We will also examine its metaphysical and symbolic meanings, and offer practical advice on how to care for this beautiful gemstone.
History and Lore
Aquamarine’s history is deeply intertwined with the sea. Ancient mariners believed that the gemstone protected them from the dangers of the ocean and helped to calm turbulent waters. This belief made aquamarine a symbol of safety and serenity for sailors. In ancient Greece and Rome, the stone was thought to be a gift from the gods, and it was often carried by those embarking on long sea voyages. It was also believed that aquamarine could bring happiness in marriage and was a protective talisman in times of conflict or litigation.
The gemstone's use in jewelry and adornment dates back centuries. In medieval times, aquamarine was considered a sacred stone, often used in religious and royal settings. It was also associated with purity of spirit and the soul, which contributed to its popularity among nobility and clergy alike. One notable example of aquamarine's historical significance is the 1,298-carat aquamarine gifted to Eleanor Roosevelt by the government of Brazil in 1936, which remains one of the most famous examples of the gem in history.
In the early 20th century, the National Association of Jewelers standardized the list of birthstones, and aquamarine was officially recognized as the primary birthstone for March. This decision was influenced by aquamarine’s commercial appeal, as it is a durable and transparent gemstone, making it more suitable for a wide range to of jewelry designs compared to its traditional counterpart, bloodstone.
Despite this shift, aquamarine’s historical and symbolic associations have remained largely unchanged. It continues to be a symbol of calmness, clarity, and courage, and is believed to bring emotional healing and peace to its wearer.
Geological Formation and Sources
Aquamarine is a member of the beryl family, which includes other well-known gemstones such as emerald and morganite. Beryl is a silicate mineral composed of beryllium, aluminum, and silicon. The blue color of aquamarine is due to the presence of iron, which gives it its characteristic sea-like hue. The clarity and color of aquamarine can vary depending on the concentration of iron and the presence of other trace elements.
Aquamarine is typically found in granitic pegmatites and metamorphic rocks, where it forms under high-temperature conditions. These environments allow for the slow growth of large, well-formed crystals, which are often free from visible inclusions. This clarity is one of the reasons aquamarine is so highly valued in the gemstone market.
The primary source of aquamarine is Brazil, where the largest and highest-quality deposits are found. Other notable sources include Pakistan, Madagascar, Nigeria, Mozambique, and the United States (particularly in Colorado). The largest aquamarine crystal ever discovered weighed 243 pounds and was found in Brazil in 1910. These deposits have contributed to the widespread availability and popularity of aquamarine in the global jewelry market.
Aquamarine is often cut into faceted gems, which enhances its brilliance and showcases its clarity and color. The most desirable aquamarine stones are those that are clear, transparent, and have a medium to deep blue color. Stones with greenish undertones or pale blue tones are also valued, though the most prized specimens are those with a pure, vibrant blue hue.
Gemological Properties
Aquamarine is a durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. This makes it suitable for a wide range of jewelry applications, including rings, earrings, and pendants. Its durability is due in part to its crystal structure, which is relatively resistant to scratches and other forms of wear.
In terms of chemical composition, aquamarine is a beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. It is typically free from visible inclusions, making it a highly desirable gemstone for collectors and jewelry enthusiasts. Its refractive index ranges from 1.56 to 1.60, and it has a specific gravity of approximately 2.72.
One of the most notable characteristics of aquamarine is its color. The gemstone exhibits a range of blue hues, from pale and delicate to deep and intense. The most prized aquamarines are those with a clear, bright blue color that is free from greenish or grayish tones. The presence of iron in the crystal structure is responsible for the blue coloration.
Aquamarine is also relatively stable under normal conditions, but it can be sensitive to exposure to extreme heat or chemicals. Prolonged exposure to direct sunlight can cause the color to fade slightly, so it is advisable to store aquamarine jewelry in a cool, dark place when not in use.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with emotional healing, clarity, and peace. In modern metaphysical practices, it is believed to promote calmness and reduce stress, making it a popular choice for those seeking emotional balance and mental clarity. It is also considered a stone of communication, helping the wearer to express themselves more effectively and with greater confidence.
Historically, aquamarine has been linked to the sea and was believed to protect sailors from the dangers of the ocean. It was also associated with purity of spirit and the soul, and was thought to bring courage and strength to the wearer. These beliefs have persisted into modern times, with aquamarine being used in crystal healing and spiritual practices.
In addition to its calming properties, aquamarine is also believed to offer protection. It is thought to shield the wearer from negative energies and promote a sense of security and well-being. This makes it a popular choice for those who are seeking emotional stability or who are undergoing a period of change or transition.
Aquamarine is also associated with love and relationships. It is believed to enhance communication between partners and promote harmony and understanding in relationships. This is one of the reasons it is often used in engagement rings and other romantic jewelry pieces.
Care and Cleaning
Due to its durability, aquamarine can be cleaned using a variety of methods. However, it is important to avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or its setting. A gentle cleaning solution of mild soap and warm water is recommended for most aquamarine jewelry. This can be applied using a soft cloth or a soft-bristled brush, and the jewelry should be rinsed thoroughly in clean water afterward.
For deeper cleaning, ultrasonic cleaners can be used, but they should be used with caution, as they can sometimes cause damage to certain gemstone settings or inclusions. Steam cleaners are not recommended for aquamarine, as they can cause the stone to become overheated.
It is also important to store aquamarine jewelry separately from other gemstones, as it can be scratched by harder materials. A soft pouch or a lined jewelry box is ideal for storage. When not in use, it is best to keep aquamarine in a cool, dry place away from direct sunlight, as exposure to heat and light can cause the color to fade over time.
