Amethyst holds a distinguished place in the annals of gemstone history. Its journey from ancient protective talisman to a modern symbol of sincerity and spiritual awareness is a testament to its enduring appeal. While some alternative birthstone lists may suggest other gems for February, such as zircon or pearl, amethyst remains the most historically and culturally significant choice for this date. Its calming color, associated with peace and tranquility, was a key factor in its designation as the February birthstone in 1912 by the American National Retail Jewelers Association, now known as Jewelers of America. This article will delve into the multifaceted nature of amethyst, examining its properties, lore, and the reasons behind its lasting popularity.
History and Lore
The history of amethyst is as rich and deep as its most prized violet colors. The gemstone's name provides the first clue to its ancient significance. In Greek mythology, it was believed that the gem could protect its wearer from the effects of intoxication. This belief led to the use of amethyst in drinking vessels, such as goblets and wine cups, with the hope that it would ward off drunkenness and promote sobriety. The ancient Greeks and Romans held this belief strongly, incorporating the stone into their daily lives and jewelry, associating it with clarity of thought and a clear mind.
As centuries passed, the symbolism of amethyst evolved. During the Middle Ages in Europe, the gemstone became a powerful symbol of piety and royalty. Its deep purple color, reminiscent of the robes worn by high-ranking clergy and monarchs, made it a favorite among the ecclesiastical and noble classes. It was frequently used in ecclesiastical vestments and royal regalia, signifying power, dignity, and a connection to the divine. This association with piety continued into the 19th century, where amethyst was also incorporated into mourning jewelry, its tranquil color offering a sense of peace and calm during times of grief.
The transition of amethyst to a modern birthstone is a relatively recent development. In 1912, the American National Retail Jewelers Association standardized a list of birthstones for each month, officially naming amethyst as the birthstone for February. This decision was influenced by the gem's long-standing cultural history and its perceived calming properties. The deep, calming color of amethyst was thought to bring peace and tranquility, making it a fitting symbol for the winter month of February. This official designation cemented amethyst's status as the primary birthstone for February, a role it continues to hold today.
Geological Formation and Sources
Amethyst is a variety of quartz, one of the most common minerals in the Earth's crust. Its chemical composition is silicon dioxide (SiO₂), the same as other quartz varieties like citrine and rose quartz. The distinctive purple color of amethyst is the result of trace amounts of iron impurities within the quartz crystal lattice, combined with natural irradiation. This process of color formation is a fascinating geological phenomenon that occurs under specific conditions of temperature, pressure, and chemical environment.
Amethyst forms in geodes and hollow cavities within volcanic and sedimentary rocks. These geodes can be found in various geological settings, often in areas with a history of volcanic activity. Over millions of years, silica-rich fluids seep into these cavities and slowly crystallize, layer by layer, to form the hexagonal crystals characteristic of quartz. The presence of iron and the subsequent exposure to natural radiation from the surrounding rock give the crystals their purple hue. The intensity of the color can vary significantly, with the most valued amethyst exhibiting a rich, even violet color with flashes of red and blue.
While amethyst can be found in many parts of the world, certain locations are renowned for producing high-quality specimens. Historically, some of the finest amethyst came from Russia, particularly from the Ural Mountains. These deposits, known for their deep, Siberian violet colors, are now largely depleted. Today, the primary sources of amethyst include Brazil, which produces vast quantities of amethyst in a range of qualities, from light lavender to deep purple. Other significant sources include Zambia in Africa, known for its dark, saturated colors, and Uruguay, which produces amethyst with deep color and often includes distinctive bands of darker and lighter purple. Other countries such as South Korea, Sri Lanka, and the United States also have amethyst deposits, though they may not be as commercially significant as the major producers.
Gemological Properties
Understanding the physical and optical properties of amethyst is essential for its identification, valuation, and care. As a member of the quartz family, it shares many properties with its relatives but has distinct characteristics that define its unique beauty.
Color: The color of amethyst ranges from a pale, delicate lilac to a deep, royal purple. The most prized color is often described as "Siberian," a deep violet with flashes of red and blue. Color zoning, where the color is not evenly distributed, can occur in amethyst crystals. Heat treatment is a common and accepted industry practice to alter amethyst's color. When heated to temperatures between 400-500°C, amethyst can lose its purple hue entirely, transforming into a pale yellow or yellowish-brown variety known as citrine. With further heating, it can become colorless, which is sometimes sold as "white quartz." This treatment is widely accepted and is not considered deceptive.
