Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, iron impurities (in some cases in conjunction with transition element impurities), and the presence of trace elements, which result in complex crystal lattice substitutions. The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry.

History

Amethyst has been highly esteemed throughout the ages for its stunning beauty and legendary powers to stimulate, and soothe, the mind and emotions. It is a semi-precious stone in today’s classifications, but to the ancients, it was a “Gem of Fire," a Precious Stone worth, at times in history, as much as a Diamond. It has always been associated with February, the month the Romans dedicated to Neptune, their water-god, and is the traditional birthstone of that month. It is the stone of Saint Valentine and faithful love and signifies ecclesiastical dignity as the Bishop’s Stone. It carries the energy of fire and passion, creativity and spirituality; yet bears the logic of temperance and sobriety.

Formation and Characteristics

The most prized amethyst are those with a deep purple color with hues of red. Amethyst forms in silica-rich liquids deposited in gas cavities (geodes) in lava. It can form as crystalline crusts, massive aggregates, or as quartz veins. Its purple coloration is due to the presence of iron and aluminum impurities. The color of amethyst has been known to fade over time due to prolonged exposure to sunlight.

Varieties and Locations

Amethyst is found in a variety of locations around the world. Its primary sources include Brazil, Uruguay, South Korea, Russia, and Zambia. Brazilian amethyst tends to be larger, while African amethyst is known for its deeper color.

Uses

Beyond its use as a gemstone in jewelry, amethyst has been used for intaglio engraved gems and in the carving of ornamental objects. Historically, the stone was believed to protect against drunkenness – the Greek word amethystos means "not intoxicated", from a-``, "not" + methystos, "intoxicated". Amethysts are also thought to have healing properties, helping to purify the mind and clear it of negative thoughts. This includes the alleviation of sadness and grief, and providing a connection to the divine.

Cultural and Mythological Significance

In mythology and crystal healing, amethyst is associated with many powers, including the ability to calm or stimulate the mind, enhance intuition, aid in meditation and visualization, and absorb negative energy. It has been worn as protection from self-deception, as well as a protection against witchcraft. The amethyst has been used to symbolize deep love, happiness, humility, sincerity, and wealth.
