Aquamarine, the designated birthstone for the month of March, is a gemstone celebrated for its distinct, tranquil blue hue and its profound connection to maritime lore. Its name, derived from the Latin words aqua (water) and maris (sea), directly translates to "water of the sea," a moniker that perfectly encapsulates its color palette, which ranges from the palest sky blue to the deep, saturated blues of the ocean's depths. As a member of the beryl family—the same mineral group that includes emeralds and morganite—aquamarine possesses remarkable durability, making it an excellent choice for jewelry that is meant to be worn and cherished daily. Its value lies not only in its physical beauty and gemological resilience but also in the rich tapestry of symbolism and history that has been woven around it for centuries. From a gem of sailors' protection to a modern emblem of clarity, calm, and new beginnings, aquamarine holds a unique position in the world of colored stones. This article will explore the multifaceted nature of aquamarine, delving into its historical significance, geological origins, distinct gemological properties, and its enduring role as the celebrated birthstone for March.
History and Lore
The history of aquamarine is deeply intertwined with the sea, a connection that has shaped its cultural significance from antiquity to the present day. The very name of the gemstone points to its ancient association with water and the ocean. This link was not merely poetic; for centuries, aquamarine was believed to possess powerful protective qualities, particularly for those who ventured out onto the water. Sailors of antiquity and the Middle Ages held the gem in high esteem, regarding it as a "treasure of the sea" that could ensure a safe passage and calm storms. They believed the stone had the power to calm the waves and protect them from peril, making it a talisman of immense value for maritime travel and trade.
Beyond its practical use as a protective amulet for seafarers, aquamarine was also attributed with a range of other symbolic meanings. In ancient times, it was thought to be an effective antidote for poison and was believed to influence the mind positively, promoting clarity of thought and spiritual awareness. The gem was often linked to happiness and everlasting youth, and some lore suggested it could rekindle the passion in a marriage or relationship. This blend of protective, mental, and emotional attributes made aquamarine a highly sought-after stone for royalty and nobility, who often adorned themselves with it to project an image of serenity and power.
The journey of aquamarine to its modern status as a March birthstone is a more recent development, codified in 1912 by the American National Association of Jewelers. This formalization helped solidify its place in contemporary culture, but its roots extend far deeper into the collective human imagination. The gem's association with the month of March is particularly fitting, as the month often signals the transition from the harshness of winter to the promise of spring, mirroring the stone's symbolism of fresh starts and renewal. The calming, clear blue of aquamarine serves as a visual metaphor for the clear skies and calmer seas that are hoped for as the season changes. The gem's lore has evolved from a tangible protector against physical dangers at sea to a more abstract symbol of emotional balance, inner peace, and the courage to embark on new chapters in life. This enduring symbolism is what makes aquamarine not just a beautiful gem, but a meaningful one for those born in March and anyone who wears it.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its characteristic blue coloration resulting from trace amounts of iron within its crystal structure. The presence and valence state of this iron element determine the specific shade of blue, from the pale, delicate greens of some stones to the intensely saturated blues that command the highest value. The formation of large, high-quality aquamarine crystals requires specific and often complex geological conditions, typically found deep within the Earth's crust. These conditions involve the slow cooling of magma-rich fluids that are rich in elements like beryllium, aluminum, silicon, and oxygen, along with the crucial trace amounts of iron. As these fluids travel through fractures and cavities in the surrounding rock, they slowly deposit the minerals that form beryl crystals over millions of years. This slow crystallization process is what allows for the growth of large, often inclusion-free crystals that are ideal for cutting into significant gemstones.
While beryl is found in many parts of the world, the most significant and historically important sources for high-quality aquamarine are concentrated in a few key regions. Brazil has long been recognized as the world's leading producer of aquamarine, with major mining operations in the states of Minas Gerais, Bahia, and Espírito Santo. The crystals found in these regions are renowned for their size and exceptional clarity, with some legendary specimens yielding gems of several hundred carats.
Other notable sources that contribute to the global supply of aquamarine include Pakistan, particularly the Skardu region, which is known for producing stones with a rich, deep blue color. African countries such as Nigeria, Mozambique, and Madagascar also yield significant quantities of aquamarine, often with unique color characteristics. In the United States, aquamarine has been found in locations like Mount Antero in Colorado, though production there is more limited. The specific geological conditions in each of these locations can influence the final color and quality of the gemstones, leading to a diverse range of aquamarine available in the market. The mining process often involves both large-scale industrial operations and smaller, artisanal mining efforts, all of which contribute to bringing this "water of the sea" to the surface for lapidaries and jewelers to transform into stunning pieces of jewelry.
Gemological Properties
Understanding the gemological properties of aquamarine is essential for appreciating its value as a gemstone and for making informed decisions when purchasing or caring for aquamarine jewelry. Its combination of hardness, clarity, and color makes it a favorite among both jewelers and consumers. The following table summarizes its key physical and optical characteristics.

