For those born on March 17th, the designated birthstone is aquamarine, a gem whose name translates from the Latin aqua marina to "water of the sea." This connection is not merely linguistic; the stone’s serene blue to blue-green hues directly evoke the calm, crystalline waters of the ocean, making it a perfect emblem for the month of March, which heralds the arrival of spring. Aquamarine belongs to the beryl mineral family, placing it alongside esteemed gems like emerald and morganite, yet it possesses a unique character defined by its clarity, color, and deep cultural resonance. As a birthstone, it is more than a decorative object; it is a symbol of wisdom, emotional balance, and protection, with a history stretching back to ancient civilizations that viewed it as a divine gift from the gods of the sea. This article provides a comprehensive exploration of aquamarine, detailing its historical journey, geological origins, gemological properties, and the symbolic meanings that have cemented its status as a cherished gem for centuries. We will also offer practical guidance on its care, ensuring that its luminous beauty endures for generations.
History and Lore
The historical narrative of aquamarine is intrinsically linked to humanity's relationship with the ocean, a connection that has shaped its symbolism for millennia. Its name, a direct reference to the sea, underscores this enduring association. In ancient Greece, aquamarine was revered as a gemstone bestowed by the gods, particularly Poseidon, the deity of the sea. Sailors and travelers embarked on long and perilous voyages often carried aquamarine talismans, believing the stone offered divine protection against the dangers of the open water. This belief was not confined to the Greeks; across many maritime cultures, aquamarine was considered a stone of safe passage, capable of warding off storms and ensuring a calm journey. The gem’s reputation for promoting calm, tranquility, and courage was thought to stem directly from its connection to the powerful yet serene nature of the sea.
Beyond its protective qualities, aquamarine has been revered for its perceived healing properties throughout history. Ancient practitioners and mystics believed the stone could calm the mind, soothe turbulent emotions, and bring clarity to its wearer. It was often associated with the ability to sharpen intuition and promote clear, honest communication. This multifaceted symbolism—encompassing protection, emotional stability, and mental clarity—has allowed aquamarine to maintain its significance from antiquity to the present day. Its journey from a sailor's protective charm to a modern birthstone is a testament to its enduring appeal and the universal human desire to find meaning and security in the natural world.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with the chemical formula Be₃Al₂Si₆O₁₈. Its characteristic blue color is trace amounts of iron within its crystalline structure. The gem forms in pegmatite deposits, which are coarse-grained igneous rocks that develop in the final stages of a magma chamber's crystallization. These environments provide the necessary conditions—high pressure, temperature, and the presence of volatile elements—for beryl crystals to grow to impressive sizes. Large, well-formed aquamarine crystals are particularly prized for their potential to be cut into substantial gemstones.
While aquamarine can be found in various locations around the world, certain regions are renowned for producing the highest quality specimens. Brazil is the leading source of aquamarine, with states like Minas Gerais and Rio Grande do Sul yielding some of the finest gems. Other significant sources include Madagascar, Nigeria, Pakistan, and Mozambique. The most valuable aquamarines are those with a deep, saturated blue color, often described as "Santa Maria" aquamarine, a term that originated for gems from the Santa Maria de Itabira mine in Brazil. However, it is important to note that natural aquamarine is typically found in lighter, paler shades of blue. The intense, vivid blue of many stones in the market is often the result of heat treatment, a standard and accepted industry practice that enhances the color by removing yellow or green tints.
Gemological Properties
Understanding the physical and optical characteristics of aquamarine is essential for appreciating its value and ensuring its proper care. As a member of the beryl family, it shares some properties with emerald but differs significantly in terms of clarity and color stability.

Color: The most defining feature of aquamarine is its color, which ranges from a very pale, almost colorless blue to a deep, saturated blue-green. The finest gems exhibit a pure, medium-dark blue with a slight greenish undertone. As noted in gemological resources, aquamarine crystals are generally very pale in color to almost transparent and are rarely found naturally in darker blue shades. The light blue color is the primary shade associated with the March birthstone.
