Aquamarine, the birthstone of March, is a gemstone renowned for its serene blue to blue-green hues, evoking the tranquil depths of the ocean. Its name, derived from the Latin words aqua (water) and marina (of the sea), is a fitting tribute to its visual allure and historical associations with the sea. As both a modern and traditional birthstone, aquamarine holds a unique place in the world of gemology, cherished for its beauty, durability, and rich symbolism. This article delves into the geological origins, historical significance, gemological properties, cultural symbolism, and practical care of aquamarine, drawing on a wealth of information from authoritative sources.
History and Lore
The history of aquamarine is deeply intertwined with the sea and its mythological significance. Ancient civilizations, particularly the Greeks and Romans, regarded aquamarine with reverence, associating it with Neptune, the god of the sea. According to legend, the gemstone was believed to be a treasure of the mermaids, and sailors carried it as a talisman for protection and good fortune during their voyages. This belief was rooted in the gem’s calming blue color, which was thought to mirror the serenity of the ocean.
During the medieval period, aquamarine was valued for its purported healing properties. Physicians used it to treat ailments of the throat, and it was also thought to soothe tempers and promote harmony. The gemstone was believed to have the power to calm an overactive mind and instill courage in the wearer. These qualities contributed to its reputation as a stone of tranquility and emotional balance.
Aquamarine also played a significant role in the realm of love and marriage. It was believed to bring happiness in marriage and was often gifted as a symbol of fidelity and harmony. In 1912, the National Association of Jewelers standardized the list of birthstones, and aquamarine was chosen as the modern birthstone for March, replacing the traditional bloodstone. This change was attributed to aquamarine's commercial appeal, transparency, and durability, making it more suitable for jewelry than the opaque bloodstone.
In addition to its role as a birthstone, aquamarine is also associated with the 19th wedding anniversary. This connection further emphasizes its symbolic value as a gemstone of enduring love and commitment.
Geological Formation and Sources
Aquamarine is a variety of beryl, a mineral family that also includes emerald and morganite. Its chemical composition is beryllium aluminum silicate (Be₃Al₂Si₆O₁₈), and its striking blue to blue-green color is due to trace amounts of iron in the crystal structure. This gemstone typically forms in pegmatites, which are coarse-grained igneous rocks. The formation process involves the slow cooling of magma, allowing the crystals to grow in size and clarity.
Aquamarine is found in various parts of the world, including Brazil, Pakistan, Madagascar, Nigeria, and the United States. Brazil, in particular, is known for producing high-quality aquamarine, with large, transparent crystals that are ideal for faceting. The gemstone's value is determined by the depth of its color and its clarity. Deeper blue hues are generally more desirable, as they are rarer and more visually striking.
Aquamarine belongs to the hexagonal crystal system and ranks between 7.5 and 8 on the Mohs scale of hardness. This high hardness makes it durable and suitable for everyday wear in jewelry. The gemstone is often cut into faceted gemstones, cabochons, or beads, depending on its intended use. Faceted aquamarines are prized for their brilliance and clarity, while cabochons are used to highlight the gem’s color and chatoyancy (a cat’s eye effect).
Gemological Properties
Aquamarine is a versatile gemstone with distinct physical and optical properties that contribute to its beauty and value. The following table summarizes the key gemological properties of aquamarine:
| Property | Description |

These properties make aquamarine a popular choice for a wide range of jewelry designs. Its high hardness and durability allow it to withstand daily wear, while its clarity and brilliance make it ideal for faceting. The gemstone's low dispersion means it does not exhibit the same fiery brilliance as diamonds or other high-dispersion gems, but its clean, even color and transparency are highly valued.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with calming energy, emotional healing, and spiritual clarity. Its soothing blue color is believed to evoke the tranquility of the ocean, promoting a sense of peace and serenity. In metaphysical practices, aquamarine is considered a stone of courage, helping individuals overcome fear and anxiety. It is also believed to enhance communication and self-expression, making it a powerful ally in personal and professional relationships.
One of the most notable metaphysical properties of aquamarine is its connection to the throat chakra. The throat chakra is associated with communication, truth, and self-expression. By aligning and activating this chakra, aquamarine is believed to help individuals speak their truth with confidence and clarity. It is also thought to promote honesty and integrity in communication, encouraging open and honest dialogue.
In addition to its chakra associations, aquamarine is believed to have protective qualities. It is considered a stone of protection for sailors, as it was believed to calm the seas and keep them safe during their voyages. This belief has carried over into modern times, with many people using aquamarine as a protective talisman for travel or challenging situations.
Aquamarine is also associated with emotional healing. It is believed to help individuals process and release emotional pain, particularly related to past traumas or difficult life transitions. This makes it a valuable tool in holistic wellness practices, where it is used to support emotional balance and inner peace.
Care and Cleaning
Due to its high hardness and durability, aquamarine is relatively easy to care for compared to other gemstones. However, it is important to follow proper cleaning and maintenance practices to ensure its longevity and beauty.
Aquamarine can be cleaned using warm, soapy water and a soft cloth or brush. Ultrasonic cleaners are generally safe for aquamarine, but caution should be exercised if the gemstone contains inclusions or fractures, as these can be exacerbated by the vibrations of the cleaner. Steam cleaning is not recommended, as the high heat and pressure can potentially damage the gemstone.
When storing aquamarine jewelry, it should be kept in a cool, dry place away from direct sunlight and other gemstones that may scratch its surface. It is best to store aquamarine in a soft pouch or a jewelry box with individual compartments to prevent it from coming into contact with harder gemstones such as diamonds or corundum.
Aquamarine should also be protected from harsh chemicals, including household cleaners, perfumes, and lotions. These substances can dull the gemstone’s luster and potentially damage its surface. When applying these products, it is advisable to remove aquamarine jewelry first and to wait until the products have been fully absorbed into the skin before reapplying the jewelry.
Cultural Significance and Modern Uses
In addition to its traditional and metaphysical significance, aquamarine has gained popularity in modern jewelry design and fashion. Its timeless blue color makes it a versatile gemstone that complements a wide range of styles and settings. Aquamarine is commonly used in pendants, earrings, rings, and bracelets, often paired with white gold, platinum, or silver to enhance its brilliance.
Aquamarine is also a popular choice for spring and summer fashion collections, as its light, refreshing color resonates with the season’s themes of renewal and vitality. Designers often incorporate aquamarine into their collections to add a touch of elegance and sophistication.
In the realm of holistic wellness, aquamarine is used in various forms, including raw crystals, palm stones, worry stones, and spheres. These forms are used for meditation, energy work, and emotional support. Raw aquamarine is believed to retain its natural energy, making it a powerful tool for grounding and centering.
The gemstone’s association with the throat chakra has also made it a popular choice for those seeking to enhance their communication and self-expression. It is often used in chakra healing practices to help individuals align and activate their throat chakra, promoting clarity and confidence in communication.
