Aquamarine, the celebrated birthstone for March 8th, is a gemstone that captures the tranquil essence of the sea. A member of the beryl family, this gem is prized for its stunning blue to blue-green hues, a coloration derived from trace amounts of iron within its crystal structure. Its name, derived from the Latin words aqua (water) and marinus (sea), perfectly encapsulates its oceanic appearance. As one of March's two official birthstones, aquamarine holds a distinguished position in both the world of gemology and the realm of cultural symbolism. It is a stone associated with clarity, courage, and emotional balance, making it a meaningful choice for those born in the third month of the year. This article provides a comprehensive exploration of aquamarine, detailing its rich history, geological origins, distinct gemological properties, and the practical care required to preserve its enduring beauty.
History and Lore
The history of aquamarine is as deep and compelling as the gem's signature color. For centuries, it has been a source of fascination and reverence, woven into the myths and daily lives of numerous cultures. Ancient civilizations held the stone in high regard, believing it possessed powerful protective qualities. Sailors, in particular, were among its most devoted adherents. They carried aquamarine amulets and talismans, convinced that the stone would ensure safe passage across turbulent seas, calm waves, and protect them from the perils of the ocean. This maritime connection is a recurring theme throughout the gem's historical record, firmly establishing its reputation as a stone of the sea.
Beyond its use by mariners, aquamarine was also valued for its purported ability to ward off evil spirits and promote a sense of calm and tranquility. Both the Greeks and the Romans incorporated the gemstone into their jewelry, not only for its aesthetic appeal but also for its believed power to protect the wearer during times of conflict and turmoil. The stone was thought to be a powerful ally in promoting mental clarity and soothing the nerves, making it a favored gem for those seeking emotional stability and spiritual insight.
These ancient beliefs persisted through the Middle Ages and the Renaissance, where aquamarine continued to be incorporated into decorative arts and jewelry. It was believed to be a stone of clarity, peace, and protection, attributes that made it a popular choice for a wide range of applications. The gem's association with positive traits such as courage, communication, and serenity has ensured its continued popularity through the ages. Its designation as the primary birthstone for the entire month of March, and specifically for those born on March 8th, solidifies its long-standing cultural significance. For individuals born on this date, aquamarine is not merely a beautiful gem but a symbol of personal growth, wisdom, and emotional balance. This connection is further enriched by the fact that March 8th is also International Women’s Day, linking the stone to broader themes of empowerment and social progress.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, a cyclosilicate. Its chemical composition is primarily beryllium aluminum silicate (Be₃Al₂Si₆O₁₈), and it belongs to the same mineral family as emerald (green beryl), morganite (pink beryl), and heliodor (yellow beryl). The defining characteristic of aquamarine—its captivating blue to blue-green color—is the result of trace amounts of iron ions (Fe²⁺ and Fe³⁺) present within the beryl crystal lattice. The specific shade and intensity of the blue are influenced by the concentration and state of the iron impurities, as well as the conditions under which the crystal formed.
Aquamarine typically forms within large, hexagonal crystals that can be found in pegmatites, which are coarse-grained igneous rocks. These crystals can grow to impressive sizes, allowing for the cutting of large, high-quality gemstones that are highly sought after by collectors and jewelers. The clarity of aquamarine is often exceptional, with many faceted specimens appearing as "clear as water," a quality that enhances the gem's resemblance to a clear ocean or a pristine pool.
While beryl deposits are found in various locations around the world, certain regions are renowned for producing the finest aquamarine crystals. Brazil is a primary source, consistently yielding large, well-formed crystals with the desirable deep blue coloration. The historical gift of a large aquamarine from the Brazilian government to First Lady Eleanor Roosevelt in 1936 highlights the country's reputation for producing high-quality stones. Other significant sources include Pakistan, Madagascar, and several countries in Africa, each contributing to the global supply of this treasured gem. The geological conditions in these regions, particularly the presence of beryllium and aluminum along with iron under specific temperature and pressure regimes, are ideal for the formation of aquamarine.
Gemological Properties
Understanding the gemological properties of aquamarine is essential for appreciating its value, durability, and suitability for jewelry. As a member of the beryl family, it possesses a combination of physical characteristics that make it both beautiful and practical for everyday wear.
Color: The most sought-after color for aquamarine is a deep, saturated blue to a slightly greenish blue. Lighter, paler shades are more common and generally less valuable, although they are still highly appreciated for their delicate, ethereal quality. The stone's color is often described as serene and calming, evoking the tranquil waters of the sea.
