Behold, the agates which can be considered prettiest and strangest of any
rocks. Basically, agates are made up of the films of quartz microcrystals
which each film/band represents each wet period/season similar to the tree
growth rings but in reversed way sometimes in an unexplainable manner.
The impurities such as iron oxide ("rust") provide a wide variety of colors
to the agates. The agates come in a wide variety of forms from amygdaloidals
(gas bubbles in lava) to "Lithophysae ("thundereggs").
