Amethyst, a captivating variety of quartz, holds a prominent place in the world of gemstones, most notably as the birthstone for February. Revered for its alluring purple hues, ranging from delicate lilac to deep violet, amethyst boasts a rich history intertwined with mythology, royalty, and spiritual beliefs. This article delves into the geological origins, historical significance, gemological properties, and enduring symbolism of this remarkable gem, drawing solely from available sources.
History and Lore
The story of amethyst stretches back to ancient times, with its origins deeply rooted in Greek mythology. The name itself, derived from the Greek word amethystos, meaning “not intoxicated,” reveals a fascinating early belief. Ancient Greeks believed that wearing amethyst could protect against drunkenness, leading to its use in crafting drinking vessels and personal adornments. This association stemmed from the gem’s wine-like color and its perceived ability to ward off the effects of alcohol.
The Romans, too, valued amethyst, with officials and priests wearing the stone to maintain clarity of thought and sobriety during important decision-making processes. Beyond its practical application, amethyst was considered a symbol of luxury and status, frequently incorporated into jewelry worn by the upper classes.
Throughout history, amethyst has maintained its appeal among royalty and religious figures. Catherine the Great of Russia amassed a significant collection of amethysts from the Ural Mountains, prized for their deep purplish-red to purple-red hues, now referred to as Uralian or Siberian Amethyst, terms that have become color grades. The stone was dedicated to St. Valentine and associated with Bacchus, the Greek god of wine, further cementing its multifaceted symbolism. During the Renaissance, amethyst was believed to possess the power to temper passionate emotions and overcome temptation.
Geological Formation and Sources
Amethyst is a transparent to translucent variety of quartz, with a chemical composition of Silicon Dioxide (SiO2). It crystallizes within the hexagonal system and registers a 7 on the Mohs hardness scale, indicating good durability. The gem’s color arises from irradiation, iron impurities, and the presence of trace elements within the quartz structure. Color zonation, where purplish zones alternate with white or grayish areas, is a common characteristic, and can be quite intense in various specimens.
Currently, Brazil is the primary source of amethyst used in the gem trade. However, historically, the Ural Mountains in Russia were renowned for producing fine amethysts. Other significant sources include Uruguay, India, Zambia, and South Africa, each region yielding amethysts with unique characteristics in terms of color, clarity, and crystal size.
Gemological Properties
Amethyst exhibits refractive indexes ranging from 1.544 to 1.553 and is uniaxial, positive. It may also display strong dichroism in certain colored varieties. The specific gravity of amethyst is 2.66.
The color of amethyst is its most defining characteristic. While typically purple, the shade can vary considerably, from pale lilac to deep, rich violet. The most desired hues historically were deep purplish-red to purple-red, as found in the Uralian and Siberian amethysts. Amethyst can be found in both natural crystal form and as manufactured stones created in a laboratory.
The following table summarizes key gemological properties:

| Chemical Formula | SiO2 |
| Crystal System | Hexagonal |
| Hardness (Mohs) | 7 |
| Specific Gravity | 2.66 |
| Refractive Index | 1.544-1.553 |
| Color | Violet/Purple |
Symbolism and Metaphysical Beliefs
Throughout history, amethyst has been imbued with a wealth of symbolic meaning. It represents intellect, temperance, and love. The stone’s association with preventing intoxication evolved into a broader belief in its ability to promote clear thinking and a calm demeanor.
In spiritual practices, amethyst is valued for its purported healing properties. Some sources suggest it can treat skin ailments and cure tumors, though these claims are not widely accepted in formal gemology. It has also been believed to protect against drunkenness, not just through preventing intoxication, but by encouraging moderation. Hildegard von Bingen, a German Benedictine abbess, writer, composer, philosopher, mystic, visionary, and medical writer, wrote that amethyst could treat skin ailments and cure tumors.
The stone’s connection to royalty and religious leaders further enhanced its symbolic weight, representing power, piety, and spiritual insight. For those born in February, amethyst is not merely a birthstone but a symbol of personal empowerment and inner strength.
Care and Cleaning
With a Mohs hardness of 7, amethyst is relatively durable and suitable for everyday wear. However, like all gemstones, it requires proper care to maintain its brilliance. Amethyst should be cleaned with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the stone. Prolonged exposure to sunlight can cause the color to fade over time, so it is best to store amethyst jewelry in a dark, cool place.
Conclusion
Amethyst stands as a testament to the enduring allure of gemstones. From its ancient origins steeped in mythology and religious belief to its modern status as a beloved birthstone and symbol of clarity and strength, amethyst continues to captivate and inspire. Its rich history, coupled with its beautiful purple hues and relatively accessible price point, ensures its continued popularity among gemstone enthusiasts and jewelry lovers alike. The stone’s multifaceted symbolism and perceived metaphysical properties further contribute to its enduring appeal, making it a truly remarkable gem with a legacy that spans millennia.
