Cut and polished half agate geode from the world famous agate sites near Salto do Jacui in the state of Rio Grande do Sul in the very south of Brazil. Often the cut agates are of a completely uniform gray colour, nevertheless there are various microporous concentric layers. These can be colored using different staining methods and colors. Various techniques for coloring agates were developed as early as the Middle Ages and are still used today. The trick is to find color pigments whose molecular chains are small enough to penetrate the microscopic pores.
