The transition from winter to spring is marked by a shift in color and energy, a phenomenon perfectly mirrored in the birthstones of February and March. February is represented by the regal purple of amethyst, a gemstone long associated with clarity, calmness, and historical nobility. March is heralded by the serene blue of aquamarine, evoking the clarity of spring skies and the protective qualities of flowing waters. Both gemstones possess deep historical roots, distinct gemological characteristics, and enduring cultural significance. This article delves into the origins, lore, geological formation, and scientific properties of these two captivating birthstones, providing a comprehensive guide for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
Amethyst: The Stone of Sobriety and Clarity
Amethyst, the primary birthstone for February, boasts a history that spans millennia. Its name is derived from the Greek word amethystos, which translates to “not drunk.” This etymology is rooted in a profound ancient belief: that wearing amethyst could prevent intoxication. Ancient Greeks and Romans were known to drink wine from amethyst goblets, convinced the gemstone would shield them from the effects of alcohol. Beyond its association with sobriety, amethyst was also believed to ward off evil and promote mental clarity and calmness.
The gemstone’s popularity surged during the Roman Empire, where it was frequently incorporated into signet rings and cameos. By the Middle Ages, amethyst was considered a sacred stone, closely associated with the Catholic Church and often used in ecclesiastical jewelry. This historical reverence for amethyst underscores its long-standing value, which was once so high that it was considered a precious gemstone on par with diamonds and sapphires. The sources note that one had to be affluent to own this birthstone, but new geological discoveries have since made it more accessible and affordable.
Aquamarine: The Gem of the Sea and Spring
March’s birthstone, aquamarine, draws its name and identity from the Latin words aqua (water) and marina (of the sea). Its ocean-like blue hues symbolize renewal, safety, and the arrival of spring, reflecting the month’s transitional energy from winter to warmer seasons. The lore surrounding aquamarine is deeply connected to the sea. Sailors historically carried it as a talisman for protection during voyages, believing it would ensure a safe passage and calm stormy waters. It was also thought to be a treasure of mermaids and a stone of courage and cleansing.
The symbolism of aquamarine is intertwined with its visual characteristics. Its serene blue tones are said to evoke clarity of thought and a peaceful state of mind, making it a gemstone of choice for those seeking emotional balance and spiritual insight. As a stone representing health and strength, aquamarine aligns with the vitality of early spring, capturing the essence of flowing waters and clear skies.
Geological Formation and Sources
Amethyst
Amethyst is a variety of the mineral quartz, specifically the purple variety of silica. Its color is primarily derived from trace amounts of iron and natural irradiation within the crystal lattice. The formation of amethyst occurs in geodes and cavities within volcanic and sedimentary rocks, where silica-rich fluids deposit crystals over time.
Significant sources of amethyst are found worldwide. The Four Peaks Mine in Maricopa County, Arizona, is highlighted as the most important amethyst mine in the United States, known for producing gems with a beautiful reddish-purple hue. The sources indicate that amethyst is mined globally, contributing to its widespread availability and making it one of the world's most popular purple gemstones.
Aquamarine
Aquamarine is the blue variety of the mineral beryl, a family that also includes emeralds and morganite. Its color ranges from a slightly greenish blue to a nearly pure blue hue. The blue coloration in aquamarine is due to trace amounts of iron within its crystal structure. Unlike amethyst, which forms in geodes, aquamarine typically forms in pegmatites—coarse-grained igneous rocks—where large crystals can develop under specific conditions of temperature and pressure.
Aquamarine is mined in various locations around the world, contributing to its global presence in the jewelry market. The sources mention that aquamarines are mined globally, allowing for a variety of options to fit different styles and preferences.

Amethyst Properties
Amethyst is the world's most popular purple gemstone. Its color can vary dramatically, from a light, barely perceptible violet to a deep, reddish purple that can make a faceted gem appear nearly opaque. This range in color intensity directly affects its value, with darker, more saturated hues typically being more prized. With a Mohs hardness of 7, amethyst is durable enough for most types of jewelry, though care should be taken to avoid sharp blows that could cause chipping.
Aquamarine Properties
Aquamarine is prized for its clarity and color. As a variety of beryl, it is naturally transparent and is almost always faceted to maximize its brilliance. The color spectrum for aquamarine is wide, from a very light, almost imperceptible blue to a rich, deep blue. The sources note that aquamarines with the purest blue color and richest saturation are the most popular, while lighter-colored stones are more affordable and equally enjoyed by many. Its hardness, typical for beryl, makes it a resilient gemstone suitable for rings, pendants, and earrings.
Symbolism and Metaphysical Beliefs
Amethyst
Beyond its historical lore, amethyst is deeply embedded in modern metaphysical beliefs. It is often called the "stone of spirituality and contentment" and is believed to possess calming energies. The sources describe it as a gem that "soothes the mind and purifies emotions," making it a perfect fit for February's introspective energy. It is associated with inner growth, quiet strength, and spiritual insight. For those born in February, amethyst is thought to promote mental clarity, emotional stability, and a deeper connection to one's spiritual self.

Its serene blue color is said to calm fears and reduce stress, promoting a sense of peace and tranquility. As a birthstone for March, it symbolizes the awakening of nature and the flow of life. It is believed to protect travelers, especially those on water, and to be a powerful tool for meditation, helping to clarify the mind and enhance spiritual awareness. The gemstone's association with health and strength aligns with the revitalizing energy of spring.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone. The cleaning methods for amethyst and aquamarine are similar, given their comparable hardness, but specific considerations should be noted.
Caring for Amethyst
With a Mohs hardness of 7, amethyst is relatively durable. It is safe to clean with warm, soapy water and a soft brush. However, it is important to avoid prolonged exposure to strong sunlight or heat, as these can cause the purple color to fade over time. Therefore, it is advisable to store amethyst jewelry away from direct sunlight and to remove it before activities like sunbathing or using tanning beds.
Caring for Aquamarine
Aquamarine, with a hardness typically between 7.5 and 8, is also quite durable and suitable for everyday wear. It can be cleaned using the same method as amethyst: warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally safe for aquamarine, but it is always wise to check with a professional jeweler first, especially if the stone has any inclusions or treatments. Like amethyst, aquamarine should be protected from sharp blows and extreme temperature changes, which could potentially damage the stone or its setting.
