For those born on February 21, the birthstone is Amethyst, a gemstone renowned for its captivating purple hue and rich historical and symbolic associations. As the official birthstone of the entire month of February, Amethyst holds a special place in gemological lore, particularly for those born on this specific date. This article explores Amethyst's geological properties, its historical and cultural significance, and its role in both spiritual and practical contexts.
History and Lore
Amethyst has been treasured by civilizations throughout history for its beauty and purported metaphysical qualities. The name Amethyst derives from the Greek word amethystos, meaning "not drunken," a reference to the belief that the gemstone could protect against the effects of intoxication. Ancient Greeks and Romans often used amethyst in drinking vessels and jewelry, believing it to promote sobriety and clarity of thought.
In medieval Europe, Amethyst was associated with piety and was frequently worn by clergy. During the Renaissance and Baroque periods, it became a symbol of nobility and was used in royal regalia and ecclesiastical vestments. Its use in religious contexts continued into the 19th century, where it was also incorporated into mourning jewelry due to its association with tranquility and peace.
In more recent times, Amethyst has become a popular birthstone and is often given as a meaningful gift to those born in February. It is also traditionally associated with the sixth wedding anniversary, making it a significant gemstone in both personal and romantic contexts.
Geological Formation and Sources
Amethyst is a colored variety of quartz, scientifically classified as dichroic quartz due to its ability to display two different colors under certain lighting conditions. Its characteristic purple coloration is due to trace amounts of iron impurities within its crystal lattice, combined with natural irradiation. This process alters the crystal structure of quartz, producing the vibrant violet tones for which Amethyst is known.
Amethyst is formed in geodes and crystalline rock formations, often found in volcanic environments. It is most commonly found in hydrothermal veins, where mineral-rich water cools and deposits quartz over time. These conditions allow for the slow growth of large, well-formed crystals.
Key Mining Locations
Amethyst is mined in several countries around the world, with the largest and most notable sources including:
- Brazil – The most prolific source of high-quality Amethyst, particularly in the states of Rio Grande do Sul, Minas Gerais, and Bahia. Brazilian Amethyst is known for its deep purple color and clarity.
- Ukraine and Russia – Historically important sources, especially for the famous "Siberian Amethyst."
- Madagascar – Produces a range of Amethyst hues, from pale lavender to deep violet.
- Zambia – Known for its rich purple Amethyst, often found in large geodes.
- Uruguay and Argentina – South American countries that also produce notable Amethyst deposits.
The availability of Amethyst from these regions ensures a steady supply for the global market, making it one of the more accessible gemstones among the birthstones.
Gemological Properties
Amethyst is a versatile gemstone, valued not only for its color but also for its durability and optical properties. Below is a detailed breakdown of its key gemological characteristics:
Color
- Primary Color: Purple, ranging from pale lavender to deep violet.
- Secondary Colors: Occasionally shows hints of red or blue due to dichroism.
Hardness
- Mohs Hardness: 7 (on a scale of 1 to 10).
- This moderate hardness makes it suitable for most types of jewelry, although it is softer than diamonds, sapphires, and rubies.
Clarity
- Amethyst is typically eye-clean, meaning it appears clear to the naked eye, though it may contain minor inclusions visible under magnification.
- Some inclusions are considered natural and can enhance the stone's uniqueness.
Cut
- Amethyst is often cut into brilliant cuts (like emerald or round) to maximize its fire and sparkle.
- Cabochon cuts are also common, especially for larger, raw Amethyst specimens.
Carat
- Amethyst can be found in a wide range of sizes, from small accent stones to large, statement pieces.
- Larger Amethyst crystals are relatively common, which is unusual for gemstones of its quality.
Chemical Composition
- Chemical Formula: SiO₂ (Silicon Dioxide), the same as clear quartz.
- The purple color is due to iron impurities (Fe³⁺ ions) and natural irradiation.
Refractive Index
- Refractive Index: 1.54–1.55
- Amethyst has a low dispersion, meaning it does not display the same "fire" as diamonds or zircons.
Specific Gravity
- Specific Gravity: 2.65
- This is typical for quartz and helps distinguish it from imitations.
Treatments
- Amethyst is often heat-treated to enhance or stabilize its color. Heat can lighten the color or convert it to a yellow or green hue, known as Citrine or Green Amethyst.
- These treatments are widely accepted in the gemstone industry and are not considered deceptive.
Alternatives
- For February 21, some sources also list Zircon and Pearl as alternative birthstones. However, Amethyst remains the most historically and culturally significant choice.
Symbolism and Metaphysical Beliefs
Amethyst has long been associated with calmness, spiritual awareness, and emotional stability. It is considered a stone of sincerity, making it a meaningful gemstone for those born on February 21.
Cultural and Historical Symbolism
- Ancient Greece and Rome: Believed to ward off drunkenness and promote clarity of thought.
- Medieval Europe: Associated with piety and often worn by clergy.
- Modern Times: Seen as a symbol of peace, courage, and inner strength.
Metaphysical Properties
- Emotional Balance: Amethyst is believed to help reduce stress, anxiety, and emotional turbulence. It is particularly recommended for those with highly sensitive or intuitive personalities.

Zodiac and Astrology
- Zodiac Sign: Amethyst is the birthstone for both Aquarius and Pisces, depending on the exact date of birth. For those born between January 21 and February 18 (Aquarius) and February 22 and March 20 (Pisces), Amethyst is believed to enhance their natural traits and provide spiritual support.
- Astrological Benefits: For Pisces, in particular, Amethyst is thought to help calm the mind and reduce anxiety. It is also believed to help improve brain function and memory, making it an ideal stone for those in need of mental clarity.
Care and Cleaning
Due to its Mohs hardness of 7, Amethyst is relatively durable but still requires proper care to maintain its beauty and longevity.
Best Practices for Cleaning
- Avoid Ultrasonic Cleaners: These can damage Amethyst, especially if it has inclusions or has been heat-treated.
- Warm, Soapy Water: The safest way to clean Amethyst is with a mild detergent and a soft cloth. Gently wipe the stone and rinse with lukewarm water.
- Avoid Steam Cleaning: This method can cause thermal shock, especially in heat-treated Amethyst.
Storing Amethyst
- Avoid Prolonged Sunlight Exposure: Amethyst can fade over time if exposed to strong sunlight for extended periods.
- Store Separately: To prevent scratches, store Amethyst jewelry in a soft cloth or a padded jewelry box away from harder gemstones like diamonds or sapphires.
Wearing Amethyst
- Amethyst is suitable for daily wear, but it is best to avoid wearing it during activities that could cause physical impact or exposure to harsh chemicals.
