Agate can be many different colours, and because its banding is so variable, different types
of it have been given many different descriptive names. It is often used to make quite large
decorative items. Some names include moss agate and picture agate. Many types of organic
material have been fossilized by agate, where the organic material has been replaced slowly
over a long period of time, so that the original structure of the original item is retained.
Fossilized or petrified wood is an attractive form of agate. It is is frequently found in the
form of rounded nodules or geodes. When split or sliced, these show their banding to good,
sometimes startling effect. In some geodes there is a central cavity, in other the centre is
hollow. This provides an important clue to the formation of such geodes. The Indians (sorry,
Native Americans) of the western American states called agate nodules "thunder eggs", a
wonderfully romantic and descriptive name.