Hardness and Durability: Amethyst has a hardness of 7 on the Mohs scale, making it relatively durable and suitable for everyday jewelry. It is resistant to scratching by most materials but can be damaged by harder substances like diamond, corundum (ruby, sapphire), or even steel. Its toughness is fair, but it can be prone to chipping if struck with sufficient force, particularly at its facets or in thin settings.
Crystal System and Clarity: Amethyst crystallizes in the trigonal crystal system. It is typically found as hexagonal prisms, often terminated by pyramidal faces. In terms of clarity, amethyst is often found with some inclusions. Common inclusions can be needles of rutile, mineral inclusions, or growth zones. However, high-quality amethyst for jewelry is typically eye-clean, meaning it has no inclusions visible to the naked eye.
Cut and Carat Weight: Amethyst is cut into a wide variety of shapes and styles, from traditional rounds and ovals to more elaborate designer cuts. Its good hardness and lack of cleavage (a tendency to break along flat planes) make it suitable for intricate faceting. Amethyst is relatively abundant, so large crystals are not uncommon. Consequently, amethyst can be found in large carat sizes without a dramatic increase in price per carat, making it an excellent choice for statement jewelry pieces.
Refractive Index and Specific Gravity: As a quartz variety, amethyst has a refractive index ranging from 1.544 to 1.553 and a specific gravity of 2.65. These values are consistent with other types of quartz and are key identifiers for gemologists.

Symbolism and Metaphysical Beliefs
Amethyst is steeped in symbolism and is attributed with a wide array of metaphysical properties across different cultures and eras. Its association with calmness, spiritual awareness, and emotional stability has made it a cornerstone in crystal healing and modern metaphysical practices.
Cultural Symbolism: * Ancient Greece and Rome: As previously mentioned, the primary symbolism was protection against intoxication and the promotion of clarity of thought and a sober mind. * Medieval Europe: Amethyst was a symbol of piety, humility, and spiritual wisdom. It was believed to aid in connecting with the divine and was often worn by clergy and monks. * Modern Times: The gemstone has evolved to symbolize peace, courage, and inner strength. It is seen as a stone of sincerity, making it a particularly meaningful gift for those born on February 21st. Its calming energy is thought to help reduce stress, anxiety, and emotional turbulence.
Metaphysical Properties: In contemporary crystal healing, amethyst is considered a powerful protective stone. It is believed to create a shield against negative energy and psychic attacks, purifying the space and the aura of the user. Its connection to the mind is profound; it is said to enhance intuition, facilitate meditation, and promote a deeper spiritual understanding. Amethyst is also associated with the crown chakra, the energy center located at the top of the head that is responsible for spiritual connection and enlightenment. Using amethyst in meditation or wearing it as jewelry is thought to open and balance the crown chakra, leading to a state of higher consciousness and inner peace.
Furthermore, amethyst is sometimes used for physical healing, with beliefs that its calming properties may help alleviate pain and discomfort, particularly headaches and tension.

Care and Cleaning
Proper care is essential to maintain the beauty and integrity of amethyst jewelry. Given its physical properties, specific guidelines should be followed to avoid damage.
Due to its hardness of 7 on the Mohs scale, amethyst is durable enough for most jewelry types, including rings, pendants, earrings, and bracelets. However, it is not as hard as some other gemstones like sapphire or diamond, so it can be scratched by them. It is advisable to store amethyst jewelry separately from other pieces to prevent scratching.
Cleaning: Amethyst can be safely cleaned using warm water, a mild soap, and a soft brush. Ultrasonic cleaners are generally safe for untreated amethyst, but caution is advised for stones that may have been fracture-filled or have significant inclusions. Steam cleaning is not recommended, as the high heat and pressure can potentially damage the stone, especially if it has any internal fractures. After cleaning, rinse the jewelry thoroughly to remove any soap residue and dry it with a soft, lint-free cloth.
Heat Sensitivity: One of the most critical aspects of amethyst care is its sensitivity to heat. As mentioned, heating amethyst can permanently alter its color. Therefore, amethyst jewelry should never be exposed to high temperatures, such as those found in a jeweler's torch or a soldering station. It should also be kept away from prolonged exposure to direct sunlight, as some lower-quality amethyst may experience fading over time. When not in use, store amethyst jewelry in a dark, cool place to preserve its vibrant color.
