History and Lore
Aquamarine has long been admired for its beauty and symbolic associations. The gemstone’s name, derived from the Latin aqua marina, meaning "water of the sea," reflects its characteristic blue color and its historical connection to maritime themes. Ancient civilizations, including the Greeks and Romans, believed that aquamarine was formed from the tears of mermaids or from the foam of the ocean. Sailors wore aquamarine as a protective talisman, believing it could calm turbulent seas and ensure safe passage.
The gemstone’s association with royalty and nobility further enhanced its prestige. One of the most notable historical figures linked to aquamarine is Princess Diana, who was known to have a particular fondness for the gemstone. Her collection included aquamarine jewelry, and this legacy was continued when Meghan Markle received an aquamarine from Diana’s private collection as part of her engagement ring. This royal connection has contributed to aquamarine’s enduring popularity and has reinforced its status as a gemstone of elegance and significance.
In modern times, aquamarine has become a popular choice for engagement rings and wedding bands. Its durability and aesthetic appeal make it a practical alternative to more traditional gemstones like diamonds. Aquamarine is also the birthstone of March, and its use in jewelry is often tied to the month’s symbolism of new beginnings and renewal. As a traditional gift for the 19th wedding anniversary, it continues to be a meaningful and sentimental choice for couples seeking a gemstone that represents enduring love and harmony.
Geological Formation and Sources
Aquamarine is a member of the beryl family, which also includes emerald. It is a beryllium aluminum silicate mineral with the chemical formula Be₃Al₂(SiO₃)₆. The gemstone’s blue color is caused by the presence of iron (Fe²⁺) within the crystal structure. When beryl forms in granite pegmatite deposits, trace amounts of iron can enter the crystal lattice during the slow crystallization process, resulting in the characteristic blue hue of aquamarine. The intensity of the color can vary depending on the concentration of iron and the conditions under which the gemstone formed.
Aquamarine is found in various parts of the world, with the most notable sources being Brazil, Argentina, and Morocco. Brazil, in particular, is known for producing high-quality aquamarine with deep, rich colors. The gemstone is often mined in alluvial deposits, where it is found in riverbeds and sediment after being eroded from its original rock formations. The clarity and brilliance of aquamarine are enhanced by these natural processes, as the gemstone is freed from surrounding rock and transported by water.
In addition to its natural occurrence, aquamarine is sometimes heat-treated to improve its color and clarity. This treatment is common and can deepen the gemstone’s blue tones or remove any yellowish tinge. While untreated aquamarine is more valuable, heat-treated stones are still considered high-quality and are widely used in jewelry. However, it is important to note that heat-treated aquamarine can fade over time, especially when exposed to prolonged sunlight or high temperatures. This makes certification an essential factor when purchasing aquamarine jewelry, as it ensures the authenticity and quality of the gemstone.
Gemological Properties
Aquamarine is a highly durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This level of hardness makes it suitable for use in rings and bands, as it can withstand daily wear without significant damage. Its refractive index ranges from 1.56 to 1.60, which means it has a moderate to high level of light refraction. This property contributes to its brilliance and helps to enhance its color.
The gemstone is typically found in a range of blue shades, from light blue to aqua blue. The most valuable and desirable aquamarine is known for its deep, saturated blue color, which is often referred to as "maxixe" in the trade. The clarity of aquamarine is also a key factor in determining its value. High-quality aquamarine should be as free as possible from inclusions, as these can affect the gemstone’s transparency and brilliance. However, some inclusions are natural and can even be desirable, as they indicate the gemstone’s authenticity and origin.
The cut of an aquamarine plays a crucial role in maximizing its beauty. The emerald cut is particularly well-suited for aquamarine, as it highlights the gemstone’s clarity and soft color. Other popular cuts include oval, pear, and heart shapes, which can enhance the gemstone’s brilliance and make it more versatile in jewelry design. The choice of metal setting also affects the overall appearance of aquamarine. White gold, platinum, and silver are often preferred, as they complement the gemstone’s cool tones and create a harmonious and elegant look.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a wide range of symbolic and metaphysical properties. In ancient times, it was believed to have protective powers and was often used as a talisman for travelers and sailors. The gemstone was thought to calm the seas and ensure safe passage, making it a popular choice for maritime trade and exploration. This belief has persisted in various forms throughout history and continues to influence the gemstone’s use in modern jewelry.
In addition to its protective qualities, aquamarine is also associated with emotional and mental clarity. It is believed to promote a sense of calm and tranquility, making it a popular choice for those seeking balance and inner peace. This symbolism has contributed to its use in engagement rings and wedding bands, where it represents harmony and loyalty in relationships. The gemstone is also linked to communication and self-expression, and it is often used in meditation and spiritual practices to enhance clarity of thought and emotional stability.
The association of aquamarine with March as the birthstone further reinforces its symbolic significance. As the month of March is often seen as a time of renewal and new beginnings, aquamarine serves as a reminder of the potential for growth and transformation. Its use in jewelry is often tied to the idea of embracing change and moving forward with confidence. As a traditional gift for the 19th wedding anniversary, it also represents the enduring nature of love and the strength of long-term relationships.
Care and Cleaning
Due to its durability, aquamarine is a relatively easy gemstone to care for. However, there are a few important considerations to keep in mind to ensure its longevity and beauty. The gemstone’s hardness of 7.5 to 8 on the Mohs scale means it can withstand daily wear, but it is still susceptible to damage if not handled properly. Sharp blows or exposure to hard surfaces can cause chips or fractures, so it is important to store aquamarine jewelry separately from other gemstones and metals.
Cleaning aquamarine jewelry can be done using mild soap and warm water. A soft brush, such as a toothbrush, can be used to gently remove any dirt or debris. However, it is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone or its setting. Aquamarine can also be sensitive to heat, so it should not be exposed to high temperatures for extended periods. This is particularly important for heat-treated aquamarine, as prolonged exposure to sunlight or heat can cause the color to fade.
When caring for aquamarine rings and bands, it is also important to consider the metal setting. White gold, platinum, and silver are all suitable choices, but they may require different types of maintenance. For example, silver can tarnish over time, while white gold may need periodic replating. It is also a good idea to have the jewelry inspected by a professional jeweler on a regular basis to ensure that the setting remains secure and that the gemstone is properly protected.
Conclusion
Aquamarine is a gemstone of enduring beauty and significance, with a rich history and a wide range of symbolic meanings. From its ancient associations with the sea and protection to its modern role as the birthstone of March and a symbol of harmony and loyalty, aquamarine continues to captivate and inspire. Its durability, clarity, and stunning blue color make it a popular choice for rings and bands, particularly in engagement and wedding jewelry.
The gemstone’s geological properties, including its hardness, refractive index, and color variations, contribute to its versatility and appeal.
