History and Lore
Aquamarine has a storied history that spans centuries, with its name and symbolism deeply rooted in maritime tradition. Ancient mariners believed that aquamarine could calm the waves and ensure safe passage across the seas. This belief was not unfounded in the cultural context of the time, as many ancient civilizations attributed protective qualities to gemstones. The gem was also thought to bring happiness in marriage and to offer protection in battle and litigation. In some traditions, it was believed that aquamarine made the wearer unconquerable and amiable, while also quickening the intellect.
The gemstone’s association with the sea is not only reflected in its name but also in its historical use as a talisman for sailors. This maritime symbolism persists today, with many still believing in aquamarine’s ability to protect travelers and bring calm in times of stress.
Beyond its maritime lore, aquamarine also has a notable place in the history of jewelry. As the birthstone for March, it has been a popular choice for rings, earrings, and pendants. Its elegant blue hues make it a versatile gemstone that complements a wide range of jewelry designs. Aquamarine is also given as a gift to commemorate the 19th wedding anniversary, adding to its significance in personal and cultural traditions.
One of the most famous aquamarine gemstones in history is a 1,298-carat rectangular step-cut stone that was gifted to Eleanor Roosevelt in 1936 by the government of Brazil. This remarkable specimen is a testament to the gemstone’s rarity and value, particularly when it exhibits deep blue coloration and high clarity.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which is composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆). The gemstone's blue coloration is due to the presence of iron impurities within the crystal structure. Aquamarine is typically found in granite pegmatites and in the veins of metamorphic rocks that have been mineralized by hydrothermal activity. These geological processes create the conditions necessary for the formation of large, clear crystals of beryl, which can then be cut into gemstones.
Brazil is the most notable source of high-quality aquamarine gemstones. The country produces some of the most vibrantly colored and largest aquamarine crystals in the world. Other significant sources include Nigeria, Madagascar, Pakistan, and the United States. Despite the global distribution of aquamarine deposits, Brazil remains the premier source for gem-quality material due to the superior clarity and saturation of its blue hues.
Aquamarine is often found in transparent to translucent form, with a glassy luster that enhances its visual appeal. Unlike emerald, another member of the beryl family, aquamarine is typically free from inclusions and fractures, making it more durable and affordable. This abundance of high-clarity stones has contributed to aquamarine's popularity as a gemstone for jewelry.
Gemological Properties
Aquamarine is characterized by a range of gemological properties that make it a desirable and durable gemstone. Here are some of the key properties:
Color
Aquamarine is known for its pale blue to blue-green coloration. The gemstone's color is caused by the presence of iron in its crystal structure. The intensity of the blue hue can vary, with some stones exhibiting a very light, almost imperceptible color, while others have a rich, vibrant blue. The most valuable and sought-after aquamarines are those with a deep blue color and high clarity.
Clarity
Aquamarine is generally considered to be a high-clarity gemstone. Most aquamarine specimens are free from inclusions and fractures, making them more durable and less prone to damage. This clarity is one of the factors that contributes to aquamarine's popularity in jewelry.
Hardness
Aquamarine has a hardness of 7.5 to 8 on the Mohs scale. This level of hardness makes it suitable for a wide range of jewelry applications, including rings, earrings, and pendants. Its durability ensures that it can withstand daily wear without easily scratching or chipping.
Luster and Transparency
Aquamarine has a glassy luster and is typically transparent to translucent. The transparency of the gemstone allows light to pass through it, creating a brilliant and sparkling appearance when cut and polished.
Cut and Shape
Aquamarine is commonly cut into faceted shapes to enhance its brilliance and showcase its color. The most popular cuts include round, oval, and emerald cuts. Translucent aquamarine is sometimes cut into beads or cabochons, particularly in jewelry pieces that feature pastel blue aquamarine and morganite.
Specific Gravity
Aquamarine has a specific gravity of around 2.66 to 2.80. This is relatively moderate for a gemstone and contributes to its overall weight and density.
Refractive Index
Aquamarine has a refractive index of 1.56 to 1.60. This range is consistent with the refractive index of other beryl varieties and contributes to the gemstone's optical properties.
Symbolism and Metaphysical Beliefs
Aquamarine has been associated with a range of symbolic and metaphysical beliefs throughout history. These beliefs have varied across cultures and time periods but often share common themes of protection, calm, and communication.
Protection and Calm
One of the most enduring beliefs about aquamarine is its ability to provide protection and calm. Ancient mariners believed that the gemstone could calm the waves and ensure safe passage across the seas. This belief was rooted in the idea that aquamarine had the power to protect travelers from danger and bring peace in times of stress. This symbolism continues to resonate with many people today, particularly those who travel frequently or seek a sense of calm in their daily lives.
Communication and Expression
Aquamarine is also associated with communication and expression. It is believed to enhance the ability to speak truthfully and to express oneself clearly. In some traditions, aquamarine is considered a stone of the throat chakra, which governs communication and self-expression. This belief has led to the use of aquamarine in practices that emphasize clear and honest communication, such as public speaking and interpersonal relationships.
Emotional Balance and Harmony
Aquamarine is thought to promote emotional balance and harmony. It is believed to relieve anxiety and bring a sense of inner peace. This property has made aquamarine a popular gemstone for those seeking emotional stability and resilience. In some traditions, aquamarine is also used to support those in positions of leadership, as it is believed to enhance wisdom and judgment.
Modern Metaphysical Beliefs

It is also believed to support those who are facing difficult situations, as it is considered a stone of courage and confidence. Additionally, aquamarine is sometimes used in meditation and spiritual practices to promote a sense of calm and connection.
Care and Cleaning
To preserve the beauty and integrity of aquamarine jewelry, it is important to follow proper care and cleaning instructions. Here are some guidelines for maintaining aquamarine gemstones:
Avoid Harsh Chemicals
Aquamarine should be cleaned using mild, non-abrasive solutions. Harsh chemicals, such as bleach or ammonia, can damage the gemstone’s surface and affect its color and clarity. It is best to use a gentle soap solution and a soft cloth to clean aquamarine jewelry.
Store Properly
Aquamarine should be stored in a cool, dry place away from direct sunlight. Exposure to high temperatures and prolonged sunlight can cause the gemstone to fade or lose its luster. It is also advisable to store aquamarine separately from other gemstones to prevent scratches or abrasions.
Avoid Extreme Temperatures
Aquamarine should be kept away from extreme temperatures, as this can cause the gemstone to crack or become brittle. Avoid exposing aquamarine to sudden temperature changes, such as moving from a hot environment to a cold one, as this can lead to thermal shock.
Handle with Care
Aquamarine, while relatively durable, should be handled with care to avoid chipping or breaking. Avoid dropping the gemstone or subjecting it to heavy impact. When wearing aquamarine jewelry, it is advisable to remove it before engaging in activities that may cause physical stress or damage.
Professional Cleaning
For deep cleaning or to restore the gemstone’s brilliance, it is advisable to seek the services of a professional jeweler. A jeweler can use specialized tools and techniques to clean and polish aquamarine without causing damage.
