sculpture. This beautiful piece is 3.9" tall and has a mixture of blue and white agate. The base has been cut flat so it displays nicely on a flat surface without the need for a 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 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.