Hardness and Durability: Aquamarine has a hardness of 7.5 to 8 on the Mohs scale of mineral hardness. This makes it a relatively hard and durable gemstone, suitable for a variety of jewelry types, including rings, earrings, necklaces, and bracelets. While it is resistant to scratching from most common materials, it can still be damaged by harder gems like diamonds or by sharp blows, so care should be taken to protect it from impact.
Clarity: One of aquamarine's most appealing attributes is its clarity. High-quality aquamarine is typically "eye-clean," meaning it is free from visible inclusions to the naked eye. This lack of internal flaws allows light to pass through the stone unimpeded, maximizing its brilliance and showcasing its beautiful color. Inclusions, when present, can affect both the stone's appearance and its value.
Cut and Carat Weight: Aquamarine's excellent clarity and strong pleochroism (the phenomenon of showing different colors when viewed from different angles) make it an ideal candidate for faceted cuts. Jewelers often use step cuts, such as the emerald cut, to enhance the stone's clarity and color. Due to the fact that large crystals are commonly found, aquamarine is available in a wide range of carat weights, from small stones for delicate pieces to massive centerpieces for statement jewelry.
Crystal System: Aquamarine crystallizes in the hexagonal system, a characteristic it shares with all beryl minerals. This results in the distinctive six-sided prismatic crystal shape often seen in raw aquamarine specimens.

Symbolism and Metaphysical Beliefs
The symbolism associated with aquamarine is as rich as its color. Rooted in ancient lore and carried into modern spiritual practices, the gem is widely regarded as a stone of emotional healing, clarity, and protection. Its connection to the sea is central to its metaphysical identity, linking it to the calming, cleansing, and ever-changing nature of the ocean.
Aquamarine is often called the "stone of courage." Historically, it was believed to instill courage and fortitude in its wearer, a quality that would have been invaluable to ancient sailors and warriors. This association with bravery continues today, with many believing that the gem can help overcome fear and anxiety, promoting self-confidence and clear communication.
Beyond courage, aquamarine is strongly linked to clarity of mind and emotional balance. It is believed to have a calming effect on the mind, helping to soothe stress, quiet mental chatter, and promote a state of inner peace. This makes it a popular stone for those seeking to enhance their meditation practice or to find emotional equilibrium during turbulent times. Its purported ability to open the channels of communication makes it a favored gem for those who wish to express themselves more clearly and honestly.
For those born under the zodiac sign of Pisces (which includes March 8th), aquamarine is thought to be particularly resonant. Pisces is known for its emotional depth, intuition, and empathy, and aquamarine is believed to help balance these sensitive traits, providing clarity and grounding. The stone's energy is seen as supportive, helping individuals born under this sign navigate their rich emotional landscape with greater serenity and wisdom.
Care and Cleaning
To maintain the beauty and integrity of an aquamarine gemstone, proper care and cleaning are essential. While its hardness of 7.5 to 8 on the Mohs scale makes it durable, it is still susceptible to damage if not handled correctly.
Cleaning: Aquamarine can be safely cleaned using warm, soapy water and a soft brush, such as a toothbrush. Gently scrub the stone and its setting to remove any dirt or oils that may have accumulated. Rinse thoroughly with clean water to ensure no soap residue remains. It is important to avoid harsh chemicals, such as bleach or ammonia, as these can damage the stone or the metal of its setting. While ultrasonic cleaners are generally safe for aquamarine, they should be used with caution. If the stone has any inclusions or fractures, the vibrations from the ultrasonic cleaner could potentially worsen them. Steam cleaning is also an option, provided the stone is free of significant inclusions.
Storage: When not being worn, aquamarine jewelry should be stored separately from other gemstones and jewelry pieces to prevent scratching. Although aquamarine is quite hard, it can be scratched by gems with a higher hardness, such as diamonds, sapphires, and rubies. It is best to keep aquamarine in a soft pouch or a lined compartment of a jewelry box to protect it from physical contact with other harder materials.
Handling and Wear: While aquamarine is suitable for everyday wear, it is wise to be mindful of activities that could pose a risk to the stone. It is advisable to remove aquamarine jewelry during tasks that involve heavy lifting, strenuous sports, or exposure to harsh environments. Protecting the gem from sharp blows and extreme temperature changes will help prevent accidental damage and ensure its longevity. Regular inspections of the jewelry's setting can also help identify any loose prongs or potential issues before they lead to the loss or damage of the stone.
