Amethyst is a variety of quartz, a mineral composed of silicon dioxide (SiO₂). Its distinctive purple coloration is attributed to the presence of iron impurities within the crystal lattice, often combined with natural irradiation. The color can range from delicate lilac to a deep, saturated reddish-purple, with the most prized shades exhibiting a rich, even tone without undesirable brown or gray overtones. As a member of the quartz family, amethyst possesses a Mohs hardness of 7, making it sufficiently durable for most types of jewelry, including rings, pendants, and earrings. Its relative affordability, especially in smaller sizes, has contributed to its widespread popularity, allowing it to be accessible to a broad audience while still holding a place of honor in fine jewelry collections.
The selection of amethyst as a February birthstone is not arbitrary. It is deeply connected to the zodiac signs of Aquarius (January 20 – February 18) and Pisces (February 19 – March 20). For Aquarians, the gem is said to boost creativity and innovation, while for Pisceans, it is believed to nurture empathy and emotional depth. This astrological linkage adds another layer of personal significance to the stone, making it a meaningful gift for those celebrating a birthday in February. The following sections will explore the multifaceted nature of amethyst, from its historical journey to its scientific characteristics, providing a thorough understanding of why this violet gem continues to enchant and inspire.
History and Lore
The history of amethyst is as deep and varied as its color palette. The term "amethyst" derives from the Greek word amethystos, which translates to "not intoxicated." This etymology is rooted in an ancient Greek belief that the stone could protect its wearer from drunkenness. According to legend, the god Bacchus, the Roman deity of wine, was angered by a mortal and vowed to have the first person he met devoured by tigers. A beautiful maiden named Amethyste, on her way to worship at the temple of Diana, was set upon by the beasts. Diana, to save her, transformed her into a pure white stone. When Bacchus saw this, he wept tears of wine over the stone, staining it purple and giving rise to the gem we know today. This myth cemented amethyst’s association with sobriety and clarity of mind, a symbolism that persisted for centuries.
Throughout history, amethyst has been a symbol of power, royalty, and spirituality. Its regal purple hue was once as prized as ruby and emerald, adorning the crowns, scepters, and jewelry of European monarchs and clergy. In the Christian church, amethyst was associated with the apostles and was used in the rings of bishops and cardinals, symbolizing piety, chastity, and spiritual connection. The stone’s connection to the color of royalty was not limited to Europe; in ancient China, amethyst was also highly valued and used in ornamental carvings and jewelry.
The journey of amethyst to becoming a modern birthstone is more recent and is part of a broader tradition of birthstone assignment. The concept of birthstones can be traced back to biblical times, specifically to the High Priest’s breastplate described in the Book of Exodus, which featured twelve stones representing the twelve tribes of Israel. Over time, these stones became associated with the zodiac signs and, later, the months of the year. The modern list of birthstones was largely standardized in the early 20th century by the American National Retail Jewelers Association (now Jewelers of America), with the GIA and the American Gem Society (AGS) playing key roles in maintaining these associations. While historical charts sometimes listed alternatives like pearl or onyx for February, amethyst’s beauty, durability, and symbolic appeal secured its position as the primary birthstone for the month. Sources note that these alternatives, such as pearl, were sometimes linked to February’s zodiac signs, but amethyst remains the dominant choice in contemporary practice.
Geological Formation and Sources
Amethyst is a variety of quartz that forms in geodes and cavities within volcanic rocks. Its formation requires a specific combination of conditions: silica-rich solutions, iron impurities, and natural radiation. As these solutions cool and crystallize, the iron atoms interact with the natural radiation present in the environment, creating the purple color centers within the quartz crystal lattice. The intensity of the color can vary based on the concentration of iron and the level of radiation exposure, with deeper purples often resulting from higher iron content and sustained irradiation.
While amethyst can be found in various locations around the world, certain regions are renowned for producing high-quality specimens. Historically, one of the most famous sources was the Ural Mountains in Russia, which produced the "Siberian" amethyst known for its deep, reddish-purple color. However, many of these mines are no longer active. Today, significant sources include Brazil, which is the largest producer of amethyst, particularly from the state of Rio Grande do Sul. Brazilian amethyst often occurs in large geodes and can range from light to medium purple. Other notable sources include Uruguay, which produces amethyst with a darker, more saturated hue, as well as Zambia, Namibia, and Madagascar. In the United States, amethyst is found in states like Arizona and North Carolina.
The market value of amethyst is influenced by several factors, including color, clarity, cut, and carat weight. As noted in the sources, darker tones of amethyst are often considered more valuable, provided the color is even and free from zoning. The gem’s clarity is also important; high-quality amethyst should be clear and free of visible inclusions that could diminish its brilliance. While large amethyst crystals are not uncommon, faceted stones over one carat that exhibit a deep, uniform purple color command higher prices. The availability of lab-grown amethyst, which provides consistent pale colors, offers an ethical and affordable alternative for consumers, though natural amethyst with its unique color variations remains highly sought after.
