The aquamarine, with its tranquil blue hue reminiscent of the sea, stands as the traditional birthstone for the month of March. A member of the beryl mineral family, which also includes emeralds and morganite, this gemstone has captivated humanity for centuries. Its name, derived from the Latin words aqua (water) and marina (sea), perfectly encapsulates its most defining characteristic: a color that ranges from a faint, airy blue to a deep, saturated sky blue. Beyond its visual appeal, aquamarine is steeped in a rich history of lore and symbolism, believed by ancient civilizations to offer protection to sailors and ensure a safe voyage. It is also the designated gemstone for the 19th wedding anniversary, marking it as a token of enduring love and commitment.
As a gemstone, aquamarine is prized not only for its color but also for its remarkable durability and clarity. With a Mohs hardness of 7.5 to 8, it is sufficiently robust for everyday wear, making it an excellent choice for jewelry such as rings and engagement rings. Its relative lack of inclusions allows it to be cut into a variety of shapes, from classic emerald cuts to brilliant ovals and pears, each designed to maximize its inherent brilliance. This article will explore the multifaceted nature of aquamarine, delving into its geological origins, the spectrum of its color, its historical significance and metaphysical beliefs, its most prominent mining locations, and the practical aspects of its care and maintenance.
History and Lore
The history of aquamarine is as deep and enduring as the oceanic hues it embodies. For centuries, this gemstone has been a subject of fascination, weaving its way through ancient folklore, maritime traditions, and modern royal history. Its legacy is built upon a foundation of protective qualities and symbolic meanings that have evolved over time.
One of the most enduring legends associated with aquamarine is its connection to the sea. Ancient sailors, particularly the Romans, believed the stone was sacred to Neptune, the god of the sea, and that it possessed the power to ensure a safe and prosperous journey across treacherous waters. They would often carry aquamarine amulets engraved with the image of Neptune or throw the gemstones into the sea as offerings to appease the sea god, thereby calming the waves and protecting their ships from storms. This belief in its protective power extended beyond physical safety; it was also thought to be a powerful antidote to poison and a purifier of water, lending credence to its association with healing and renewal.
Beyond its maritime significance, aquamarine has long been a symbol of love, happiness, and youth. The gemstone was often gifted to newlyweds as a token of love and fidelity, and it was believed to rekindle the passion between couples. Its serene blue color was thought to embody the purity of spirit and the exhilaration of life, promoting emotional balance and quelling anger. In ancient times, it was believed that wearing aquamarine could bring about happiness, health, and eternal life.
This rich historical symbolism finds a modern echo in the choices of royalty. Princess Diana was famously fond of aquamarine jewelry, often wearing large, statement pieces that highlighted the stone’s vibrant color. Her legacy continues through her daughter-in-law, Meghan, the Duchess of Sussex, who wears an engagement ring that features a prominent central diamond flanked by two smaller diamonds from Princess Diana’s private collection. A notable piece in this collection is an aquamarine ring, which Meghan has worn on multiple occasions, linking generations through this striking and meaningful stone. This royal endorsement has further cemented aquamarine’s status as a gemstone of elegance, sophistication, and timeless appeal.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its characteristic blue-to-blue-green coloration resulting from trace amounts of iron within its chemical structure (Be₃Al₂Si₆O₁₈). It forms within hexagonal crystals that can grow to impressive sizes, often found in pegmatites and metamorphic rocks. The formation process requires specific geological conditions, including the presence of beryllium and aluminum, along with the iron that imparts its signature hue. These large, well-formed crystals are what allow for the creation of significant, high-quality gemstones suitable for elaborate jewelry pieces.
The primary and most prolific source of aquamarine is Brazil, particularly the states of Minas Gerais and Bahia. It is from these regions that some of the largest and most spectacular aquamarine crystals in history have been unearthed. One of the most famous discoveries occurred in the 1910s in Brazil, where a single crystal weighing approximately 240 pounds (over 100 kilograms) and measuring 19 inches in length was found. This monumental find showcased the potential for aquamarine to exist in truly massive forms, far beyond what is typically seen in commercial jewelry.
While Brazil dominates the market in terms of volume and historical finds, high-quality aquamarine is also sourced from numerous other locations across the globe, contributing to a diverse and global supply chain. Other common and important mining countries for these beautiful gemstones include:
- Africa: Kenya, Madagascar, Malawi, Angola, Nigeria, Mozambique, Tanzania, and Zambia.
- Asia: Pakistan.
- Europe: Russia.
- North America: Parts of Colorado in the United States.
The geographical diversity of these sources means that aquamarine can exhibit slight variations in tone and saturation depending on its origin. However, the most sought-after color, a medium to medium-deep blue, is consistently associated with the finest Brazilian stones. The availability of aquamarine from so many different parts of the world ensures that it remains accessible to a wide range of consumers, from those seeking a simple, elegant piece to collectors looking for a rare, large-scale specimen.
Gemological Properties
Understanding the gemological properties of aquamarine is essential to appreciating its value and suitability for jewelry. These scientific characteristics define its beauty, durability, and overall quality. As a member of the beryl family, aquamarine shares many properties with its relatives, but its unique iron content sets it apart.
