Polished Dendritic Agate - Madagascar Descloizite which occurs when iron andThis Polished Dendritic Agate is a striking mineral specimen sourced from the rich, diverse geological deposits of Madagascar. As a semi translucent variety of chalcedony quartz, this material is defined by its complex, tree like or fern like inclusions trapped inside a clear to milky silica body. These delicate structures are formed by a process known as dendritic branching, which occurs when iron and manganese rich mineral fluids seep into micro
