Introduction to Amethyst

By Jessica Wettig Hendrix

More than just purple quartz, amethyst has been around human culture for at least 2,000 years and ranks high on the list as everyone's all-time favorite crystal. Throughout time it has been coveted for its luscious purple color, healing powers, and its beauty.

The History of Amethyst

Amethyst has long been associated with the month of February, which is the month that the Romans dedicated to Neptune, the water god. Today it is February’s birthstone. It is also the stone of St. Valentine, faithful love, and stands for ecclesiastical dignity as the Bishop’s Stone.

Historically, it is believed to prevent drunkenness and overindulgence. Ancient Greeks and Romans studded their goblets with Amethyst, with the belief it would prevent intoxication. (Pretty sure it doesn't prevent you from becoming drunk... )

The Physical Elements of Amethyst

Amethyst, or purple quartz, is SiO2, or Silicon dioxide. It grows protruding clusters of pyramids off its matrix base. These "pyramids" can get quite large. You can also find it as tall prismatic crystals, short stubby crystals or in drusy aggregates. Amethyst also forms the internal lining of geodes, some of which can be over 10 feet tall and weigh several tons.

Its purple coloring is usually caused by impurities in clear quartz of iron or manganese compounds. As the amethyst quartz grows, it incorporates trace amounts of iron. Once crystals form, gamma rays naturally emitted by radioactive materials within the host rock, irradiate the iron and produce the purple color. Traces of other minerals and conditions will cause the color to vary from pale red-violet to deep violet, clear to almost opaque.

It ranks 7 on the Mohs Hardness scale, making it durable enough for rings, pendants, and other everyday jewelry. Since amethyst is common all over the world it is an affordable option for jewelry.

Metaphysical Properties of Amethyst

Amethyst is a master healing stone. It also offers protection, purification and can help you release addictions. It is a good choice to help you guard against psychic attacks. It's known as a dream stone and has been said to help clear up insomnia. Put an amethyst under your pillow to bring about dreams. But be observant. If you are bothered by the vivid dreaming amethyst can invoke, move it further away from your pillow.

You can also use it to open your spiritual and psychic centers. Use it as a meditation aid when worn as a necklace to focus your energy. I'm pretty sure it won't prevent you from becoming intoxicated but might help you keep your commitment to sobriety! Amethyst carries the energy of passion, fire, creativity, spirituality, temperance, and sobriety. Spiritually, amethyst connects us to the Divine. It’s a calming stone and has even been known to control evil thoughts, and increase intelligence. It is also used to connect with and balance the crown chakra.

For travelers, the stone is used for protection from surprise attacks and treachery. Soldiers have used it to protect them from harm and pursue victory. Hunters have used it to aid in capturing wild beasts.

It is also considered a powerful psychic stone of protection against evil, witchcraft, and black magic. All in all, it’s a must-have stone for your collection.

This is a variety of bi-color quartz in which citrine and amethyst come in contact with one another in a single crystal. It is rarely found in nature with the only current commercial mine in Bolivia. It combines the metaphysical properties of citrine and amethyst.

Prasiolite or green amethyst
Prasiolite or "Green Amethyst

Prasiolite is a yellow-green to green variety of quartz that is produced by either one of the three processes below. Also called "Green Amethyst" it is actually prasiolite.

~ Heat-Treated Amethyst: Most prasiolite is produced by heating natural amethyst in a laboratory oven to about 500 degrees Celsius. This heating changes the amethyst's color from purple to green or yellowish-green. Much of the yellow to golden quartz sold as “citrine” is actually amethyst that has been modified by heating.

Irradiated Amethyst: A small amount of prasiolite is produced by irradiating natural amethyst. This produces prasiolite with a light green color. The green color is often unstable and can fade to colorless if the stone is exposed to temperatures over about 150 degrees Celsius. This is one reason why you should avoid exposing your amethyst to direct sunlight for an extended period of time, as it can change color or lighten.

Naturally Heated Amethyst: There are small amounts of amethyst is heated by natural processes. It is found where an amethyst-bearing rock unit has been heated by younger lava flows or nearby intrusions.

Heating is also used to lighten the color of extremely dark amethyst or eliminate a brown tint that can be seen in many natural materials. Heating will not change the metaphysical properties of the mineral. The new or different color frequencies will add to the metaphysical properties of the crystal.
