February and March mark the transition from winter to spring, and their birthstones reflect this transformation. While February’s birthstone, amethyst, has long been revered for its regal purple hues and spiritual symbolism, March’s aquamarine dazzles with its serene blue tones and protective qualities. Both gemstones have rich histories, unique gemological properties, and deep cultural significance. This article explores the origins, symbolism, and scientific attributes of these two birthstones, drawing on the historical and gemological data provided by authoritative sources.
History and Lore
Amethyst: The Stone of Sobriety and Clarity
Amethyst, the birthstone for February, has a storied history that spans millennia. Its name derives from the Greek amethystos, meaning “not drunk,” a reference to the belief that wearing amethyst could prevent intoxication. Ancient Greeks and Romans often drank wine from amethyst goblets, believing the gemstone would protect 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 grew during the Roman Empire, where it was frequently used in signet rings and cameos. By the Middle Ages, amethyst was considered a sacred stone and was associated with the Catholic Church, often used in ecclesiastical jewelry. During the 18th and 19th centuries, amethyst became a fashionable gemstone in Europe, especially among royalty and the aristocracy, thanks to its availability in large sizes and its striking color.
Amethyst’s spiritual and therapeutic properties have also been widely recognized. In many cultures, it is believed to aid in meditation, reduce stress, and enhance one’s ability to think clearly and act decisively. These beliefs have contributed to its enduring appeal, not only in jewelry but also in the realm of holistic healing.
Aquamarine: The Stone of the Sea
Aquamarine, the birthstone for March, shares a similarly storied past, though it is perhaps less well known than amethyst. Its name, meaning “water of the sea” in Latin (aqua marina), reflects its color, which ranges from pale blue to a more intense greenish-blue. Ancient mariners believed that carrying aquamarine would ensure safe passage across the sea and protect them from storms. This belief was so widespread that sailors often wore aquamarine amulets during long voyages.
Aquamarine was also believed to promote courage and happiness, particularly in love and marriage. In medieval Europe, it was considered a symbol of fidelity and was often used in engagement rings. The gemstone’s association with purity and protection continued into the Renaissance and Baroque periods, during which it was frequently featured in religious and royal jewelry.
Modern interest in aquamarine was rekindled in the 20th century, especially after the discovery of large deposits in Brazil in the 19th century. These deposits made the gemstone more accessible and affordable, leading to a surge in its popularity in jewelry design. Today, aquamarine is cherished not only for its beauty but also for its historical and cultural significance.
Geological Formation and Sources
Amethyst: A Variety of Quartz
Amethyst is a variety of quartz, composed of silicon dioxide (SiO₂). It is typically found in geodes and cavities within volcanic rocks, where it forms over long periods through the slow crystallization of silica-rich solutions. The characteristic purple color of amethyst is caused by the presence of iron impurities and exposure to natural radiation. The intensity of the color can vary depending on the concentration of these impurities and the duration of radiation exposure.
Amethyst is found in many parts of the world, including Brazil, Uruguay, Zambia, and Russia. Brazil, in particular, is one of the largest producers of high-quality amethyst, with major deposits in the states of Rio Grande do Sul and Minas Gerais. These regions produce some of the most vibrant and well-formed amethyst crystals available in the market.
Aquamarine: A Beryl with a Blue Twist
Aquamarine is a member of the beryl family, which also includes emerald. Like emerald, aquamarine is composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆), with its blue coloration derived from trace amounts of iron. The gemstone is typically found in granitic pegmatites, which are igneous rocks formed from the slow cooling of magma. The presence of beryllium and iron in these pegmatites allows for the formation of aquamarine crystals.
Brazil is the primary source of aquamarine, with significant deposits in the states of Minas Gerais and Bahia. Other notable sources include Nigeria, Pakistan, Afghanistan, and the United States. The most famous aquamarine deposit is the “Empress of Brazil” mine in Minas Gerais, which has produced some of the finest examples of the gemstone.

It is also thought to have a calming effect on the body, helping to reduce anxiety and promote a sense of calm.
Care and Cleaning
Amethyst
Due to its hardness of 7 on the Mohs scale, amethyst is relatively durable but still requires proper care to maintain its beauty. It should be cleaned with warm, soapy water and a soft cloth or brush. Ultrasonic and steam cleaners can be used, but they should be done with caution, especially if the amethyst has been heat-treated, as these methods can cause thermal shock.
Amethyst should be stored separately from harder gemstones to prevent scratches. It is also sensitive to prolonged exposure to direct sunlight, which can cause fading, so it should be kept out of direct sunlight when not in use.
Aquamarine
Aquamarine is slightly harder than amethyst, with a hardness of 7.5–8 on the Mohs scale, making it even more durable. It can be cleaned using the same methods as amethyst, including warm, soapy water, ultrasonic, and steam cleaners. However, like amethyst, it should be kept away from harsh chemicals and abrasive materials.
Aquamarine should also be stored separately from other gemstones to prevent scratches. It is relatively stable in color and does not fade easily, but it is still advisable to avoid prolonged exposure to direct sunlight to ensure its longevity.
