Aquamarine, a gemstone celebrated for its serene blue hues, is the recognized birthstone for March. Revered for millennia, this variety of beryl holds a prominent place in history, lore, and the modern jewelry market. Its name, derived from the Latin words for seawater, aptly reflects its captivating color and enduring association with the ocean. This article will delve into the history, geological origins, gemological properties, symbolism, and care of aquamarine, drawing exclusively from available sources.
History and Lore
The history of aquamarine is deeply intertwined with maritime traditions and beliefs in its protective powers. Ancient mariners believed the gem possessed the ability to calm waves and ensure safe passage, making it a cherished talisman for sailors. Beyond seafaring, aquamarine was thought to bring happiness in marriage and offer protection against foes in battle and legal disputes. Sources indicate that beryl, the mineral family to which aquamarine belongs, was believed to make the wearer unconquerable and amiable, while also quickening the intellect.
The gemstone’s association with fidelity and enduring love has led to its traditional use in commemorating the 19th wedding anniversary. This practice underscores the stone’s symbolic connection to lasting relationships and emotional well-being. Folklore further designates aquamarine as the “treasure of the mermaids,” adding to its mystique and allure. Throughout history, it has been utilized in prayer and meditation, signifying its spiritual significance.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, closely related to the emerald. It forms in pegmatite deposits, which are coarse-grained igneous rocks. These deposits are found in both primary (hard rock) and secondary (weathered) formations.
Brazil, specifically the state of Minas Gerais, has been a significant source of aquamarine for over two centuries. The region’s diverse landscape, encompassing rocky hills, rivers, savannahs, and forests, harbors these valuable gem deposits. Other notable locations include Sri Lanka, Pakistan, Colorado, and Idaho. The Brazilian deposits near the gem center of Teófilo Otoni are particularly well-known for their aquamarine production.
Gemological Properties
Aquamarine’s defining characteristic is its color, ranging from a pale pastel blue to a greenish-blue, and occasionally a deeper, more saturated blue. The striking blue hue is attributed to the presence of iron within the crystal structure. It is important to note that aquamarine generally exhibits lighter tones and saturations compared to other blue gemstones like sapphire. Larger aquamarines often display more intense color, while smaller stones tend to be less vivid.
As a variety of beryl, aquamarine shares similar physical properties with its counterparts. It is an inherently light crystal. While specific data regarding hardness and refractive index are not provided in the sources, it is understood to be a durable gemstone suitable for various jewelry applications.
Notable examples of exceptional aquamarine specimens include the 1,298-carat dark blue rectangular step-cut stone presented to First Lady Eleanor Roosevelt by the Brazilian government in 1936, now housed at the Franklin D. Roosevelt Presidential Library and Museum. The Smithsonian Institution boasts the Dom Pedro Aquamarine, a 10,363-carat obelisk fashioned using the fantasy cut technique by Berndt Munsteiner, and believed to be the largest faceted aquamarine in the world.

Symbolism and Metaphysical Beliefs
Beyond its aesthetic appeal, aquamarine carries significant symbolic weight. Its name, meaning “seawater,” evokes themes of tranquility, clarity, and emotional healing. Some believe aquamarine possesses restorative properties, rejuvenating both the body and mind. It is thought to lift spirits, promote clear thinking, and offer provision and good luck.
Metaphysical practitioners associate aquamarine with aiding in legal matters and litigation, potentially stemming from its historical connection to protection and favorable outcomes. Energy healers consider bloodstone, an alternative March birthstone, to possess strong healing powers, increasing mental and emotional strength and energy, and aligning with the lower chakras. However, the sources primarily focus on the symbolism and metaphysical properties of aquamarine itself.
Care and Cleaning
While the sources do not provide detailed care instructions, aquamarine’s relative durability suggests it can be maintained with standard gemstone care practices. Given its hardness, it is generally resistant to scratching from everyday wear. Routine cleaning with warm, soapy water and a soft brush is recommended to remove dirt and oils. As with any gemstone, avoid harsh chemicals, ultrasonic cleaners, and extreme temperature fluctuations.
Conclusion
Aquamarine stands as a captivating gemstone, steeped in history, symbolism, and natural beauty. From its ancient origins as a talisman for sailors to its modern recognition as the March birthstone and a symbol of enduring love, aquamarine continues to enchant and inspire. Its serene blue hues, coupled with its association with tranquility and clarity, make it a cherished gem for jewelry enthusiasts and a meaningful gift for those born in the third month of the year. The gemstone’s geological origins in Brazil and other locations around the world, combined with its unique gemological properties, solidify its position as a treasure of the sea and a testament to the wonders of the natural world.
