History and Lore
Aquamarine has a storied history that spans centuries and cultures. Its name, derived from the Latin words aqua (water) and marina (of the sea), reflects its association with the ocean. Ancient mariners believed that aquamarine could calm stormy seas and protect sailors from the perils of the deep. This belief in its protective power extended beyond seafaring, with the gemstone also being thought to safeguard travelers and warriors in battle. In ancient times, aquamarine was believed to possess the power to make the wearer "unconquerable and amiable" while also quickening the intellect. These properties made it a coveted gemstone among leaders and warriors alike.
In medieval Europe, aquamarine was considered a symbol of hope and courage. It was often worn as a talisman during times of conflict and uncertainty. The gemstone’s calming blue color was thought to soothe the mind and promote emotional stability. During the Renaissance, aquamarine was featured in royal jewelry and became a symbol of nobility and grace. Its popularity among royalty and the aristocracy further cemented its status as a gemstone of prestige and beauty.
In the modern era, aquamarine’s reputation as a birthstone for March was officially recognized in the 20th century. This designation was influenced by its historical associations with protection, clarity, and emotional balance. Today, aquamarine is also celebrated as a gift for the 19th wedding anniversary, symbolizing enduring love and harmony. The gemstone’s journey from ancient talisman to modern birthstone reflects its enduring appeal and the universal desire for beauty and meaning in jewelry.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which belongs to the beryllium aluminum silicate family. It owes its distinctive blue color to the presence of iron ions within its crystal structure. The color intensity of aquamarine can vary from a pale, almost colorless blue to a deep, rich blue with a hint of green. This variation is influenced by the concentration of iron and the specific conditions under which the gemstone forms.
Aquamarine is typically formed in pegmatite deposits, which are igneous rocks that develop from the slow cooling of magma. These deposits are rich in rare elements, including beryllium and iron, which are essential for the formation of aquamarine. The gemstone is also found in secondary deposits, where it is weathered out of its original rock and transported by water or erosion. These secondary deposits often produce aquamarine with a clearer and more vibrant color due to the absence of internal inclusions.
One of the most significant sources of aquamarine is the Brazilian state of Minas Gerais, which has been a primary supplier of the gemstone for over two centuries. The region's diverse geological landscape, including rocky hills, rivers, and savannahs, provides ideal conditions for aquamarine formation. The eastern portion of Minas Gerais, near the gem center of Teófilo Otoni, is particularly renowned for its high-quality aquamarine deposits. These deposits include both primary (hard rock) and secondary (weathered) sources, ensuring a steady supply of gemstones with varying characteristics.
In addition to Brazil, aquamarine is found in several other countries around the world. Kenya, Madagascar, China, and Nigeria are notable sources, each contributing to the global market with their unique geological formations. In the United States, aquamarine can be sourced from the Mount Antero area of Colorado and from Riverside and San Diego counties in California. These domestic sources highlight the gemstone’s global distribution and the diverse environments in which it can form.
One of the most famous aquamarine specimens is the Dom Pedro Aquamarine, housed at the Smithsonian Institution. Weighing an impressive 10,363 carats (approximately 4.6 pounds), this gemstone is believed to be the largest faceted aquamarine in the world. It was crafted by German lapidary Berndt Munsteiner using the fantasy cut technique, which allows for intricate and artistic designs. The Dom Pedro Aquamarine is a testament to the beauty and rarity of this gemstone, showcasing its potential to captivate and inspire.
Gemological Properties
Aquamarine is a gemstone that stands out for its clarity, color, and durability. Its scientific properties make it a popular choice for jewelry, particularly for rings and pendants that are worn regularly. The gemstone is known for its high hardness on the Mohs scale, which measures the scratch resistance of minerals. Aquamarine has a hardness of 7.5 to 8, placing it just below topaz and above quartz. This hardness makes it suitable for everyday wear, as it is resistant to scratches and abrasions.
The refractive index of aquamarine is another important gemological property. It ranges from 1.56 to 1.60, which means that the gemstone can refract light effectively, creating a brilliant and sparkling appearance. The refractive index also affects the gemstone’s dispersion, or the ability to separate light into its component colors. While aquamarine is not as dispersive as diamonds or zircons, its clarity and color can still produce a beautiful and mesmerizing effect.
