Aquamarine, the captivating blue to blue-green gemstone, holds the esteemed position of March’s modern birthstone. Alongside bloodstone, it represents the duality of the month – serenity and resilience – and has been cherished for centuries for its beauty, symbolism, and purported protective qualities. This article will delve into the history, geological origins, gemological properties, and cultural significance of aquamarine, providing a comprehensive overview of this remarkable gem.
History and Lore
The name “aquamarine” itself is derived from the Latin words “aqua” (water) and “marina” (sea), aptly describing the gem’s evocative color reminiscent of seawater. Throughout history, aquamarine has been steeped in legend and lore. Ancient mariners believed the gem possessed the power to calm the waves and ensure a safe voyage, serving as a protective charm against the perils of the ocean. This association with the sea extended beyond safety; aquamarine was also thought to bring happiness in marriage and symbolize lasting love and friendship.
Beyond seafaring traditions, ancient beliefs attributed aquamarine with the ability to offer clarity and foresight, allowing glimpses into the future. Beryl, the mineral family to which aquamarine belongs, was believed to give the wearer protection in battle and legal disputes, fostering amiability and quickening the intellect. The gem’s historical significance is further highlighted by its use as a gift; aquamarine is traditionally given as a present on the 19th wedding anniversary, symbolizing enduring affection.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, a beryllium aluminum cyclosilicate. It forms in pegmatite deposits, which are coarse-grained igneous rocks formed during the final stages of magma crystallization. These deposits often contain a variety of rare minerals, including other beryl varieties like emerald and morganite. Aquamarine crystals develop in long, hexagonal prisms, and their blue color is attributed to trace amounts of iron within the beryl’s chemical structure.
For the past two centuries, the Brazilian state of Minas Gerais has been a particularly important source of aquamarine. The region’s diverse landscapes – rocky hills, rivers, and savannahs – conceal both primary (hard rock) and secondary (weathered) pegmatite deposits. The gem center of Teófilo Otoni, located within Minas Gerais, is a key hub for aquamarine mining and processing. A notable example of Brazilian aquamarine is the 1,298-carat dark blue rectangular step-cut stone presented to First Lady Eleanor Roosevelt in 1936.
Another celebrated specimen, the Dom Pedro Aquamarine, resides at the Smithsonian Institution. This magnificent obelisk, weighing approximately 10,363 carats (4.6 pounds) and standing roughly 14 inches tall, was skillfully fashioned by German lapidary Berndt Munsteiner using the fantasy cut technique, showcasing the gem’s potential for artistic expression.
Gemological Properties
Aquamarine exhibits several key gemological properties that contribute to its desirability and durability. It consistently displays light color saturation and tone, meaning darker shades of blue or green are not typically found. The gem’s color ranges from a deep, yet pastel, blue to a nearly clear shade of blue. While darker stones may command higher values, many consumers prefer the lighter, clearer stones for their delicate beauty.
Aquamarine possesses good hardness, registering a 7 on the Mohs scale of mineral hardness. This makes it suitable for a wide range of jewelry applications, including rings, pendants, and earrings, as it is resistant to scratching during everyday wear. Notably, unlike other members of the beryl family, aquamarine lacks cleavage – a tendency to break along specific planes – and is typically free from inclusions, further enhancing its durability and transparency.
The following table summarizes key gemological properties:
| Property | Description |
|---|---|
| Mineral | Beryl (Be3Al2Si6O18) |
| Color | Blue to Blue-Green |
| Hardness (Mohs) | 7 - 7.5 |
| Cleavage | None |
| Transparency | Excellent |
| Luster | Vitreous (glass-like) |
| Crystal System | Hexagonal |
Symbolism and Metaphysical Beliefs
Throughout history, aquamarine has been imbued with symbolic meaning. As its name suggests, the gem is strongly associated with the sea, representing tranquility, clarity, and open communication. The ancient belief that aquamarine could calm waves and protect sailors underscores its connection to safety and well-being.
Beyond its maritime associations, aquamarine is also linked to youth, health, hope, and love. Some cultures associate the gem with superior intellect and marital happiness. While these metaphysical beliefs are not scientifically substantiated, they contribute to the gem’s enduring appeal and perceived power.
Care and Cleaning
Maintaining the beauty of aquamarine jewelry is relatively straightforward. Aquamarine should be stored separately from harder gemstones, such as diamonds, to prevent scratching. Soft pouches or fabric-lined jewelry boxes provide optimal protection. Exposure to extreme temperatures and direct sunlight should be avoided, and the gem should be stored in a cool, dark place.
Cleaning aquamarine jewelry can be accomplished with warm soapy water, a soft brush, and a soft cloth. This gentle cleaning method effectively removes dirt and grime without damaging the gem’s surface. Regular cleaning will help preserve aquamarine’s brilliance and ensure its lasting beauty.
Conclusion
Aquamarine, March’s captivating birthstone, embodies the serenity and resilience of the sea. From its ancient origins as a protective charm for sailors to its modern-day status as a symbol of clarity and hope, aquamarine has captivated people for centuries. Its beautiful blue hues, combined with its excellent durability and relative affordability, make it a popular choice for jewelry. Whether admired for its aesthetic appeal or cherished for its symbolic meaning, aquamarine remains a treasured gem, deserving of mindful stewardship and continued appreciation.
