Aquamarine: The Ocean Gem – History, Lore, and Properties

Aquamarine, the birthstone for March, is a gemstone deeply connected to the sea, both in its name and its captivating color. Evoking the tranquility of ocean waters, this highly valued gem has been prized for centuries for its aesthetic appeal, durability, and the beliefs surrounding its protective and harmonizing properties. This article will delve into the history, geological origins, gemological characteristics, symbolism, and care of aquamarine, drawing solely from available sources.

History and Lore

The name “aquamarine” originates from the Latin “aqua marina,” meaning “water of the sea,” a testament to its resemblance to the ocean’s hues. Ancient mariners held this gem in high regard, believing it possessed the power to calm waves and ensure safe passage. Beyond seafaring protection, aquamarine was thought to bring happiness in marriage and offer protection against foes in battle and legal disputes. It was believed to imbue the wearer with qualities of unconquerability, amiability, and intellectual sharpness.

Historically, beryl – the mineral family to which aquamarine belongs – was considered a protective stone. In ancient times, the gem was believed to turn the sun red if placed in water, a testament to its perceived power over natural forces. The gem’s association with courage and clarity extends back centuries, solidifying its place in folklore and tradition. A notable historical instance of aquamarine’s significance is the presentation of a 1,298-carat rectangular step-cut aquamarine to First Lady Eleanor Roosevelt by the Brazilian government in 1936. This impressive stone is now housed at the Franklin D. Roosevelt Presidential Library and Museum in Hyde Park, New York. Further demonstrating its grandeur, the Dom Pedro Aquamarine, believed to be the largest faceted aquamarine in the world at 10,363 carats, is a celebrated attraction at the Smithsonian Institution, skillfully crafted into a 14-inch obelisk using the fantasy cut technique. Aquamarine is also traditionally gifted on the 19th wedding anniversary.

Geological Formation and Sources

Aquamarine is a variety of the mineral beryl, composed of beryllium aluminum cyclosilicate. It is celebrated for its clarity and durability, stemming from its formation process and chemical composition. The gem is mined in various locations around the world, with Brazil’s Minas Gerais state being a particularly important source for the past two centuries. The landscape of Minas Gerais, characterized by rocky hills, rivers, and scrub brush, yields aquamarine in both primary (hard rock) and secondary (weathered) pegmatite deposits.

Beyond Brazil, significant aquamarine deposits are found in the challenging terrain of the Karakorum foothills of Pakistan. Mining in this region requires climbing steep paths to elevations between 9,800 and 13,000+ feet to work the sides of cliffs. The resulting aquamarine is often described as “water clear.” Additional sources include Kenya, Madagascar, Nigeria, Zambia, and Mozambique in Africa, as well as the United States – specifically the Mount Antero area of Colorado (which has designated it as the state gem) and Riverside and San Diego counties in California. Other countries where aquamarine has been found include China, Myanmar, Russia, and Ukraine.

Gemological Properties

Aquamarine boasts a hardness ranging from 7.5 to 8 on the Mohs scale, making it sufficiently durable for everyday wear. This hardness contributes to its suitability for various jewelry settings. The gem’s color spectrum ranges from deep green-blue to light, slightly greenish-blue hues, often exhibiting exceptional clarity and transparency. Faceted aquamarines are frequently free from inclusions, resembling clear water in their purity.

Aquamarine belongs to the beryl family, sharing its chemical composition with other well-known gems like emerald. Its clarity, durability, and subtle yet powerful beauty contribute to its enduring appeal. The gem is typically cut as a faceted stone to maximize its brilliance, though cabochon cuts are also utilized.

Symbolism and Metaphysical Beliefs

Throughout history, aquamarine has been imbued with symbolic meaning. It represents peace, happiness, and good fortune. Sailors and travelers have long believed in its ability to ward off negative energy and protect the wearer from danger, fostering a sense of calm and mental clarity.

While aquamarine is the primary March birthstone, bloodstone (heliotrope) shares this designation. Bloodstone, a variety of chalcedony, is a dark-green jasper with red inclusions of iron oxides. Historically, bloodstone was believed to have various metaphysical properties, including increasing strength, granting invisibility, and preserving health and youth. In modern times, it is often considered a lucky charm, particularly prized by athletes seeking to enhance their physical prowess. In some traditions, particularly in India, crushed bloodstone has been used as an aphrodisiac.

Care and Cleaning

Maintaining the beauty of aquamarine is relatively straightforward due to its durability. Routine cleaning can be performed with warm water, mild dish soap, and a soft toothbrush to remove dirt accumulation behind the stone. Ultrasonic cleaners and steam cleaning are generally safe, provided the gem does not contain fractures or liquid inclusions. For bloodstone, the same warm soapy water and soft brush method is recommended, but it should be kept away from harsh chemicals and extreme temperatures. Storing both aquamarine and bloodstone in soft fabric will help prevent scratches, as bloodstone has a lower hardness (6.5-7 on the Mohs scale).

Conclusion

Aquamarine, the “ocean gem,” stands as a testament to the enduring allure of natural beauty and the rich tapestry of human belief. From its ancient origins as a protector of sailors to its modern status as a cherished birthstone and anniversary gift, aquamarine continues to captivate with its serene color, durability, and symbolic significance. Its geological origins, spanning continents and challenging terrains, contribute to its rarity and value. Whether admired for its aesthetic qualities or its perceived metaphysical properties, aquamarine remains a gemstone of enduring appeal and timeless elegance.
