For those born on the cusp of Pisces and Aries, or simply during the month of March, aquamarine offers a connection to ancient lore, geological wonder, and enduring elegance. This article explores the multifaceted nature of the March 20th birthstone, delving into its historical significance, geological origins, gemological properties, symbolic meanings, and practical care.
History and Lore
The historical significance of aquamarine is deeply intertwined with its association with the sea. Ancient civilizations, particularly those reliant on maritime travel, revered this gemstone as a potent talisman. Sailors from antiquity believed that carrying or wearing aquamarine could ensure safe passage across treacherous waters, protect against storms, and calm the seas. This belief stemmed from the stone’s uncanny resemblance to the tranquil blues of the ocean, a visual connection that made it a natural symbol of seafaring life and exploration.
The name "aquamarine" itself, a direct reference to its watery aesthetic, underscores this ancient connection. The Latin phrase aqua marina perfectly encapsulates the gem’s serene and watery appearance. This historical lore is not merely anecdotal; it forms a foundational part of aquamarine’s identity as a birthstone. The stone’s reputation as a protector of travelers extended beyond the physical journey of sailors to include spiritual and emotional voyages, making it a symbol of courage and safety in the face of the unknown.
Beyond its maritime associations, aquamarine has been linked to the zodiac sign Pisces, which spans from February 20 to March 20. This astrological connection further solidifies its status as the March 20th birthstone. Pisces is often characterized by sensitivity, intuition, and a deep emotional connection to the world, traits that are reflected in aquamarine’s calming and fluid energy. The gemstone’s serene blue hues are said to evoke a sense of peace and tranquility, making it a popular choice for meditation and spiritual practices. In modern times, aquamarine continues to be considered a stone of peace, encouraging serenity and harmony, and is believed to bring courage, honesty, and loyalty to those born in March. This evolution from a practical sailor’s talisman to a symbol of inner peace and personal virtue illustrates the gemstone’s enduring appeal across different eras and cultures.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with the chemical formula Be₃Al₂Si₆O₁₈. It forms in pegmatite deposits, which are coarse-grained igneous rocks that provide the necessary environment for large crystals to develop. The presence of iron impurities within the beryl crystal structure is responsible for its characteristic blue to blue-green coloration. The intensity of the color can vary significantly based on the concentration and oxidation state of the iron, ranging from pale, almost colorless hues to a deep, saturated blue.
While the provided sources do not specify particular mining locations, they confirm that aquamarine is sourced from geological formations known for producing large, high-quality crystals. Pegmatite deposits are renowned in the gemological world for yielding some of the most significant gemstones ever discovered, including enormous aquamarine crystals. The formation process requires specific geological conditions, including a slow cooling rate and the presence of the right chemical elements (beryllium, aluminum, silicon, and iron) in a water-rich environment.
The quality of aquamarine is often judged by its color, with the most prized specimens exhibiting a deep, intense blue. However, the majority of aquamarine on the market today tends to be lighter in color. This variation in color intensity is a direct result of the specific geological conditions during its formation, including temperature, pressure, and the availability of iron. The gem’s excellent clarity and vitreous luster are also characteristic of beryl family minerals, contributing to its desirability for jewelry. The ability of pegmatites to produce large, gem-quality crystals means that aquamarine can be cut into sizable faceted stones, making it a popular choice for statement jewelry pieces such as rings, pendants, and earrings.
Gemological Properties
Aquamarine’s physical and optical properties make it a durable and attractive gemstone for a variety of jewelry applications. As a member of the beryl family, it shares many characteristics with its relatives, emerald and morganite, but possesses a distinct color profile.
Color: The defining feature of aquamarine is its blue to blue-green color. The hue is caused by trace amounts of iron within the crystal lattice. The color can range from very pale to a deep, vivid blue, with the most valued stones displaying a saturated, ocean-blue tone. Unlike some gemstones, aquamarine typically does not exhibit strong color zoning, contributing to its uniform appearance.
