Introduction
Aquamarine, a member of the beryl family, is the designated birthstone for March 8th and the entire month of March. Its name derives from the Latin words aqua (water) and mare (sea), reflecting its resemblance to the colors of the ocean. Beyond its aesthetic appeal, aquamarine has been revered across cultures and epochs for its purported ability to enhance mental clarity, promote emotional balance, and offer protection. This article explores the gemstone’s geological properties, historical and cultural significance, and its role in modern jewelry and spiritual practices. We also consider its care and preservation, ensuring that aquamarine remains a cherished possession for generations.
History and Lore
Aquamarine has a rich and enduring legacy that spans thousands of years. Ancient civilizations, from the Greeks and Romans to the Incas and Europeans, held aquamarine in high regard, attributing to it a range of mystical properties and practical uses.
Ancient Beliefs and Traditions
One of the earliest recorded references to aquamarine is from the Roman naturalist Pliny the Elder, who described it as a protective stone for sailors. It was believed that aquamarine could calm the seas and ensure safe passage for those at sea. This belief was rooted in the stone’s oceanic appearance and was passed down through generations of maritime cultures.
In medieval Europe, aquamarine was thought to be a powerful talisman for those in positions of authority. It was often worn by kings and nobility to inspire courage and wisdom. During the Renaissance, aquamarine became a symbol of purity and spiritual enlightenment, frequently incorporated into religious artifacts and royal regalia.
March and Its Symbolism
The month of March holds special significance in many cultures as a time of renewal and rebirth. As the first month of the spring season in the Northern Hemisphere, March is often associated with fresh beginnings, growth, and hope. This symbolism is reflected in the March birthstones—both aquamarine and bloodstone—which are believed to support the transition from winter to spring by promoting vitality and resilience.
March is also the month in which International Women’s Day is celebrated on March 8th. While this observance is a modern phenomenon, it aligns with the historical role of aquamarine as a protective and empowering stone. The gemstone’s connection to wisdom and confidence makes it a fitting symbol for those who have contributed to the advancement of women’s rights and social justice.
Cultural and Spiritual Significance
Across various cultures, aquamarine has been associated with a wide range of spiritual and metaphysical properties. In Hindu tradition, aquamarine is linked to the throat chakra and is believed to enhance communication and self-expression. In Chinese culture, it is considered a stone of serenity and is often used in feng shui practices to promote harmony and balance.
Modern holistic practitioners continue to regard aquamarine as a powerful stone for emotional healing. It is said to help individuals overcome fears, especially those related to public speaking or social interactions. Some also believe that aquamarine can aid in sleep and reduce anxiety, making it a popular choice for meditation and relaxation practices.
Geological Formation and Sources
Aquamarine is a variety of beryl, a mineral composed of beryllium aluminum silicate. It is formed in igneous and metamorphic rock environments, often in association with granite and pegmatite deposits. The gemstone’s distinctive blue color is due to the presence of iron impurities within the crystal lattice. The intensity of the blue hue can vary depending on the concentration of these impurities, with the most valuable specimens displaying a vivid, sky-blue color.
Formation Process
The formation of aquamarine involves a slow, complex process that takes place deep within the Earth’s crust. As molten rock cools and solidifies, beryllium and aluminum combine with silica to form beryl crystals. When trace amounts of iron are present, the crystals develop the blue color characteristic of aquamarine. These conditions are rare, which is why aquamarine is considered a relatively rare gemstone compared to other birthstones.
Major Sources
Aquamarine is found in several parts of the world, with the most notable sources including:
Brazil: Brazil is the largest and most well-known source of aquamarine. The gemstone is often found in the pegmatite deposits of Minas Gerais, where large, high-quality crystals are mined. Brazilian aquamarine is prized for its clarity and vibrant color.
Colombia: Colombia is another major source of aquamarine. The gemstone is often found in association with emeralds, which are also beryls. Colombian aquamarine tends to have a lighter, more delicate blue color compared to its Brazilian counterpart.
Nigeria: Nigeria is a growing source of aquamarine, producing gemstones that are typically smaller in size but of high quality.
Madagascar, Afghanistan, and the United States: These countries also produce aquamarine, though in smaller quantities. African and Central Asian sources often yield stones with a greener tint, while American aquamarine is less common but can be found in states like California and New Mexico.
Gemological Properties
Aquamarine is a durable and versatile gemstone, making it a popular choice for jewelry. Its unique combination of hardness, clarity, and color ensures that it can be cut and polished into a variety of styles, from classic faceted cuts to cabochons and beads.

Color Variability and Pleochroism
One of the most intriguing characteristics of aquamarine is its pleochroism—the ability to display different colors when viewed from different angles. This means that an aquamarine crystal may appear blue from one angle and green from another. This property is particularly noticeable in unheated stones and can affect the way a gemstone is cut and set in jewelry.
Historically, aquamarine with a greenish tint was considered more valuable than the modern sky-blue varieties. However, with the rise of market demand for vibrant blue hues, today’s most sought-after aquamarine stones are those with a pure, vivid blue color.
Clarity and Inclusions
Aquamarine is generally a clean gemstone with few inclusions, especially when compared to other beryls like emerald. Most aquamarine specimens are free from visible flaws and can be graded as "eye-clean." When inclusions are present, they are often small gas bubbles or rutile needles that do not detract from the stone’s beauty or durability.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a range of metaphysical and symbolic meanings. These beliefs have evolved over time but continue to influence how the gemstone is perceived in modern contexts.
Ancient Symbolism
In ancient times, aquamarine was believed to possess protective and calming properties. Sailors carried it for safe passage across the seas, and rulers wore it to gain wisdom and strength. The gemstone was also used in mourning jewelry, symbolizing the grief of the sea and the tears of lovers.
Modern Metaphysical Properties
Today, aquamarine is regarded as a stone of serenity, courage, and emotional healing. It is often used in crystal healing and meditation to promote inner peace and self-confidence. Some of the key metaphysical properties attributed to aquamarine include:
Emotional Balance: Aquamarine is believed to soothe the mind and reduce anxiety, making it a valuable tool for those dealing with stress or emotional turmoil.

Given its durability and hardness, aquamarine is relatively easy to care for compared to other gemstones. However, it is still important to handle it with care to maintain its beauty and longevity.
Recommended Care Practices
Cleaning: Aquamarine can be cleaned using warm, soapy water and a soft cloth or brush. Ultrasonic and steam cleaners are generally safe for aquamarine, though caution should be taken if the stone has any inclusions or is set in a delicate design.
Storage: Store aquamarine away from harder gemstones to prevent scratches. A soft pouch or separate compartment in a jewelry box is ideal.
Avoiding Damage: While aquamarine is relatively tough, it can be damaged by exposure to harsh chemicals, extreme temperatures, or physical impact. It is best to avoid wearing aquamarine jewelry during activities that may subject it to abrasion or heat.
Refractive Stability: Aquamarine is stable under normal lighting conditions and does not fade over time. However, prolonged exposure to direct sunlight or artificial light may cause the color to dull slightly.
