Aquamarine, the captivating birthstone for those born on March 24th, is a gemstone whose very name translates to "water of the sea" in Latin. This light blue to greenish-blue variety of beryl has been treasured for centuries, embodying the tranquil hues of the ocean and carrying a legacy of protection, clarity, and courage. As the primary birthstone for March, aquamarine is celebrated not only for its serene beauty but also for its remarkable durability and rich historical lore. This article explores the gemological properties, historical significance, geological origins, and symbolic meanings of aquamarine, drawing from authoritative sources to provide a comprehensive overview of this cherished gem.
History and Lore
The history of aquamarine is deeply intertwined with the sea and maritime culture. Its name, derived from the Latin aqua marina, directly references the ocean, and ancient civilizations attributed profound powers to this sea-blue gem. Sailors of antiquity, including those from Greece and Rome, carried aquamarine as a talisman for safe passage, believing it could calm waves and ward off the perils of the sea. This protective association extended beyond the maritime realm; in medieval Europe, aquamarine was linked to divine protection and was often incorporated into religious artifacts.
Beyond its protective qualities, aquamarine was believed to possess properties that could soothe the mind and enhance courage. The Greeks and Romans associated the stone with sea gods, believing it could reduce anxiety and promote bravery. Medieval lore held that beryl, the mineral family to which aquamarine belongs, granted the wearer protection against foes in both battle and litigation. It was also thought to make the wearer unconquerable and amiable while quickening the intellect. The stone’s calming and healing properties were also emphasized, with modern interpretations suggesting it helps soothe stress and enhance communication, making it an excellent gift for those who appreciate the natural world and its calming influence.
Aquamarine’s journey to becoming a modern birthstone is part of a broader tradition that evolved over centuries. While the concept of birthstones has ancient roots, the standardized list used today is a more recent development. For March, aquamarine stands as the primary birthstone, a status it shares with an alternative: bloodstone. This dual representation offers those born in March a choice between the serene blue of aquamarine and the earthy, dark-green cabochon of bloodstone, which is characterized by red spots of iron oxide. The selection of aquamarine as the primary stone for March solidifies its association with the month, a connection further emphasized by its role as the Zodiac birthstone for Pisces (February 20 - March 20). Furthermore, aquamarine is traditionally gifted to celebrate the 19th wedding anniversary, adding to its significance as a stone of enduring commitment and lasting value.
Geological Formation and Sources
Aquamarine is a variety of beryl, a mineral composed of beryllium aluminum silicate. It forms in pegmatite deposits—coarse-grained igneous rocks—where conditions allow for the growth of large, well-formed crystals. The characteristic blue color of aquamarine is primarily attributed to trace amounts of iron within its crystal lattice. The intensity of the blue hue can vary, with the most prized shades ranging from a deep, vibrant blue to a lighter, slightly greenish-blue. Notably, naturally occurring aquamarine is often found in pale to almost transparent colors, with darker blue shades being relatively rare in the natural state.
While the provided sources do not specify exact mining locations, the historical and modern significance of aquamarine points to its global presence. A notable example from the 20th century underscores its value and the prestige associated with high-quality specimens. In 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a dark blue, rectangular step-cut aquamarine weighing an impressive 1,298 carats. This gift highlights Brazil as a significant source of large, high-quality aquamarine crystals. The gemological properties of aquamarine, such as its hardness and clarity, make it suitable for jewelry, and its formation in pegmatites allows for the extraction of sizable crystals that can be cut into impressive faceted stones.
Gemological Properties
Aquamarine is prized for its combination of beauty and durability, making it a popular choice for jewelry. Its gemological characteristics are well-defined and contribute to its value and wearability.
- Chemical Composition: Aquamarine is a variety of beryl, with the chemical formula Be₃Al₂Si₆O₁₈. Its blue color is due to trace amounts of iron (Fe²⁺ and Fe³⁺).
- Hardness: On the Mohs scale of mineral hardness, beryl registers between 7.5 and 8. This makes aquamarine a relatively hard and durable gemstone, resistant to scratching and suitable for daily wear in rings, earrings, and pendants.
- Crystal System: Aquamarine crystallizes in the hexagonal system, often forming well-defined, prismatic crystals that can be quite large.
- Refractive Index: The refractive index of beryl ranges from approximately 1.567 to 1.590, contributing to its brilliance when properly cut.
- Clarity: Faceted aquamarines are frequently noted for being free from inclusions, appearing as clear as water. This high clarity is a key factor in its aesthetic appeal and is often associated with purity of spirit and soul.
- Color: The gemstone’s color spectrum ranges from deep green-blue to light, slightly greenish blue. The most valued colors are a vivid, medium-blue without a dominant green tint. As noted, naturally occurring aquamarine is generally very pale to almost transparent, with darker shades being less common.
- Cut and Carat Weight: Aquamarine is often cut in styles that maximize its color and clarity, such as emerald cuts, step cuts, and brilliant cuts. Due to its formation in large crystals, it can be found in substantial carat sizes, with faceted stones commonly available in sizes larger than many other colored gemstones.

Symbolism and Metaphysical Beliefs
The symbolism of aquamarine is richly layered, drawing from its historical maritime connections and its perceived calming properties. Across cultures and eras, the stone has been a symbol of protection, clarity, and emotional balance.
The primary symbolism stems from its association with the sea. As a talisman for sailors, it represented safety, safe passage, and protection from storms. This connection to water also imbued it with meanings of purity, clarity, and flow. The gem’s ability to appear "clear as water" led to its association with purity of spirit and soul, making it a stone of spiritual cleansing and emotional release.
In terms of emotional and mental well-being, aquamarine is consistently described as a calming stone. Its serene blue hue is believed to soothe anxiety, reduce stress, and promote a sense of peace. This aligns with ancient beliefs that it could calm waves and, by extension, calm turbulent emotions. It is also linked to enhanced communication, thought to help individuals express themselves clearly and with compassion, reflecting its connection to the throat chakra in some metaphysical traditions.
Beyond its calming effects, aquamarine carries connotations of courage and strength. The ancient belief that it could make the wearer unconquerable in battle speaks to its symbolic power. This duality—calmness paired with inner strength—makes it a versatile symbol for personal growth, representing the ability to navigate life’s challenges with grace and resilience. As a modern birthstone, it symbolizes the personality and journey of those born on March 24th, representing serenity, strength, and an enduring connection between nature and human experience.
Care and Cleaning
Given its good hardness and lack of cleavage (a tendency to break along flat planes), aquamarine is a durable gemstone that is relatively easy to care for. However, proper maintenance is essential to preserve its beauty and integrity over time.
Cleaning: Aquamarine can be safely cleaned using warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally considered safe for aquamarine, provided the stone is free of fractures or significant inclusions. However, it is always advisable to inspect the stone for any damage before using these methods. Harsh chemicals, such as bleach or hydrofluoric acid, should be avoided as they can damage the gemstone or its setting.
Storage: When not being worn, aquamarine jewelry should be stored separately from other jewelry to prevent scratching. A soft pouch or a compartmentalized jewelry box is ideal.
Wearing Considerations: While aquamarine is durable enough for everyday wear, it is wise to avoid high-impact activities or handling sharp objects while wearing aquamarine jewelry to minimize the risk of chipping or cracking. When setting aquamarine in jewelry, secure settings such as prongs or bezels are recommended. Tension settings, which rely on pressure to hold the stone, should be avoided as they can increase the likelihood of the stone breaking.
By following these care guidelines, aquamarine jewelry can remain a beautiful and valuable heirloom for generations, maintaining its serene blue color and brilliant clarity.