Hardness and Durability: On the Mohs scale of mineral hardness, aquamarine registers between 7.5 and 8. This places it among the harder gemstones, making it resistant to scratching and suitable for everyday wear in jewelry. Its durability is further enhanced by its lack of cleavage, a property that makes it less prone to breaking or chipping when struck, unlike gems such as diamond or topaz which have distinct cleavage planes.
Clarity: Aquamarine is known for its excellent clarity. It is typically classified as a "Type II" gemstone by the Gemological Institute of America (GIA), meaning it is usually found with fewer inclusions than Type I gems (like aquamarine’s cousin, emerald, which is Type III). Inclusions in aquamarine can include liquid-filled cavities, long needle-like crystals, and growth tubes. However, high-quality aquamarine is often eye-clean, meaning no inclusions are visible to the naked eye, allowing light to pass through unimpeded and enhancing its brilliance.
Luster and Refractive Index: Aquamarine possesses a vitreous (glass-like) luster, giving it a bright, reflective surface when properly cut. Its refractive index ranges from approximately 1.577 to 1.583, with a birefringence of 0.005 to 0.009. These optical properties contribute to its sparkle and fire when faceted. The gem is often cut in traditional shapes like rounds, ovals, emeralds, and cushions to maximize its color and brilliance.
Carat Weight: Aquamarine can form in very large crystals, which means it is available in a wide range of sizes. Larger stones are relatively common compared to other colored gemstones, allowing for the creation of impressive jewelry pieces without an exorbitant cost per carat for sizes that would be prohibitive in other gems.

Symbolism and Metaphysical Beliefs
Aquamarine’s symbolism is as fluid and deep as the waters it represents. Historically, its primary association was with protection and safety, particularly for those at sea. This ancient belief has evolved into a broader symbolism of courage, clarity, and communication. The gemstone is said to embody the qualities of serenity, truth, and emotional balance, making it a powerful tool for personal growth and introspection.
In modern metaphysical beliefs, aquamarine is often referred to as the "stone of courage." It is believed to soothe fears and phobias, particularly those related to water, and to provide a calming influence during stressful situations. Its connection to the throat chakra is also prominent, with practitioners suggesting that aquamarine can aid in clear communication, self-expression, and the articulation of one’s truth. This makes it a popular stone for public speakers, artists, and anyone seeking to enhance their communicative abilities.
The gem’s link to the zodiac sign Pisces reinforces its association with intuition and emotional depth. For individuals born under the sign of Pisces, or specifically on March 20th, aquamarine is thought to harmonize with their natural sensitivity and empathy. It is believed to help filter out emotional noise, allowing for greater clarity of thought and feeling. The stone’s calming energy is said to promote meditative states, making it a favored companion for spiritual practices and mindfulness exercises.
While these metaphysical beliefs are widely held within certain communities, it is important to note that they are based on tradition and personal belief rather than empirical scientific evidence. Nonetheless, they form an integral part of aquamarine’s cultural identity and its appeal as a meaningful birthstone. The stone’s symbolism of renewal and clarity is particularly resonant for those born in March, a month that marks the transition from winter to spring and the beginning of new growth.
Care and Cleaning
Due to its excellent hardness and lack of cleavage, aquamarine is a relatively durable gemstone that can maintain its beauty for generations with proper care. Its toughness makes it suitable for a variety of jewelry settings, including rings, which are subject to daily wear.
Cleaning: Aquamarine can be safely cleaned using warm water, a mild soap (such as dish detergent), and a soft brush. Gently scrubbing the stone and its setting will remove accumulated dirt and oils. It is crucial to avoid harsh chemicals, such as bleach or ammonia, which can damage the stone or its setting. Ultrasonic cleaners are generally safe for aquamarine, provided the stone is not included or fractured, as the vibrations could potentially exacerbate existing inclusions. Steam cleaning is also acceptable but should be done with caution, ensuring the stone is clean and free of oils before subjecting it to high-temperature steam.
