Additionally, practical advice on caring for aquamarine jewelry will be provided, ensuring that this beautiful gemstone retains its luster and value for generations.
History and Lore
Aquamarine has been revered for centuries, particularly by seafaring cultures. Ancient sailors believed that the gemstone would protect them during long voyages and ensure safe passage across the seas. In fact, the gemstone was often carried on ships as a talisman, believed to ward off storms and bring calm waters. This association with the sea and protection is one of the reasons aquamarine has been linked to the month of March, which in the Roman calendar was originally the first month of the year, named after Mars, the god of war.
In ancient Egypt, aquamarine was considered a sacred stone and was used in amulets and jewelry. The Egyptians believed it had the power to bring clarity of thought and to aid in decision-making. Similarly, the Greeks and Romans attributed protective and calming properties to the gemstone. It was thought to enhance courage and provide mental clarity, making it a popular choice for those in positions of leadership or those facing important decisions.
Aquamarine’s historical significance extends beyond mythology and folklore. During the Renaissance, the gemstone became a symbol of nobility and purity. It was often used in royal regalia and was featured in the jewelry of European aristocracy. The gemstone’s popularity continued into the modern era, and today, it is one of the most sought-after birthstones, especially for those born in March.
Geological Formation and Sources
Aquamarine is a beryl, a mineral composed of beryllium aluminum silicate. Its chemical formula is Be₃Al₂(SiO₃)₆, and its blue color is caused by the presence of iron impurities within the crystal structure. The intensity of the blue color can vary, ranging from a pale, almost transparent blue to a deeper, more saturated hue. The most valuable and desirable aquamarine specimens are those with a medium to deep blue color and high clarity.
Aquamarine is formed in pegmatite rock formations, which are igneous rocks that cool slowly, allowing large crystals to develop. These formations are typically found in areas with high levels of beryllium and aluminum, such as in parts of South America, Africa, and the United States. Brazil is the most well-known source of aquamarine, with the gemstone being mined in states such as Minas Gerais and Bahia. Other notable sources include Nigeria, Zambia, and Madagascar.
The formation of aquamarine is a slow process that occurs deep within the Earth’s crust. As the pegmatite cools, the minerals within it begin to crystallize, and beryl, including aquamarine, can form. The presence of iron in the beryl structure gives the gemstone its characteristic blue color. The purity and clarity of the aquamarine depend on the conditions in which it was formed, with the finest specimens coming from environments that allowed for slow and even cooling.
Gemological Properties
Aquamarine is a durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This hardness makes it suitable for use in a variety of jewelry, including rings, necklaces, and earrings. However, like all gemstones, it is not impervious to damage. Aquamarine has a perfect cleavage in one direction, which means that it can be fractured if struck with sufficient force along that plane. Therefore, it is important to handle aquamarine jewelry with care, especially when it is set in rings or other pieces that are more likely to be subjected to impact.
In terms of optical properties, aquamarine has a refractive index of 1.56 to 1.58, which gives it a moderate level of brilliance. The gemstone is typically transparent to translucent and has a vitreous (glassy) luster. Its specific gravity is 2.67 to 2.83, which is relatively low compared to other gemstones, indicating that it is a light stone for its size.
Aquamarine is typically cut in a variety of styles, including the emerald cut, round brilliant cut, and oval cut. The emerald cut is particularly popular for aquamarine because it enhances the gemstone’s clarity and color. The cut is designed to maximize the stone’s brilliance while also showcasing its fine transparency.
When it comes to grading, the most important factors for aquamarine are color, clarity, and cut. The most valuable aquamarine stones are those with a deep, even blue color and minimal inclusions. Clarity is generally good, as aquamarine is a relatively clean gemstone, but inclusions are not uncommon and can add character to the stone. The cut is crucial for enhancing the gemstone’s beauty, as a well-cut aquamarine will display its color and brilliance to their fullest extent.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a range of symbolic and metaphysical properties. In addition to its historical use as a protective stone for sailors, the gemstone is believed to promote emotional balance, mental clarity, and inner peace. These qualities make it a popular choice for those seeking to reduce stress and anxiety, as well as for those looking to enhance their communication skills.
One of the most well-known associations with aquamarine is its connection to wisdom. The gemstone is believed to enhance the ability to think clearly and make sound decisions. This makes it particularly valuable for students, professionals, and anyone in a leadership position. Aquamarine is also thought to promote honesty and integrity, helping individuals to communicate more effectively and build trust in their relationships.
In addition to its cognitive and emotional benefits, aquamarine is believed to have physical healing properties. Some sources suggest that the gemstone can help to soothe the nervous system, reduce inflammation, and promote healthy skin. It is also thought to have a calming effect on the throat and respiratory system, making it a popular choice for those suffering from allergies or respiratory issues.
Aquamarine is also associated with the throat chakra, which is linked to communication and self-expression. Wearing aquamarine jewelry or meditating with the gemstone is believed to help open the throat chakra, allowing individuals to express themselves more freely and confidently. This makes it a particularly useful stone for public speakers, artists, and anyone who relies on effective communication as part of their work.
Care and Cleaning
Like all gemstones, aquamarine requires proper care to maintain its beauty and longevity. Because it has a perfect cleavage in one direction, it is important to avoid exposing aquamarine to sudden impacts or sharp blows. This is especially important when the gemstone is set in jewelry, as the setting can provide some protection, but it is still vulnerable to damage if not handled with care.
When it comes to cleaning aquamarine, it is best to use a soft cloth and a mild soap solution. A soft-bristled brush can be used to gently remove any dirt or debris from the surface of the gemstone. However, it is important to avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the gemstone or its setting. Additionally, aquamarine should be stored in a cool, dry place, away from direct sunlight and other gemstones that may scratch its surface.
Aquamarine is sensitive to high temperatures and prolonged exposure to strong light, which can cause it to lose its color over time. Therefore, it is advisable to avoid wearing aquamarine jewelry in direct sunlight for extended periods. If the gemstone appears to have lost its luster, it can be professionally cleaned and re-polished to restore its brilliance.
For those who wear aquamarine jewelry regularly, it is a good idea to have it inspected by a professional jeweler at least once a year. This will ensure that the setting is secure and that the gemstone is in good condition. Any signs of wear or damage should be addressed promptly to prevent further issues.

Aquamarine, the birthstone for those born on March 24, is a gemstone of remarkable beauty and significance. From its historical use as a protective talisman for sailors to its modern-day associations with wisdom, emotional balance, and communication, aquamarine has captivated people for centuries. Its geological properties, including its hardness, refractive index, and color, make it a durable and desirable gemstone for jewelry. Additionally, its metaphysical properties, which include calming effects and the promotion of clarity of thought, make it a valuable stone for both personal and spiritual use.
