banded chrysocolla
Chrysocolla is one of the strangest mineral names.  The name seems as if it should
apply to a soda drink instead of a mineral.  Technically, most chrysocolla is not a
true mineral because it lacks crystalline structure.  Most chrysocolla is just silica gel
stained blue by copper compounds.  In the specimen shown below the chrysocolla
is closer to an agate: tough and banded.  Some of the green color is due to the
presence of malachite.
