Aquamarine, a gemstone celebrated for its serene blue hues reminiscent of the ocean, holds a prominent place as the birthstone for March. Belonging to the beryl family – a lineage that also includes the emerald – aquamarine has captivated humanity for centuries with its beauty, durability, and the symbolism associated with the sea. This article delves into the history, geological origins, gemological properties, and cultural significance of aquamarine, offering a comprehensive overview for enthusiasts, buyers, and students of gemology.
History and Lore
The allure of aquamarine dates back centuries, with its name itself derived from the Latin words “aqua” and “marina,” meaning “water of the sea.” Throughout history, this gemstone has been linked to notions of purity, exhilaration, and relaxation, mirroring the qualities of the ocean it represents. Folklore often refers to aquamarine as the “treasure of the mermaids,” and sailors historically carried it as a talisman for good luck and protection during voyages. Beyond seafaring traditions, aquamarine was utilized in prayer and meditation, valued for its calming and clarifying properties.
The stone’s association with royalty further enhances its historical significance. Princess Diana was particularly fond of aquamarine jewelry, and a piece from her private collection was incorporated into Meghan Markle’s engagement ring, creating a tangible link between generations through this striking gemstone. Aquamarine is also traditionally gifted to celebrate the 19th wedding anniversary, symbolizing enduring love and happiness.
Geological Formation and Sources
Aquamarine forms in pegmatite rocks, often alongside other beryl varieties like morganite and heliodor. These rocks are formed during the final stages of a magma’s crystallization, creating an environment conducive to the growth of large, well-formed crystals. The presence of trace elements, particularly iron, is responsible for aquamarine’s characteristic blue coloration.
The majority of aquamarine available today originates from Brazil, where exceptionally large crystals have been discovered – the largest ever found weighed approximately 240 pounds and measured 19 inches in length. However, significant deposits are also found in several other locations worldwide, including Kenya, Madagascar, Malawi, Angola, Nigeria, Mozambique, Pakistan, Tanzania, Russia, Zambia, and even parts of Colorado in the United States. The variety in sourcing contributes to the range of color shades observed in aquamarine gemstones.
Gemological Properties
Aquamarine is prized not only for its color but also for its excellent physical and optical properties. It boasts a hardness of 7.5 to 8 on the Mohs scale, making it a durable gemstone suitable for everyday wear, even in engagement rings. This hardness means it is not easily scratched, ensuring its brilliance is maintained over time.
The gem’s chemical formula is Be₃Al₂Si₆O₁₈, indicating its composition of beryllium, aluminum, silicon, and oxygen. Aquamarines can range in color from a faint, light blue to a deeper, sky blue, with lighter colors being more commonly available. The clarity of aquamarine is also noteworthy, with many stones exhibiting few inclusions, contributing to their brilliance.
Aquamarine’s versatility allows it to be cut into a variety of shapes, including oval, pear, emerald, marquise, and heart-shaped cuts, enhancing its aesthetic appeal. The gem’s physical makeup and durability make it an excellent choice for various jewelry settings.
Here's a table summarizing key gemological properties:
| Property | Value |
|---|---|
| Hardness (Mohs) | 7.5 - 8 |
| Chemical Formula | Be₃Al₂Si₆O₁₈ |
| Crystal System | Hexagonal |
| Specific Gravity | 2.67 - 2.78 |
| Refractive Index | 1.565 - 1.590 |
| Color | Light to Deep Blue |
Symbolism and Metaphysical Beliefs
Beyond its aesthetic qualities, aquamarine is imbued with rich symbolism and metaphysical beliefs. Historically, it was believed to possess restorative properties, rejuvenating both the body and mind. Many jewelry wearers believe that aquamarine’s energy can lift spirits, promote clear thinking, and offer provision and good luck. It is also thought to foster love and affection and even provide aid in legal matters.
The association with the sea continues to influence its symbolism, representing tranquility, serenity, and emotional balance. Some believe that wearing aquamarine can help to calm anxieties and promote emotional healing. This connection to water also links the gemstone to intuition and psychic abilities.
Aquamarine Jewelry and Designs
Aquamarine’s beauty lends itself to a wide range of jewelry designs. Rings, particularly aquamarine diamond rings, are a popular choice, showcasing the gemstone’s brilliance. Earrings, from simple solitaire designs to more elaborate halo settings, offer a subtle yet elegant touch. Pendants, available in various shapes like solitaires, hearts, and radiances, provide a versatile accessory.
The design possibilities are extensive, with options for customization regarding metal type (sterling silver, yellow gold, white gold, rose gold, and platinum), gemstone quality grade, and carat weight. Skilled artisans meticulously craft each piece, ensuring blessings and conveying the gemstone’s inherent beauty. Whether seeking a vintage aquamarine brooch or a striking birthstone necklace, a variety of styles are available to suit individual preferences.
Care and Cleaning
Maintaining the beauty of aquamarine jewelry is relatively straightforward due to its durability. Regular cleaning with warm, soapy water and a soft brush is generally sufficient to remove dirt and grime. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the gemstone. Given its hardness, aquamarine is resistant to scratching from everyday wear, but it’s still advisable to store it separately from other jewelry to prevent potential abrasions.
Conclusion

As the birthstone for March, it represents purity, youth, fidelity, health, hope, and eternal life. From its geological origins in pegmatite rocks to its diverse applications in jewelry design, aquamarine continues to enchant and inspire. Its durability, clarity, and range of blue hues make it a cherished gemstone for generations to come, embodying the tranquility and allure of the sea.
