Amethyst Geodes Division
Geodes (Greek
geoides, "earthlike") are geological
rock formations which occur in
sedimentary and certain volcanic
rocks. Geodes are essentially rock cavities or vugs with internal crystal
formations or concentric banding. The exterior of the most common geodes is
generally
limestone or a related rock, while the interior contains quartz crystals
and/or
chalcedony and other mineral deposits. Other geodes are completely filled with crystal, being
solid all the way through. These types of geodes are called
nodules.
The size of the crystals, including their form and shade of color,
vary—making each geode unique.
Minerals found in geodes include
quartz and chalcedony, calcite, selenite, marcasite and pyrite, barite,
sphalerite, strontianite, pyrolusite, goethite and kaohnite.
There is no easy way of telling what the inside of a geode holds until it
is cut open or broken apart, however, geodes from any one locality usually have
a more restricted variety of interior mineralization.
Amethyst
is a violet variety of
quartz often
used as an
ornamental stone
in
jewelry. The
name comes from the
Ancient Greek
a- ("not") and methustos ("intoxicated"), a reference to the
belief that the stone protected its owner from
drunkenness;
the
ancient Greeks
and
Romans wore
amethyst and made drinking vessels of it in the belief that it would prevent
intoxication.
