History and Lore
Aquamarine has a long and fascinating history, with roots stretching back to ancient civilizations. The Egyptians, Greeks, and Romans all associated the stone with the sea and its deities. Ancient mariners believed that aquamarine could calm the waves and protect sailors on their journeys. In Roman mythology, the stone was believed to be a gift from the sea gods, and it was often carried by sailors for protection against storms and shipwrecks.
In addition to its maritime associations, aquamarine has been linked to courage, clarity, and emotional balance. It was believed to bring happiness in marriage and to quicken the intellect, making it a gemstone of both personal and spiritual significance. The stone was also considered a powerful talisman in battle and litigation, as it was thought to grant the wearer protection against foes and the strength to remain amicable and unconquerable.
Beyond its ancient uses, aquamarine has also found a place in modern traditions. It is traditionally given as a gift to celebrate a 19th wedding anniversary, symbolizing enduring love and happiness. In 1936, the government of Brazil gifted a 1,298-carat aquamarine to First Lady Eleanor Roosevelt, highlighting the gemstone’s prestige and value.
Geological Formation and Sources
Aquamarine is a member of the beryl family, a mineral group that also includes emerald. Chemically, beryl is composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆), with the blue coloration of aquamarine resulting from trace amounts of ferrous iron (Fe²⁺). The gemstone forms in igneous rocks, particularly in granite pegmatites and metamorphic rocks, where it crystallizes under high-temperature and low-pressure conditions.
The formation of aquamarine involves the slow cooling of molten rock, which allows the mineral to grow in large, well-formed crystals. These crystals are then exposed at the Earth’s surface through geological processes such as erosion, where they can be mined. The most notable sources of aquamarine include Brazil, Nigeria, Zambia, and Madagascar. Brazil, in particular, is renowned for producing large, high-quality aquamarine crystals, some of which weigh several kilograms.
Aquamarine is typically found in a range of blue tones, from light blue-green to deep blue. The most valuable specimens are those with a rich, even color and high clarity. Because of its formation in geological environments with minimal impurities, aquamarine is often free from inclusions, giving it a clear, glass-like appearance. This clarity, combined with its vibrant color, makes aquamarine a highly sought-after gemstone in the jewelry industry.
Gemological Properties
Aquamarine is a durable gemstone with a hardness of 7.5 to 8 on the Mohs scale, making it suitable for everyday wear. Its refractive index ranges from 1.56 to 1.58, which contributes to its brilliance and luster. The gemstone is typically transparent to translucent, and its specific gravity is approximately 2.67 to 2.83, which is relatively light for a silicate mineral.
One of the key characteristics of aquamarine is its pleochroism—the ability to show different colors when viewed from different angles. In aquamarine, this means that the gemstone may appear slightly greenish when viewed along one axis and more blue when viewed along another. This property is more pronounced in lighter-colored specimens and can affect the way the gemstone is cut and polished.
Aquamarine is often cut in a brilliant or step-cut style to maximize its clarity and color. Because it is relatively free from inclusions, it is well-suited for these cuts, which emphasize the gemstone’s transparency and sparkle. The most popular cuts for aquamarine include the emerald cut, round brilliant cut, and princess cut.
In terms of carat weight, aquamarine can be found in a wide range of sizes, from small gemstones used in earrings and pendants to larger stones used in rings and brooches. The largest known aquamarine, the 1,298-carat specimen gifted to Eleanor Roosevelt, is a testament to the gemstone’s potential for size and beauty.
Symbolism and Metaphysical Beliefs
Aquamarine is rich in symbolism and has been associated with a wide range of metaphysical beliefs across different cultures and time periods. Its calming blue color is often linked to the sea, and it is believed to bring peace, balance, and emotional stability to its wearer. In ancient times, aquamarine was considered a powerful talisman for sailors, who believed it would protect them from the dangers of the sea and ensure safe passage.
In addition to its maritime associations, aquamarine is also believed to promote courage and clarity. It is often associated with the throat chakra, which is the energy center in the body responsible for communication. As a result, aquamarine is thought to enhance one’s ability to express themselves clearly and honestly, making it a popular gemstone for those in professions that require public speaking or communication.
Aquamarine is also believed to have healing properties, particularly in relation to the throat and respiratory system. Some sources suggest that it can help soothe the throat and support healthy breathing, making it a valuable gemstone for those with vocal or respiratory issues. It is also associated with the calming of the mind and the reduction of stress and anxiety, making it a popular choice for those seeking emotional balance and inner peace.
In modern metaphysical practices, aquamarine is often used in meditation and energy work. It is believed to help the wearer connect with the divine and access higher states of consciousness. Its gentle, calming energy is thought to create a sense of harmony and tranquility, making it an ideal gemstone for those seeking spiritual growth and emotional healing.
Care and Cleaning
Because of its durability and hardness, aquamarine is a relatively easy gemstone to care for. However, like all gemstones, it requires proper cleaning and handling to maintain its beauty and longevity. Aquamarine can be cleaned using a mild soap and warm water solution, as well as a soft brush or cloth. It is important to avoid harsh chemicals, as these can damage the gemstone’s surface and affect its clarity.
Aquamarine can be safely exposed to ultrasonic and steam cleaners, which are effective at removing dirt and grime without causing damage to the gemstone. However, it is important to note that aquamarine is not heat-sensitive, but prolonged exposure to high temperatures can cause it to lose its color or become brittle.
When storing aquamarine jewelry, it is best to keep it in a soft cloth or a jewelry box to prevent scratches and damage. Because aquamarine can be dented or cracked if struck with a hard object, it is important to avoid wearing it during activities that involve physical contact or impact.
For daily wear, aquamarine is an excellent choice because of its durability and resistance to wear. However, it is important to be mindful of the environments in which the gemstone is worn, as exposure to harsh chemicals, extreme temperatures, and physical impacts can all affect its appearance and integrity.
