Aquamarine, the captivating blue gemstone associated with the month of March, carries a legacy of maritime protection, intellectual clarity, and emotional serenity.

This article explores the origins, symbolism, geological formation, and practical care of aquamarine, offering a comprehensive overview for gemstone enthusiasts, jewelry collectors, and those curious about the cultural and scientific aspects of this radiant stone.
Aquamarine’s name is derived from the Latin words aqua, meaning water, and mare, meaning sea, reflecting its deep connection to the ocean and its soothing blue hues. The March birthstone has long been associated with calmness, purity, and hope, making it a popular choice for those born in the springtime month. In addition to its role as a birthstone, aquamarine is also the gift for the 19th wedding anniversary, symbolizing enduring love and clarity of purpose.
This article will explore aquamarine’s historical use in ancient cultures, its geological properties, its symbolic significance across different societies, and how to care for and maintain its beauty over time. We will also touch upon its role as one of two March birthstones, alongside bloodstone, and how both gems contribute to the month’s rich gemstone heritage.
History and Lore
Aquamarine’s history is deeply intertwined with maritime traditions and ancient beliefs. In the ancient world, seafarers believed the gemstone could protect them from the dangers of the sea. This belief is rooted in its name, which reflects its association with seawater. Sailors carried aquamarine to calm stormy waters and ensure safe passage, believing that the gem had the power to ward off tempests and keep the sea at peace.
Beyond its maritime associations, aquamarine was also believed to bring happiness and harmony in relationships. In ancient times, it was considered a symbol of fidelity and was often given as a gift to promote love and unity. The gemstone was also linked to intellectual and emotional clarity, with some believing that it could enhance one’s ability to think clearly and make sound decisions.
In medieval Europe, aquamarine was part of a broader tradition of protective gemstones used in rings and amulets. It was thought to offer the wearer protection in battle and litigation, making it a favored stone among warriors and those engaged in legal disputes. The gem was also believed to make the wearer amiable and unconquerable, further emphasizing its role as a symbol of strength and resilience.
Aquamarine’s historical significance was not limited to Europe. In Brazil, where some of the finest aquamarine deposits are found, the gem has played a key role in local culture and commerce. Brazilian artisans have long used aquamarine in jewelry, and the country has become a leading source of high-quality specimens.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which has the chemical formula Be₃Al₂(SiO₃)₆. It gets its blue color from trace amounts of iron within its crystal structure. The intensity of the blue hue varies depending on the concentration of iron and other impurities, resulting in a range of colors from pale blue to deep cobalt blue.
Aquamarine typically forms in pegmatite deposits, which are igneous rocks that cool slowly and allow large crystals to develop. These deposits are rich in minerals and are often found in areas with a history of volcanic activity. The Brazilian state of Minas Gerais is one of the most important sources of aquamarine in the world. The region has been a major supplier of the gem for centuries, and its aquamarine is known for its clarity and vibrant color.
In addition to Brazil, aquamarine is also found in other parts of the world, including Nigeria, Madagascar, Pakistan, and the United States. Each location produces aquamarine with slightly different characteristics, but the most prized specimens tend to come from Brazil due to their exceptional color and clarity.
Aquamarine can be found in both primary and secondary deposits. Primary deposits are found in the original rock formations where the gemstone was created, while secondary deposits are found in alluvial deposits, where the gemstone has been eroded and transported by water. The secondary deposits often yield high-quality aquamarine that has been naturally polished by river currents.
Aquamarine is typically cut into faceted stones to showcase its brilliance and color. However, some specimens are cut as cabochons, especially when they have inclusions or other features that are best displayed in a smooth, rounded shape.
Gemological Properties
Aquamarine is a relatively hard gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This makes it durable enough for everyday wear, although it is not as hard as diamonds or sapphires. Its hardness allows it to be cut into a variety of shapes and styles, making it a versatile choice for jewelry.
The gemstone has a refractive index of 1.577 to 1.583 and a specific gravity of 2.67 to 2.80. These properties help distinguish aquamarine from other blue gemstones, such as blue topaz or sapphire. Aquamarine is also typically free of inclusions, which contributes to its clarity and makes it appear as clear as water.
One of the most distinctive features of aquamarine is its color. The blue color ranges from a pale, almost transparent blue to a deep, intense cobalt blue. The most valuable specimens are those with a vivid blue color and high clarity. Aquamarine can also have a slight greenish tint, especially when viewed under certain lighting conditions.
Aquamarine is often heat-treated to enhance its color. In its natural state, some aquamarine may have a more greenish or yellowish hue, but heating it to around 400°C can transform it into a more vibrant blue. This treatment is widely accepted in the gemstone industry and does not affect the stone’s durability or value.
Aquamarine is also known for its pleochroism, meaning it can display different colors when viewed from different angles. This effect is most noticeable in larger stones and can add to the gem’s visual interest.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with calmness, clarity, and emotional balance. In ancient times, it was believed to have the power to soothe the mind and promote mental clarity. This belief persists in modern times, with many people attributing calming and centering properties to the gemstone.
In metaphysical traditions, aquamarine is associated with the throat chakra, which is linked to communication and self-expression. It is believed to help individuals speak their truth with confidence and clarity. This makes it a popular stone for those who work in fields that require public speaking or communication.
Aquamarine is also believed to promote courage and strength. Its association with the sea and the idea of navigating life’s challenges has made it a symbol of resilience. Those who wear aquamarine are thought to be more confident in facing difficult situations and are believed to be protected from negative energies.
The gemstone is also associated with emotional healing. It is believed to help individuals process emotions and move on from past traumas. Its calming properties make it a popular choice for those seeking emotional balance and inner peace.
In addition to its emotional benefits, aquamarine is also associated with physical health. In the past, it was used to treat ailments of the heart, liver, and stomach. While these claims are not supported by modern medicine, the gemstone continues to be valued for its symbolic and spiritual significance.
Care and Cleaning
Because aquamarine has a relatively high hardness on the Mohs scale, it is suitable for everyday wear. However, it can still be scratched or damaged if not cared for properly. To keep aquamarine jewelry looking its best, it should be stored separately from other gemstones to prevent scratches.
Aquamarine can be cleaned with warm, soapy water and a soft brush. It should be rinsed thoroughly and dried with a soft cloth. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone’s surface or remove any treatments that have been applied.
When storing aquamarine jewelry, it is best to wrap it in a soft cloth or place it in a separate compartment to prevent contact with other jewelry. This will help maintain its clarity and luster over time.
Aquamarine is also sensitive to extreme heat, so it should be removed before exposing it to high temperatures, such as when using a sauna or hot tub. Prolonged exposure to direct sunlight or artificial heat can cause the color to fade or become discolored.
Aquamarine is a versatile gemstone that can be worn in a variety of settings. Its hardness and durability make it suitable for rings, necklaces, and earrings. When designing aquamarine jewelry, it is important to consider the setting and the other gemstones that will be used. Because aquamarine has a relatively high refractive index, it pairs well with diamonds and other clear gemstones.
