The amygadoloidal agates were formed by filling in the gas cavities within
the dark colored basalt and andesite lava rocks. Since the basalt rocks
tend to be good source of impurities acting like coloring agents, the agates
are well known for their great variety of colors and shapes that cannot
be rivaled by any other minerals as demonstrated by the fact that they
had been widely used in many lapidary arts for thousands of years.