Aquamarine is also known for its excellent transparency. High-quality specimens are often free from inclusions and as clear as water, which enhances their brilliance and visual appeal. The absence of inclusions also makes aquamarine a desirable gemstone for collectors and jewelry designers who value clarity and purity. However, some inclusions can add character to the gemstone and may be considered a natural part of its beauty.
The color of aquamarine is one of its most distinguishing features. Its blue color can range from a pale, almost colorless blue to a deep, rich blue with a hint of green. This variation is influenced by the concentration of iron and the specific conditions under which the gemstone forms. The most valuable and sought-after aquamarine specimens are those with a deep blue color, as they are rarer and more visually striking.
Aquamarine is also available in various cuts, including oval, round, emerald, and fantasy cuts. The choice of cut can significantly affect the gemstone’s appearance and value. For example, the step-cut aquamarine given to Eleanor Roosevelt in 1936 by the Brazilian government is a notable example of a high-quality cut that enhances the gemstone’s clarity and color. Fantasy cuts, such as the one used for the Dom Pedro Aquamarine, allow for greater artistic expression and can create unique and intricate designs.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a range of symbolic and metaphysical properties. Its calming blue color is believed to promote emotional balance, tranquility, and mental clarity. These properties have made it a popular gemstone for those seeking peace and serenity in their lives. The gemstone is also associated with communication and self-expression, making it a symbol of truth and honesty. According to ancient mariners, aquamarine could calm stormy seas and protect sailors from the perils of the deep, reinforcing its reputation as a protective and stabilizing gemstone.
In modern times, aquamarine is often used in meditation and healing practices. It is believed to help reduce stress and anxiety, promote emotional healing, and enhance spiritual growth. The gemstone is also associated with the throat chakra, which is linked to communication and self-expression. Wearing aquamarine or using it in meditation is believed to help open the throat chakra, allowing for clearer and more honest communication. This property makes it a popular gemstone for those who work in fields that require effective communication, such as public speaking, counseling, or teaching.
Aquamarine is also associated with the heart chakra, which is linked to love, compassion, and emotional healing. The gemstone is believed to help heal emotional wounds and promote a sense of inner peace. It is often used in relationships to enhance understanding, trust, and harmony. The gemstone’s association with the sea and the moon also adds to its mystical appeal, as it is believed to enhance intuition and emotional sensitivity.
In many cultures, aquamarine is considered a symbol of hope and youthfulness. It is often given as a gift to celebrate new beginnings, such as a new job, a new home, or a new relationship. The gemstone is also associated with the arrival of spring, making it a fitting symbol for renewal and growth. These symbolic meanings have contributed to aquamarine’s enduring popularity as a birthstone and a meaningful gift.
Care and Cleaning
Aquamarine is a durable gemstone that can be worn and enjoyed for many years with proper care and maintenance. Its high hardness on the Mohs scale (7.5 to 8) makes it resistant to scratches and abrasions, but it is still important to handle it with care to avoid damage. Aquamarine can be cleaned with warm, soapy water and a soft cloth or brush. It is important to avoid using harsh chemicals or abrasive cleaners, as these can damage the gemstone’s surface or setting.
When storing aquamarine jewelry, it is best to keep it in a soft pouch or a lined jewelry box to prevent scratches and tangling. It is also advisable to store aquamarine separately from other gemstones, as harder gemstones can scratch softer ones. If aquamarine is set in a silver or gold setting, it is important to clean the metal regularly to maintain its luster and prevent tarnish. Sterling silver can be cleaned with a jewelry cloth or a mild silver polish, while gold can be cleaned with a soft cloth and warm, soapy water.
Aquamarine should also be protected from extreme heat and direct sunlight, as these can cause the gemstone to fade or lose its color. It is best to store aquamarine jewelry in a cool, dry place away from direct sunlight and heat sources. When wearing aquamarine, it is important to avoid exposing it to harsh chemicals, such as household cleaners, chlorine, or bleach, as these can damage the gemstone or its setting. It is also advisable to remove aquamarine jewelry before engaging in activities that may cause physical contact or impact, such as sports or manual labor.
If aquamarine jewelry requires professional cleaning or repair, it is best to take it to a reputable jeweler or gemologist. A professional can clean the gemstone using specialized techniques and equipment, ensuring that it remains in excellent condition. They can also inspect the setting for any signs of wear or damage and make necessary repairs to ensure the jewelry remains secure and beautiful.
