Aquamarine, the primary birthstone for the month of March, is a gemstone celebrated for its tranquil blue hues and deep connections to the sea. Its name, derived from the Latin words aqua (water) and marina (sea), perfectly encapsulates the stone’s captivating color, which ranges from pale, almost transparent tints to deeper greenish-blues. As a member of the beryl family, aquamarine shares its mineral lineage with other precious stones such as emerald and morganite, yet it possesses a distinct character that has made it a favorite among jewelers and collectors for centuries.
While aquamarine stands as the principal birthstone for March, the month is also associated with an alternative gem: bloodstone. These two stones, vastly different in appearance and composition, both carry rich histories and symbolic meanings. Aquamarine, however, is particularly resonant with those born under the zodiac sign of Pisces, especially on March 14th, a date that is said to amplify the stone's attributes of clarity, leadership, and intuitive wisdom. This article will provide a comprehensive exploration of aquamarine, detailing its historical lore, geological origins, gemological properties, and its enduring significance as a symbol of serenity and courage.
History and Lore
The history of aquamarine is deeply intertwined with maritime lore and the civilizations that thrived along the Mediterranean. Ancient mariners were among the first to revere this gemstone, believing it to be the treasure of mermaids. They carried aquamarine amulets engraved with the image of Neptune, the Roman god of the sea, as talismans for protection, believing the stone would calm turbulent waves and ensure a safe voyage. This association with the ocean cemented its reputation as a stone of calm, peace, and emotional clarity, embodying the soothing nature of the sea.
The etymology of aquamarine reflects this connection. The name, meaning "seawater," was bestowed upon the stone by the Romans, who held it in high regard. Both the Greeks and Romans utilized aquamarine not only for its beauty but also for its perceived powers. It was used as a talisman for good luck and prosperity and was associated with Venus, the goddess of love and beauty. The Romans believed that if an aquamarine was immersed in water, it could cure ailments such as poisoning and illness, further enhancing its value as a curative and protective stone. Its popularity has endured through the ages, continuing to be a favored choice for a wide array of jewelry designs.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its characteristic blue-to-greenish-blue coloration resulting from trace amounts of ferrous iron within its chemical structure. The most prized and valuable aquamarine crystals are found in large, well-formed hexagonal prisms. These crystals are typically formed in pegmatite deposits, which are coarse-grained igneous rocks that allow for the growth of large, high-quality gemstones.
The primary sources of high-quality aquamarine are found in Brazil, particularly in the states of Minas Gerais and Bahia. Brazil is renowned for producing large, transparent crystals in a range of blue hues. In 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a dark blue, rectangular step-cut aquamarine weighing 1,298 carats, a testament to the country's ability to produce exceptional specimens.
Beyond Brazil, significant deposits are also found in other parts of the world. Nigeria and Zambia in Africa are major producers, often yielding stones with deeper, more saturated colors. Other sources include Madagascar, Pakistan, and Mozambique. The geological conditions in these regions allow for the formation of aquamarine crystals that are prized for their clarity and color saturation.
Gemological Properties
Aquamarine is valued for its durability, clarity, and beautiful color, making it an excellent choice for all types of jewelry. As a member of the beryl family, it possesses a hardness of 7.5 to 8 on the Mohs scale, indicating a high resistance to scratching and abrasion. This durability ensures that aquamarine jewelry can withstand daily wear with proper care.
The color of aquamarine is its most defining characteristic. It ranges from blueish green, blue-green, and greenish blue to deep blue. The most desirable color is a deep, pure blue, reminiscent of a tropical ocean. The color intensity can vary, and while many aquamarine crystals are naturally pale, some can be treated with heat to enhance their blue color. If a very pale aquamarine is irradiated to darken the blue color, it is then known as blue beryl. The gemstone's clarity is another notable feature; faceted aquamarines are often free from inclusions and as clear as water, symbolizing purity of spirit and soul.
The chemical composition of aquamarine is Be₃Al₂Si₆O₁₈, with iron impurities causing the blue color. Its refractive index and specific gravity are typical of the beryl group. The gem is often found in large carat sizes, making it a popular choice for statement pieces.

Symbolism and Metaphysical Beliefs
Throughout history, aquamarine has been imbued with a wide range of symbolic meanings and metaphysical beliefs. Its primary association is with the sea, and by extension, with emotions, intuition, and tranquility. The stone is widely regarded as a symbol of courage, honesty, and clarity. Ancient lore held that it could calm the mind, soothe fears, and reduce stress, making it a powerful tool for meditation and spiritual healing.
For those born in March, and particularly for Pisces, aquamarine is believed to complement the compassionate and forgiving nature of the sign. It is thought to enhance intuitive wisdom and creative exploration. The connection to the Pisces zodiac sign further reinforces the gemstone’s association with the sea and its calming, restorative properties.
Specific energies are also attributed to those born on March 14th. It is said that individuals born on this date embody the gemstone’s clarity and fresh spring energy. The stone is believed to bring them new season leadership, creative exploration, and intuitive wisdom. Sharing a birthday with notable figures like Albert Einstein adds a layer of intellectual curiosity and innovation to the day's symbolism, and aquamarine is thought to support these qualities.
In addition to its emotional and spiritual benefits, aquamarine was also believed to have physical healing properties. Ancient healers thought it could cure ailments related to the throat, jaw, and teeth, and was used to treat conditions such as poisoning and illness.
Care and Cleaning
Due to its good hardness and lack of cleavage, aquamarine is a relatively durable gemstone that is easy to care for. It is suitable for all jewelry types, including rings, necklaces, bracelets, and earrings, and can be worn daily without significant risk of damage.
To clean aquamarine jewelry, use warm, soapy water and a soft brush. Be sure to rinse the stone thoroughly to remove any soap residue, which can leave a film on the surface. Ultrasonic and steam cleaners are generally safe for aquamarine, provided the stone does not have any fractures or inclusions that could be damaged by the vibrations or heat. It is always advisable to inspect the jewelry's setting before using these cleaning methods.
While aquamarine is resistant to heat and chemicals, it is still important to protect it from sharp blows and extreme temperature changes, which could potentially damage the stone or its setting. Storing aquamarine jewelry separately from other gems will prevent it from being scratched by harder stones.
Conclusion
Aquamarine stands as a captivating gemstone, rich in history, symbolism, and geological significance. Its serene blue hues, durable properties, and association with courage, honesty, and tranquility make it a cherished birthstone for March. From ancient sailors seeking protection at sea to modern jewelry enthusiasts appreciating its beauty, aquamarine continues to captivate and inspire, embodying the timeless allure of the ocean and the enduring power of gemstones. For those born on March 14th, it holds an even deeper resonance, serving as a symbol of clarity, leadership, and intuitive wisdom.
