History and Lore of Aquamarine
Aquamarine has a long and storied history that dates back to ancient civilizations. In antiquity, it was believed to be the treasure of mermaids and was often carried by sailors for protection and good fortune at sea. Ancient sailors and navigators regarded Aquamarine as a talisman that could calm the waves and safeguard them from the dangers of the ocean. This belief is reflected in the gemstone’s name and its association with the sea.
The ancient Egyptians and Romans were among the first to use Aquamarine in jewelry, often setting it in rings as a protective talisman. During the medieval period, Aquamarine was thought to possess healing properties and was used in various forms of traditional medicine. It was also believed to promote courage and clarity of thought, making it a favored gemstone for warriors and leaders.
In more modern times, Aquamarine continued to be valued for its beauty and symbolism. It became a popular choice for jewelry in the Victorian era and has remained a favorite in the 20th and 21st centuries. One notable example is the large aquamarine presented to First Lady Eleanor Roosevelt in 1936 by the government of Brazil. This gemstone, weighing 1,298 carats and cut in a rectangular step style, is a testament to the gem’s grandeur and significance.
Aquamarine’s association with calmness and protection extends beyond its historical use. Today, it is often given as a meaningful gift, particularly on the 19th wedding anniversary. The gemstone’s symbolism of serenity and strength makes it a fitting choice for those seeking to convey peace, clarity, and enduring love.
Geological Formation and Sources of Aquamarine
Aquamarine is formed through geological processes that occur deep within the Earth’s crust. As a member of the beryl family, it is a beryllium aluminum silicate mineral. The gemstone’s characteristic blue-green color is due to the presence of trace amounts of iron in the crystal structure. The exact shade of blue can vary depending on the concentration of iron and the conditions under which the crystal formed.
Aquamarine is typically found in granitic pegmatites and metamorphic rocks, where it forms in a high-temperature environment. These conditions allow the gemstone to develop its clear, transparent quality and vibrant color. The formation process can take millions of years, during which time the crystal grows slowly and steadily.
The primary sources of Aquamarine are located in several countries across the globe. Brazil is one of the most significant producers of high-quality Aquamarine, particularly in the states of Minas Gerais, Bahia, and Espírito Santo. These regions are known for their large, well-formed crystals that are often cut into faceted gemstones. Other notable sources include Colombia, Zambia, Madagascar, Nigeria, and the United States.
The mining of Aquamarine is often done through open-pit or underground methods, depending on the location of the deposit. Once extracted, the rough stones are cut and polished to enhance their natural beauty. The most valuable Aquamarines are those with a deep blue color and excellent clarity, as these traits make the gemstone particularly desirable in the jewelry market.
Gemological Properties of Aquamarine
Aquamarine possesses a range of gemological properties that contribute to its popularity and durability as a gemstone. Its chemical formula is Be₃Al₂(SiO₃)₆, and it belongs to the hexagonal crystal system. The gemstone has a refractive index that typically ranges from 1.56 to 1.60, which gives it a moderate level of brilliance when cut properly.
One of the most notable characteristics of Aquamarine is its hardness, which is rated at 7.5 to 8 on the Mohs scale. This level of hardness makes it suitable for use in a variety of jewelry pieces, including rings, which are often subjected to daily wear and potential impacts. However, despite its hardness, Aquamarine can still be damaged if exposed to hard knocks or abrasion, so care should be taken when handling and wearing Aquamarine jewelry.
Aquamarine is also known for its excellent transparency and lack of inclusions in many high-quality stones. This clarity enhances the gemstone’s brilliance and makes it particularly desirable for use in fine jewelry. The absence of inclusions also allows for a wide range of cutting styles, from classic round and oval cuts to more elaborate shapes such as emerald cuts and pear-shaped cuts.
In terms of color, Aquamarine is most prized for its vivid blue hues. The most valuable stones have a deep blue color with a slight greenish undertone, often referred to as "blue-green." Pale blue stones are also available, but they are generally less valuable than their deeper-colored counterparts. The intensity of the color can be enhanced through heat treatment, a common practice in the gemstone industry to improve the appearance of Aquamarine.

Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a range of symbolic meanings and metaphysical properties. In many cultures, it is regarded as a stone of calm and serenity, believed to promote emotional balance and mental clarity. This belief is rooted in its connection to the sea, which has long been seen as a symbol of tranquility and the unknown.

Ancient mariners believed that carrying an Aquamarine would protect them from the dangers of the ocean and ensure a safe journey. This belief is reflected in the gemstone’s name and its historical use in maritime cultures. Even today, Aquamarine is sometimes worn by sailors and those who travel by sea as a symbol of protection and good fortune.
In addition to its protective qualities, Aquamarine is also associated with courage and strength. It was believed that the gemstone could enhance the bravery of warriors and leaders, making it a popular choice for those in positions of power. This association with courage is thought to stem from the gemstone’s deep blue color, which is often linked to the vastness of the sea and the strength of the human spirit.

Care and Cleaning of Aquamarine
Due to its relatively high hardness and durability, Aquamarine is a gemstone that can be enjoyed in a variety of jewelry settings. However, like all gemstones, it requires proper care and maintenance to preserve its beauty and longevity. Aquamarine is generally safe to clean with standard jewelry cleaning methods, but there are a few considerations to keep in mind.
To clean Aquamarine jewelry, it is recommended to use a soft, lint-free cloth and a mild soap or a commercial jewelry cleaner. The gemstone should be gently wiped to remove any dirt or oils that may have accumulated on its surface. For more thorough cleaning, Aquamarine can be soaked in a solution of warm water and mild detergent for a few minutes, then rinsed and dried with a soft cloth.
It is important to avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners when cleaning Aquamarine. These methods can potentially damage the gemstone, especially if it has been treated to enhance its color. Ultrasonic cleaners, in particular, can cause damage to the internal structure of the stone, leading to fractures or other imperfections.
When storing Aquamarine jewelry, it is best to keep it in a soft pouch or a separate compartment to prevent scratches from other gemstones or metals. Aquamarine should also be kept away from direct sunlight and extreme temperatures, as these can cause the gemstone to fade or become brittle over time.
In terms of wear, Aquamarine is a durable gemstone that can withstand daily use in most jewelry pieces. However, it should still be handled with care to avoid impacts or abrasions that could cause chips or fractures. Rings with Aquamarine should be avoided if the gemstone is set in a way that leaves it vulnerable to damage, such as in a claw setting that exposes the edges of the stone.
