The first stone I'd like to explore is: Amethyst

AMETHYST-
Amethyst is a very common stone used in jewelry making. It comes in several lovely shades of purple, and is mined in several different countries. It's a beautiful and an affordable stone, which makes it appealing to both jewelry makers and jewelry buyers.
Metaphysically speaking, Amethyst is a very "mental" stone, both stimulating, and calming as needed by the wearer. It is especially good at protecting its wearer from negative energy, and has even been said to have a sobering effect, which makes it useful if you are trying to overcome any type of addiction.
Amethyst is also a very spiritual stone, connecting one to the more divine energies. In this vein, it also helps the wearer to remember and interpret their dreams, and to have more intense visualization. Placed under your pillow, it can aid with insomnia or nightmares.