As a member of the beryl family, aquamarine shares many properties with its famous green cousin, the emerald. However, a key difference often lies in its clarity. While emeralds are famously included, aquamarine is typically characterized by a higher degree of clarity, with fewer visible inclusions. This inherent clarity is one of the reasons it is so prized; the eye can often see directly through the stone, enhancing the perception of its watery depths and allowing light to interact with the gem in a way that maximizes its brilliance.
Its hardness on the Mohs scale of 7.5 to 8 makes aquamarine a durable gemstone, resistant to scratching and suitable for everyday wear in rings, earrings, and pendants. Only a few other gems, such as diamond, sapphire, and ruby, are harder. This durability means that an aquamarine ring can withstand the rigors of daily life with proper care. The gem's hexagonal crystal system means that it often forms as long, prismatic crystals, which lapidaries can cut to best display the stone's color and optical properties. The most common cut for aquamarine is the emerald cut, a rectangular step cut that emphasizes the stone's clarity and deep color, but it is also frequently found in brilliant cuts and other fancy shapes. The color of aquamarine, caused by iron, is its most defining feature. The most desirable colors are a deep, saturated blue with a slight hint of green, often referred to as "Santa Maria" aquamarine, named after a famous mining district in Brazil. Lighter blues are also popular and are often enhanced by heat treatment to remove greenish tones, a standard and accepted practice in the gem trade.
Symbolism and Metaphysical Beliefs
The symbolism and metaphysical beliefs surrounding aquamarine are as deep and varied as the gem's color. Its primary association with the sea has imbued it with a rich spiritual and emotional significance that continues to resonate with people today. Historically, as noted, it was a talisman of protection for sailors. This protective quality has evolved in modern metaphysical beliefs to encompass a broader sense of emotional and spiritual safeguarding. It is widely regarded as a stone of courage, believed to calm fears and soothe anxieties, allowing the wearer to navigate life's challenges with a clear mind and a steady heart. The calming nature of its color is thought to translate into a calming energy, making it a popular choice for those seeking to reduce stress and promote tranquility in their lives.
Beyond courage and protection, aquamarine is strongly linked to the concept of clarity. This symbolism applies to both mental and emotional clarity. It is believed to help its wearer achieve a state of mental clarity, enhancing focus and intellectual acuity. On an emotional level, it is said to help clear away cloudy or confused feelings, promoting honest self-expression and the ability to understand one's own true feelings. This makes it a powerful stone for communication, both with others and with oneself. The gem is also associated with the throat chakra, the energy center related to communication, and is often used by those who wish to speak their truth with greater confidence and eloquence.
Furthermore, aquamarine is considered a stone of renewal and fresh beginnings. Its connection to water, the source of all life, gives it a symbolic power to cleanse and rejuvenate the spirit. It is often recommended for anyone starting a new venture, moving to a new place, or beginning a new relationship, as it is thought to bring a sense of hope and the promise of new chapters. In some beliefs, it is also connected to the heart, where it is said to help heal emotional wounds and promote loving, compassionate communication within partnerships. Whether one subscribes to these metaphysical beliefs or simply appreciates the gem for its physical beauty, the symbolism of aquamarine adds a compelling layer of depth to its appeal, making it a meaningful gift and a cherished personal adornment.
Care and Cleaning
The durability of aquamarine, stemming from its respectable hardness of 7.5 to 8 on the Mohs scale, makes it a relatively low-maintenance gemstone suitable for a wide range of jewelry applications. However, proper care is still necessary to ensure that an aquamarine piece retains its beauty and sparkle for generations. Because it is a durable stone, it is less susceptible to scratching and abrasion than many other gems, but it is not indestructible. It is wise to store aquamarine jewelry separately from other pieces, especially those made with harder stones like diamonds or softer stones that could be damaged by it, to prevent scratching or being scratched.
When it comes to cleaning aquamarine, the process is straightforward and can be done safely at home. The best method is to use warm, soapy water and a soft brush, such as a baby toothbrush or a soft-bristled jewelry brush. Gently scrub the gemstone and its setting to remove any accumulated oils, lotions, or dirt. It is important to avoid harsh chemicals, as these can damage not only the stone but also the metal of the setting. Specifically, one should avoid using bleach, chlorine, and other abrasive cleaners. Ultrasonic cleaners are generally considered safe for aquamarine, provided the stone has no significant fractures or inclusions. However, steam cleaning is not recommended, as the sudden and intense temperature changes can potentially cause damage to the gem.
For aquamarine jewelry that features other stones or is set in delicate metals, it is always best to exercise caution. If the piece contains other gems with lower hardness or greater fragility, such as opals or pearls, the cleaning method should be tailored to the most delicate component. As with any fine jewelry, it is advisable to have the piece inspected periodically by a professional jeweler to ensure that the setting is secure and that the gemstone is not at risk of being lost. With this simple care, an aquamarine ring or other piece of jewelry will continue to capture the serene essence of the sea, serving as a beautiful and enduring symbol for the March birthstone.
