Amethyst
This beautiful purple stone is also a member of the large
quartz group. It contains traces of iron, and these iron
atoms became altered by exposure to natural radiation in
such a way that they produce a purple color
(otherwise, iron will create a green or
brown color).
In Brazil, it is not uncommon to find meter-long rock
cavities lined with amethyst crystals. There is also a
famous 400 meter-long amethyst gorge in the Austrian
town of Maissau — which inspired the locals to choose
purple as their “town color.”