Clarity: One of aquamarine's significant advantages over its cousin, emerald, is its typical clarity. While it can contain inclusions, it is far less likely to have the heavily included "jardin" (garden) characteristic of emeralds. Common inclusions in aquamarine are liquid-filled cavities, needle-like crystals, and mica flakes. Well-cut aquamarine is prized for its exceptional transparency and eye-clean appearance.
Hardness and Durability: With a hardness of 7.5 to 8 on the Mohs scale, aquamarine is a durable gemstone suitable for all types of jewelry, including rings and bracelets that are subject to daily wear. Its hardness makes it resistant to scratching, but like all gemstones, it can be damaged by a sharp blow due to its imperfect cleavage.
Cut and Carat: Aquamarine is often cut into classic shapes like emerald cuts, rounds, and ovals to maximize its color and clarity. Larger crystals allow for the creation of impressive faceted gems, and aquamarines over 5 carats are relatively common, making them an excellent choice for statement jewelry.
Symbolism and Metaphysical Beliefs
The symbolism of aquamarine is as deep and layered as the ocean it represents. Its primary associations are with tranquility, clarity, and protection. The stone is believed to have a calming effect on the mind and emotions, helping to reduce stress and anxiety. This property is directly linked to its historical use by sailors; the calm needed to navigate treacherous waters was thought to be imbued within the gem itself.
In metaphysical traditions, aquamarine is often called the "stone of courage." It is said to encourage the wearer to face their fears and speak their truth with confidence and clarity. This makes it a powerful stone for those in professions requiring public speaking or difficult conversations. Its connection to the throat chakra further emphasizes its role in facilitating honest and compassionate communication.
For individuals born in March, particularly under the zodiac sign of Pisces (February 20 - March 20), aquamarine is considered a primary birthstone. Pisces, a water sign, shares a natural affinity with aquamarine’s fluid, emotional, and intuitive qualities. The stone is believed to enhance the innate compassion and creativity of Pisces while providing a stabilizing influence. The alternative March birthstone, Bloodstone, is associated with Aries (March 21 - April 19), representing a different facet of March's energy—strength and vitality. This duality reflects the varied influences of the month, with aquamarine offering its serene wisdom to those born under its influence.
Care and Cleaning
Due to its good hardness and lack of cleavage, aquamarine is relatively easy to care for, but it is not invulnerable. Proper maintenance will ensure the gemstone retains its brilliance and color for a lifetime.
Daily Care: Aquamarine jewelry can be worn daily, but it is advisable to remove it during activities that could subject it to hard knocks or exposure to harsh chemicals, such as gardening, cleaning, or vigorous sports. While it is resistant to most chemicals, prolonged exposure to acids or strong detergents could dull its surface over time.
Cleaning Methods: The safest way to clean aquamarine is with warm, soapy water and a soft brush. A soft cloth or a soft-bristled brush can be used to gently scrub the gemstone and its setting to remove any accumulated dirt, oils, or debris. After cleaning, rinse the jewelry thoroughly under warm running water to ensure no soap residue remains, and then dry it with a soft, lint-free cloth.
What to Avoid: It is critical to avoid using ultrasonic cleaners and steamers for aquamarine. While the stone itself is relatively stable, sudden temperature changes and vibrations can potentially damage the gem or its setting. Furthermore, aquamarine is sensitive to heat and prolonged exposure to direct sunlight, which can cause the stone's color to fade over time. It should not be exposed to hot water for extended periods. When storing aquamarine jewelry, keep it separately from other pieces in a soft-lined jewelry box or a cloth pouch to prevent scratches from harder gems like diamonds or sapphires.
Conclusion
Aquamarine stands as a gemstone of profound beauty and significance, perfectly embodying the essence of March 17th. Its name, derived from the sea, is a direct link to a rich history of protection, courage, and calm that has been cherished by sailors and mystics alike. As a variety of beryl, it boasts impressive gemological properties, including a desirable hardness that makes it suitable for everyday jewelry, coupled with a clarity that allows its serene blue light to shine unimpeded. Its symbolism of wisdom, emotional balance, and clear communication continues to resonate with modern wearers, especially those born under the water sign of Pisces. By understanding its origins, properties, and the care it requires, owners of this beautiful gem can ensure that their aquamarine remains a treasured talisman of tranquility and elegance for years to come.
