"Agates have fascinated man for thousands of years and are now one of the worlds most popular gemstones. Perhaps part of this fascination lies in the fact that no two agate nodules are ever exactly alike. The range of their colours, patterns and shape are almost endless and yet all have thought to have been formed by the one natural process. This variety is true of no other gemstone however rare or exclusive it is."
-- from "Scottish Agates" by Nick Crawford and David Anderson
