History and Lore
Aquamarine has a long and storied history that spans cultures and centuries. The name "aquamarine" comes from the Latin words aqua (water) and mare (sea), a reference to its color and the belief that it was formed from the sea itself. Ancient civilizations, particularly those with maritime traditions, held aquamarine in high regard.
In ancient Greece and Rome, aquamarine was thought to be a gift from the gods of the sea. Sailors wore it as an amulet to protect them from shipwrecks and to calm the waters. The gemstone was also believed to bring good fortune and to help one find courage in times of fear. These beliefs were so deeply rooted in maritime culture that aquamarine became a symbol of safety and guidance for those who braved the open ocean.
The use of aquamarine in jewelry dates back to the Renaissance, when it was incorporated into royal regalia and religious artifacts. By the 19th and 20th centuries, aquamarine had become a popular gemstone in fine jewelry, especially in Europe. The British royal family, in particular, has a long history with aquamarine. Notably, Princess Diana was a devoted fan of aquamarine jewelry. Her aquamarine collection was so renowned that it was passed down to Meghan Markle, who wore an aquamarine engagement ring from Diana’s private collection. This connection to royalty has only increased the gemstone’s prestige and appeal.
As a birthstone, aquamarine has been associated with March since at least the early 20th century. It is believed to promote calmness, clarity of thought, and emotional balance, making it a fitting symbol for those born in the month of transition between winter and spring. In addition, aquamarine is the traditional gemstone for the 19th wedding anniversary, marking nearly two decades of enduring love and partnership.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which also includes emerald (green beryl) and morganite (pink beryl). Its blue color is due to the presence of iron impurities within the beryl crystal structure. The gemstone is typically found in granite pegmatites and metamorphic rocks, often in association with other minerals such as quartz and topaz.
The formation of aquamarine involves the slow cooling of molten rock deep within the Earth’s crust. Over time, the iron in the beryl crystals reacts with trace amounts of water and other elements, producing the characteristic blue coloration. The intensity of the blue can vary depending on the concentration and oxidation state of the iron, with lighter blues being more common than deep sapphires.
Major sources of aquamarine include Brazil, Nigeria, Madagascar, and Pakistan. Brazil, in particular, is known for producing some of the highest-quality aquamarine in the world, especially from the Minas Gerais and Bahia regions. These deposits yield large, clear crystals that are ideal for faceting and jewelry. Other notable sources include the United States (especially California), Zambia, and Afghanistan.
The mining of aquamarine is typically done through open-pit or underground methods, depending on the location and depth of the deposits. Once extracted, the raw crystals are cut and polished to bring out their natural brilliance. Because of its hardness and durability, aquamarine is often used in rings, pendants, and earrings, where it can withstand daily wear without losing its luster.
Gemological Properties
Aquamarine is a gemstone of exceptional beauty and durability, making it a favorite among jewelers and collectors. Below are the key gemological properties of aquamarine, based on the information provided in the sources:
- Chemical Formula: Be₃Al₂(SiO₃)₆
- Color: Ranges from light blue to deep blue, with some specimens exhibiting a blue-green hue.
- Hardness (Mohs Scale): 7.5–8
- Refractive Index: 1.57–1.58
- Specific Gravity: 2.67–2.83
- Luster: Vitreous (glassy)
- Transparency: Transparent to translucent
- Crystal System: Hexagonal
- Cleavage: Perfect in one direction (basal)
- Common Cuts: Oval, round, emerald, pear, marquise, and hexagon
- Common Accents: Diamonds, moissanite, and other colored gemstones such as sapphire, topaz, and amethyst
Aquamarine is typically colorless in its purest form, but the presence of iron gives it its signature blue color. The gemstone is often treated with heat to enhance its color, a process that is both common and acceptable in the gem trade. Heat treatment removes any greenish tones and intensifies the blue, resulting in a more desirable and valuable gemstone.
The high hardness of aquamarine makes it suitable for a wide range of jewelry settings, including prong, bezel, and channel settings. Its vitreous luster and transparency allow for excellent light return, making it a radiant gemstone that can rival diamonds and sapphires in brilliance.
In modern jewelry, aquamarine is often paired with precious metals such as 14k gold, 18k gold, white gold, and platinum. These metals complement the gemstone’s cool blue tones and provide a sturdy setting for everyday wear. Some aquamarine rings also feature diamond or moissanite accents, which add sparkle and contrast to the gemstone.
Symbolism and Metaphysical Beliefs
Beyond its physical beauty and durability, aquamarine has been associated with a wide range of symbolic and metaphysical properties. In many cultures, it is believed to promote inner peace, calmness, and emotional stability. It is often used as a meditation stone to help quiet the mind and enhance spiritual awareness.
Aquamarine is also associated with communication and self-expression. It is said to help individuals speak their truth with clarity and confidence, making it a popular choice for those who wish to overcome fear or anxiety. In some traditions, aquamarine is believed to soothe the throat chakra, facilitating healing and empowerment.
Another popular belief is that aquamarine promotes loyalty and fidelity in relationships. This makes it an especially fitting gemstone for engagement rings and wedding bands. As the birthstone for March, it is often given as a gift to celebrate new beginnings, whether in love, career, or personal growth.
While these metaphysical beliefs are not scientifically proven, they have been passed down through generations and continue to influence the way people choose and wear aquamarine. Whether worn for its beauty, its meaning, or its protective qualities, aquamarine remains a deeply cherished gemstone.
Care and Cleaning
To ensure the longevity and beauty of aquamarine jewelry, proper care and cleaning are essential. Aquamarine is a durable gemstone with a hardness of 7.5–8, but it can still be damaged by harsh chemicals, extreme temperatures, and physical impacts.
Here are some tips for caring for aquamarine jewelry:
- Cleaning: Use a soft cloth and mild soap with warm water to clean the gemstone. Gently scrub with a soft brush to remove dirt and debris. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the gemstone or weaken its setting.
- Storage: Store aquamarine jewelry separately from other gemstones to prevent scratches. Wrap the jewelry in a soft cloth or store it in a padded jewelry box to protect it from dust and physical contact.
- Avoiding Chemicals: Remove aquamarine jewelry before using household cleaners, swimming in chlorinated pools, or applying lotions and perfumes. Chemicals can dull the gemstone’s luster and potentially damage the metal setting.
- Professional Maintenance: Have aquamarine jewelry professionally cleaned and inspected at least once a year to ensure that the setting is secure and the gemstone remains in good condition.
By following these simple care guidelines, aquamarine jewelry can be enjoyed for many years to come, retaining its brilliance and beauty.
