Amethyst
This stone is very good for curing headaches, migraine and insomnia.
Improve the ability to aspire stress, lowers blood pressure and

Amethyst is the most precious and valuable stone belonging to the
quartz group of minerals, with exception to rare blue-green gem
silica. It is recognized as the official birthstone for the month of
July. Amethyst belongs to the macro crystalline branch of quartz and
owes its violet-purple color to iron and aluminum impurities. Without
such coloring agents, amethyst would simply be transparent, ordinary
colorless quartz. Like other varieties of macro crystalline quartz,
amethyst has transparent to translucent clarity and a vitreous
luster. Cryptocrystalline varieties almost always occur with
translucent to opaque clarity.