Gemological Properties
Understanding the gemological properties of amethyst is essential for appreciating its value and ensuring its proper care. As a variety of quartz, amethyst shares many properties with its family members, but its specific characteristics make it a unique and desirable gemstone.
Chemical Composition and Structure: Amethyst is a crystalline form of silicon dioxide (SiO₂). Its purple color is due to trace amounts of iron (Fe) incorporated into the crystal structure during formation, combined with natural irradiation. The crystal system is trigonal, and it typically forms as six-sided prisms terminated by pyramids. The presence of iron impurities is what distinguishes amethyst from other quartz varieties like citrine (which is iron-rich but heated) or rose quartz (which gets its color from titanium and iron).
Hardness and Durability: On the Mohs scale of mineral hardness, amethyst ranks a 7. This places it among the harder gemstones, making it resistant to scratching and suitable for a variety of jewelry applications. However, like all gemstones, it is not indestructible. It can be chipped or broken if struck with sufficient force. Its lack of cleavage (a tendency to break along specific planes) is an advantage, as it reduces the risk of accidental breakage during setting or wear. With a specific gravity of approximately 2.65, amethyst is relatively lightweight for its size, which is beneficial for larger statement pieces.
Color and Clarity: The color of amethyst is its most defining feature, ranging from light lilac to deep reddish-purple. The most prized colors are those with a rich, saturated violet hue, often described as "Siberian" in reference to the historic Russian deposits. Color zoning, where lighter and darker areas appear in the same stone, can occur, but high-quality amethyst typically exhibits an even color distribution. Clarity is another important factor; amethyst is generally "eye-clean," meaning it lacks visible inclusions to the naked eye. Inclusions, if present, are often needle-like or feather-like and do not typically detract from the stone's beauty unless they are large or numerous.
Cut and Carat: Amethyst is cut into a wide variety of shapes and styles to maximize its color and brilliance. Common cuts include round, oval, pear, and emerald cuts, as well as cabochons for opaque specimens. The cut is crucial for enhancing the stone’s color saturation, as lighter amethyst may be cut deeper to concentrate the hue. Amethyst is available in a broad range of carat weights, from small accent stones to large centerpiece gems. Due to its relative abundance, larger amethyst stones are more accessible than many other colored gemstones, allowing for dramatic and affordable jewelry designs.
Refractive Index and Optical Properties: Amethyst has a refractive index of approximately 1.54 to 1.55, which is typical for quartz. It exhibits double refraction (birefringence) and may show a weak pleochroism, displaying slight color variations when viewed from different angles. These optical properties contribute to its brilliance and fire when properly cut.

Symbolism and Metaphysical Beliefs
Beyond its physical beauty and gemological attributes, amethyst is steeped in symbolism and metaphysical beliefs that have evolved over millennia. These associations have contributed significantly to its enduring popularity as a birthstone and a gem for personal adornment.
The most ancient symbolism of amethyst is its connection to sobriety and clarity of mind, as reflected in its Greek name. This belief persisted into the Middle Ages, where soldiers and hunters would often wear amethyst amulets or drink from cups carved from the stone, believing it would protect them from intoxication and keep their minds clear. This association with mental clarity has expanded in modern metaphysical circles to include enhanced focus, memory, and decision-making. For those born under the sign of Aquarius, amethyst is said to stimulate creativity and innovative thinking, while for Pisceans, it is believed to enhance intuition and emotional understanding.
Amethyst is also widely regarded as a stone of spirituality and peace. Its purple color, historically linked to royalty, is also associated with the crown chakra in Eastern spiritual traditions, which governs enlightenment and spiritual connection. Many believe that amethyst can facilitate meditation, promote inner peace, and protect against negative energies. It is often used as a calming stone to alleviate stress, anxiety, and nightmares, fostering a sense of tranquility and emotional balance. This makes it a popular choice for jewelry worn during periods of emotional upheaval or as a tool for spiritual practice.
In addition to its mental and spiritual benefits, amethyst is traditionally associated with physical healing and protection. Some beliefs hold that it can support the immune system, improve sleep quality, and aid in detoxification. While these claims are not scientifically verified, they are part of the rich cultural tapestry that surrounds the stone. The symbolism of protection is particularly strong; amethyst was once thought to protect travelers from harm and to ward off evil spirits. This protective quality, combined with its association with love and fidelity, has made amethyst a meaningful gift for loved ones, symbolizing a bond that is both deep and safeguarded.
For February-born individuals, amethyst serves as a personal talisman that embodies the qualities of their birth month: clarity, protection, and spiritual growth.
