History and Lore
Aquamarine’s history is as deep and storied as the ocean it resembles. References to this gemstone appear in the records of ancient civilizations, notably the Greeks and Romans, who were among the first to admire its oceanic hues. The very name aquamarine is a direct translation from the Latin aqua marina, meaning "water of the sea," a testament to its enduring association with the ocean and its calming properties.
In ancient times, aquamarine was believed to hold significant protective power, particularly for those who ventured upon the water. Ancient mariners carried the gem as a talisman, believing it could calm waves and ensure a safe passage across perilous seas. This belief in its protective qualities extended beyond the maritime realm. During the Medieval period, aquamarine was thought to possess a range of mystical properties. It was believed to reawaken the love of married couples and make the wearer unconquerable in battles and legal disputes. Furthermore, it was said to quicken the intellect and make the wearer amiable, suggesting a stone that not only protected the body but also enhanced the mind and spirit.
The transition of aquamarine from a talisman of protection to a symbol of personal attributes is evident in its modern associations. Today, it is revered for symbolizing courage, honesty, and loyalty. These qualities are seen as a natural extension of its historical lore, reflecting a stone that provides emotional stability and supports clear communication. Its adoption as the birthstone for March, and more specifically for the date of March 19th, solidifies its role as a gem that represents the intuitive and emotionally sensitive nature often attributed to those born in mid-March. The gem’s significance is further cemented by its role as the designated gift for the 19th wedding anniversary, linking its enduring beauty to the longevity of marriage.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, placing it in the same family as the renowned emerald. Its chemical formula is Be₃Al₂Si₆O₁₈, a structure that forms under specific geological conditions. Unlike emerald, which derives its green color from chromium or vanadium impurities, aquamarine’s distinctive blue and greenish-blue hues are the result of iron within its crystal lattice. The concentration of iron determines the intensity of the color, with higher levels typically producing deeper, more vivid blues.
The gemstone forms deep within the Earth's crust, specifically in granitic pegmatite rocks. These environments are characterized by the slow cooling of magma, which allows for the gradual growth of large, well-formed crystals. This slow crystallization process is why aquamarine is frequently found in larger sizes compared to many other gemstones. The pegmatite environment also contributes to the gem’s hallmark clarity; high-quality aquamarine often exhibits excellent transparency and a vitreous luster, with few inclusions.
Aquamarine is mined in various locations across the globe, reflecting its widespread geological occurrence. Significant sources include Brazil, China, Kenya, Madagascar, Mozambique, Nigeria, Pakistan, and Zambia. Brazil, in particular, has been a notable source, historically presenting large specimens to notable figures. For example, in 1936, the government of Brazil gifted First Lady Eleanor Roosevelt a dark blue, rectangular step-cut aquamarine weighing 1,298 carats. The largest cut aquamarine in the world is the Dom Pedro, which weighs approximately 10,363 carats (about 4.6 pounds), showcasing the gem’s potential for impressive size. An interesting gemological property noted in the sources is that aquamarine’s color typically becomes more intense with larger stones, a characteristic that is unusual among gemstones.
Gemological Properties
Understanding the physical and optical characteristics of aquamarine is essential for its identification and appreciation. As a member of the beryl family, it shares several properties with its cousins but possesses unique traits that distinguish it.
Color: Aquamarine’s color ranges from light, slightly greenish-blue to deep blue. The most prized specimens exhibit a deep, intense blue, though most aquamarines on the market today are a lighter blue. The color is caused by iron impurities in the crystal structure.
Clarity and Luster: One of aquamarine’s most valued attributes is its excellent clarity. Faceted aquamarines are often free from inclusions, appearing as clear as water, which symbolizes purity of spirit and soul. This transparency gives the gem a brilliant vitreous luster when properly cut.
Hardness and Durability: On the Mohs scale of mineral hardness, beryl, including aquamarine, ranks between 7.5 and 8. This makes it a relatively durable gemstone, suitable for all types of jewelry, including rings that are subject to daily wear. Its hardness contributes to its ability to maintain a high polish and resist scratching.
Crystal System and Form: Aquamarine crystallizes in the hexagonal system. Its formation in pegmatites often results in well-formed, prismatic crystals that can be cut into a variety of faceted shapes, such as emerald cuts, oval cuts, and pear cuts, to best display its color and clarity.
Cut and Carat: The gem’s clarity and size allow for versatile cutting styles. Large, clean crystals are often fashioned into statement pieces, while smaller, lighter-colored stones are commonly used in delicate jewelry. The Dom Pedro, as mentioned, is a testament to the gem’s ability to be cut into massive, impressive carat weights.

Care and Cleaning
Given its gemological properties, aquamarine is a durable stone that can be worn daily with proper care. Its hardness (7.5 to 8 on the Mohs scale) makes it resistant to scratching from everyday materials, but it is not indestructible. To maintain its brilliance and ensure its longevity, follow these guidelines for cleaning and storage.
Cleaning: Aquamarine can be safely cleaned using warm water, a mild soap, and a soft brush. Avoid using harsh chemicals, such as bleach or ammonia, as they can damage the stone or its setting. Ultrasonic cleaners are generally safe for aquamarine, provided the stone is not fractured. However, steam cleaning is not recommended, as sudden temperature changes can potentially cause damage, especially if the gem has inclusions. After cleaning, rinse the gem thoroughly to remove any soap residue and dry it with a soft, lint-free cloth.
Storage: When not in use, store aquamarine jewelry separately from other pieces to prevent scratches. A soft pouch or a lined jewelry box is ideal. Given its clarity and value, it is advisable to keep it away from direct sunlight for prolonged periods, as intense light and heat could potentially affect some colored gemstones over time, though aquamarine is generally stable.
Handling: While aquamarine is suitable for rings, earrings, and pendants, it is still a gemstone that can be chipped or cracked if struck with sufficient force. Avoid wearing aquamarine jewelry during heavy physical activities, such as gardening or sports, where it might be subject to impact.
By following these simple care instructions, owners of aquamarine can preserve the stone’s stunning blue color, exceptional clarity, and overall beauty for a lifetime.
