agates
Agates
are among the most beautiful creations the world has
bestowed upon us. They
are semi-precious
gemstones that generally form within rock cavities, at low pressures
and
temperatures close to the surface of the earth, where they take on
distinctive
shapes and colours according to the local geology.
Agates
invariably outlast their surroundings,
with many rare and beautiful stones, their patterns and colours
seemingly
endless, laying just below the surface of known localities.
