Amethyst
Properties: The stone of spirituality and dream recall.
Used for contentment and meditation. Provides common sense and
flexibility in decisions. Strengthens and enhances psychic abilities,
imagery and mind quieting. Wear when sleeping or when awake to reduce
anger, impatience, and nightmares. Most effective on the Brow and Crown Chakra.
Amethyst contains the grounding color of red with the energy of blue,
which is expanding, spacious and flow of peace. Amethyst is the color
that you see in the sky as twilight transitions into night. Amethyst
takes you on this transition from the magic time of dusk to a conscious
shift into a different place. Crossing this threshold is the lesson of humility,
which Amethyst can teach us. This stone can show us how to let go and
trust; surrender so that you may see beyond the cycle that consumes your
attention; give it all up, so that you can receive more; and bow, that
you may become a part of the greater whole. Amethyst is considered a [b]Master Healing stone.

Folk Remedies:
This crystal is the most recommended stone for stress relief. Amethyst
has a direct link to the mind. It bolsters the production of the

detoxifying stone. Especially helps in sobriety, as well as alcohol,
food, sex and other addictions. It soothes the nervous system and
assists in the transmission of neural signals. Helps you feel less
scattered and more in control of your faculties. Memory skills and
motivation improve. Goals are clearer, more realistic, and easier to
achieve. However, you must use this stone cautiously with subjects who
have paranoid or schizoid tendencies. Can benefit people with insomnia
or troubled sleep. Ideal for those who meditate. Promotes selflessness.
Useful in dispelling rage, anger, fear, and anxiety, and is a good stone
for clarifying and remembering dreams. Helps relieve physical and

History: Amethyst belongs to the Quartz family
(SiO2 Fe), found in Brazil, Canada, Sri Lanka, and parts of East
Africa. Color varies from a deep violet to a pale lavender, almost to
the point of being clear. Known as the prize stone since the days of
ancient Egypt, Amethyst holds an honored place in the Crown Jewels of
England, frequently known as the "Rose de France", a popular jewelry
item during the Victorian age and worn by every Pope since the sixteenth
century.
