Amethyst, a captivating variety of quartz, holds a significant place in both the history of gemstones and the modern birthstone chart. Traditionally associated with the month of February, it has also been recognized as a June birthstone, reflecting the evolving nature of birthstone designations. This article will explore the geological origins, historical uses, gemological properties, and cultural significance of amethyst, drawing solely from available sources.
History and Lore
The history of amethyst stretches back to antiquity, with evidence of its use in ancient civilizations. In ancient Greece and Rome, amethyst was fashioned into vessels intended to hold beverages. A prevalent belief held that the stone could prevent intoxication, stemming from the Greek word “amethystos” meaning “non-intoxicated.” This association with preventing drunkenness contributed to its popularity among royalty and those prone to indulgence.
Historically, the Ural Mountains in Russia were a significant source of fine amethyst, with Catherine the Great acquiring a substantial collection. These stones, displaying deep purplish-red to purple-red hues, were specifically termed “Uralian” or “Siberian Amethyst,” designations that now serve as color grades rather than geographical indicators.
The assignment of specific gemstones to months evolved over time. Initially, each month had a single designated stone. However, in 1952, the Jewelry Industry Council of America added alexandrite as a June birthstone, alongside the traditional pearl. This illustrates the dynamic nature of birthstone lists, with modern additions supplementing the established traditional stones. Today, individuals often choose from both traditional and modern lists, selecting the stones that resonate with them most.
Geological Formation and Sources
Amethyst is a naturally occurring quartz, chemically composed of Silicon Dioxide (SiO2). It crystallizes within the hexagonal system and possesses a specific gravity of 2.66. Its hardness registers at 7 on the Mohs scale, indicating excellent scratch resistance and suitability for various jewelry applications. Refractive indexes range from 1.544 to 1.553, and it can exhibit strong dichroism in certain colored varieties.
Currently, Brazil is the primary source of amethyst used in the gem trade. However, historically, the Ural Mountains in Russia were renowned for producing high-quality specimens. Amethyst can be found in transparent, translucent, and opaque forms, often displaying color zonation where purplish zones alternate with white or grayish areas. This zonation can be particularly intense across all levels of transparency.
Gemological Properties
Amethyst typically presents as a transparent variety of quartz, exhibiting shades of purple. The saturation of this purple color can range from pale lilac to deep reddish-purple. Vividly colored stones are generally more highly valued than paler ones. The gem’s color is a key factor in determining its desirability and market value.
The gemological properties of amethyst contribute to its durability and appeal. Its hardness of 7 on the Mohs scale makes it resistant to scratching, suitable for everyday wear in rings, pendants, and earrings. The refractive index influences its brilliance and sparkle. Amethyst is uniaxial and positive, characteristics relevant to its optical properties.
Symbolism and Metaphysical Beliefs
Throughout history, amethyst has been imbued with symbolic meaning. The association with royalty, stemming from the color purple’s historical connection to the ruling class, elevated the stone’s status. Beyond its association with power, amethyst has also become linked to spirituality, mental clarity, and healing. These symbolic associations contribute to its enduring appeal and make it a meaningful gemstone for those seeking its perceived benefits.
Care and Cleaning
Due to its relatively high hardness of 7 on the Mohs scale, amethyst is a durable gemstone. However, like all jewelry, it benefits from proper care. Amethyst can be cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these may damage the stone or its setting. Regular cleaning will help maintain its brilliance and beauty.
June Birthstone Considerations
While traditionally the February birthstone, amethyst is also listed as a June birthstone alongside pearl and alexandrite. The inclusion of multiple birthstones for some months reflects a modern trend towards offering greater choice and personalization. Alexandrite was added to the June birthstone list in 1952, initially believed to be more abundant than pearls, though this is no longer the case. Alexandrite is a highly valued and rare gemstone, known for its color-changing properties. For those seeking a June birthstone, pearl, moonstone, and amethyst offer diverse options in terms of hue, price, and symbolism.

Conclusion
Amethyst stands as a testament to the enduring allure of gemstones. From its ancient origins as a preventative measure against intoxication to its modern status as a beloved birthstone, it has captivated cultures for centuries. Its vibrant purple hues, durable properties, and rich symbolism continue to make it a cherished gem for jewelry enthusiasts and collectors alike. The stone’s journey through history, coupled with its geological characteristics, solidifies its position as a significant and beautiful member of the quartz family.