Color: The most celebrated attribute of aquamarine is its color. It can range from a very light, almost colorless pale blue to a rich, deep sky blue. The lighter, less saturated shades are more commonly found in the market, while the deeper, more intense blues command higher prices. The color is generally considered to be more desirable when it is not too dark, allowing light to pass through the stone and enhance its brilliance.
Hardness and Durability: Aquamarine registers between 7.5 and 8 on the Mohs scale of mineral hardness. This places it among the more durable gemstones, making it highly resistant to scratching and suitable for all types of jewelry, including rings, earrings, and bracelets that are subject to daily wear. Its toughness is also good, meaning it is less likely to chip or break upon impact compared to more fragile gems.
Clarity: A key feature of aquamarine is its exceptional clarity. High-quality stones are typically "eye-clean," meaning they lack visible inclusions or imperfections to the naked eye. This high degree of transparency allows for superior light performance, giving the gemstone a brilliant and lively appearance. The ability to be cut into various shapes without compromising its clarity makes it a favorite among jewelers and designers.
Cut and Carat Weight: Due to its excellent clarity and lack of inclusions, aquamarine is an ideal stone for a wide variety of cuts. It is frequently found in emerald cuts, which showcase the stone's clarity and color, as well as oval, pear, marquise, and heart shapes. Because large crystals are more common with aquamarine than with many other colored gemstones, aquamarines of over 10 carats are not unusual, and exceptionally large stones can be acquired at a price per carat that is often more reasonable than for other gems of comparable size.

Symbolism and Metaphysical Beliefs
The symbolism and metaphysical beliefs surrounding aquamarine are as vast and deep as the ocean it is named after. For millennia, this gemstone has been attributed with a wide array of powers, from protecting travelers to healing the spirit. These beliefs, rooted in ancient lore and passed down through generations, continue to resonate with many people today, adding a layer of spiritual significance to the stone's physical beauty.
The primary and most ancient symbolism of aquamarine is its connection to the sea and its power to protect those who travel upon it. This belief was so strong that it was often called the "sailor's gem." It was thought to be a talisman of good luck and protection against the dangers of the ocean, ensuring a safe passage. This protective quality was not limited to sea voyages; it was also believed to shield against enemies in battle and to protect the wearer from accusations and legal troubles.
In addition to its protective powers, aquamarine is widely regarded as a stone of emotional healing and balance. Its serene blue color is thought to have a calming effect on the mind and emotions. It is said to help quell anger, soothe fears, and reduce stress and anxiety, allowing the wearer to achieve a state of inner peace and tranquility. By promoting emotional clarity, aquamarine is believed to help individuals release old, stagnant patterns and embrace new beginnings.
Furthermore, aquamarine is associated with love and relationships. It was traditionally believed to rekindle the flame of love between couples and to ensure fidelity and happiness in marriage. This makes it a popular choice for anniversary gifts, particularly the 19th, as it symbolizes the enduring and pure nature of a long-term partnership. It is also thought to attract love and affection into one's life, making it a meaningful gift for those seeking to build new relationships.
Finally, aquamarine is connected to themes of renewal and rebirth. Its connection to water—a universal symbol of cleansing and purification—makes it a powerful tool for spiritual cleansing. It is believed to purify the aura and align the chakras, promoting a free flow of energy throughout the body. This purifying effect extends to the physical realm as well, with ancient lore suggesting it could purify water and act as an antidote to poison. In this way, aquamarine is seen as a stone that can cleanse and rejuvenate the body, mind, and spirit, helping the individual to start anew with a clear heart and a calm mind.
Care and Cleaning
Due to its impressive hardness and good toughness, aquamarine is a relatively low-maintenance gemstone that is well-suited for everyday jewelry. However, proper care is still necessary to preserve its brilliance and ensure its longevity. Understanding its physical properties is key to knowing how to best protect and clean it.
With a Mohs hardness of 7.5 to 8, aquamarine is resistant to scratching from most everyday materials. It can be safely worn in rings, pendants, and earrings without a high risk of damage from casual contact. However, it is still softer than sapphire and diamond, so it should be stored separately from these harder stones to prevent it from being scratched. It is also advisable to remove aquamarine jewelry before engaging in activities that could subject it to hard blows, as a strong impact could potentially cause chipping, especially at the corners of a faceted stone.
Cleaning aquamarine is a straightforward process. The best method is to use warm, soapy water and a soft brush, such as a toothbrush. Gently scrub the stone and its setting to remove any dirt, oils, or lotions that may have accumulated. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. It is important to avoid harsh chemicals, such as bleach or ammonia, which could damage the stone or the metal setting.
Ultrasonic cleaners are generally safe for aquamarine, provided the stone is not included or fractured. However, it is best to avoid steam cleaners, as the high heat and pressure can potentially cause damage to the gemstone, especially if it has been fracture-filled or has existing inclusions. For most commercially available aquamarine jewelry, a simple cleaning with warm, soapy water is the safest and most effective method to maintain its luminous allure.
