Aquamarine, the captivating birthstone for those born on March 13, is a gemstone whose name is derived from the Latin words aqua marina, meaning "water of the sea." This gemstone is celebrated for its serene blue-green hues, evoking the tranquil depths of the ocean and symbolizing peace, clarity, and protection. Beyond its aesthetic appeal, aquamarine is revered in both historical and contemporary contexts for its spiritual associations, gemological properties, and cultural significance. As a member of the beryl family, it shares a mineralogical lineage with emerald, yet possesses a distinct character that has made it a favorite among jewelers, collectors, and spiritual seekers for millennia. This article delves into the multifaceted nature of the March 13 birthstone, exploring its geological formation, historical lore, gemological properties, symbolic meanings, and practical care requirements to preserve its enduring beauty.
History and Lore
Aquamarine has a long and storied history, with roots stretching back to ancient civilizations. Its connection with the sea is not merely visual; it is deeply rooted in historical lore and myth. Ancient mariners claimed the gem would calm waves and keep sailors safe at sea, carrying aquamarine as a talisman to ensure safe voyages and to protect against tempestuous waters. This belief in its protective power extended beyond the ocean, with some ancient cultures attributing to beryl (the mineral family to which aquamarine belongs) the ability to give the wearer protection against foes in battle and litigation. It was also thought to make the wearer unconquerable and amiable, and to quicken the intellect.
The stone’s significance in historical and religious contexts is further underscored by its potential inclusion in foundational gemstone lists. Most traditional birthstone lists are based on biblical mentionings of Aaron's breastplate gemstones or the gems from the foundation of New Jerusalem, though the specific identification of stones in these ancient texts is a subject of ongoing scholarly debate. Aquamarine’s enduring presence in these historical narratives speaks to its longstanding cultural value.
In more recent history, aquamarine has been a gem of royalty and statecraft. A notable example is the dark blue rectangular step-cut aquamarine given to First Lady Eleanor Roosevelt by the government of Brazil in 1936, which weighed an impressive 1,298 carats. This gift not only highlights the gem’s aesthetic appeal but also its status as a stone of diplomatic and personal significance. Beyond its use in state regalia, aquamarine has been cherished for its association with happiness in marriage and is traditionally given as a present on the 19th wedding anniversary, symbolizing enduring love and commitment.
Geological Formation and Sources
Aquamarine is a member of the beryl family, a group of minerals that includes emerald. The beryl family is composed of beryllium aluminum silicate, and the different colors of beryl gemstones are caused by trace elements within the crystal structure. In the case of aquamarine, the blue color is due to the presence of iron (Fe²⁺) within the crystal lattice. The intensity of the blue color is often related to the concentration of iron, with higher levels typically producing deeper, more saturated hues.
Aquamarine forms in igneous and metamorphic rock environments, where it crystallizes from magma or is transformed under high heat and pressure. It is typically found in granitic pegmatites and metamorphic rock formations, often in association with other minerals such as mica, quartz, and feldspar. These geological settings are crucial for the formation of large, high-quality crystals, which are prized for gemstone use.
While the provided sources do not specify exact mining locations, the geological characteristics described align with known global sources for aquamarine. Major deposits are found in Brazil, which is a leading producer of high-quality aquamarine, as well as in countries like Madagascar, Nigeria, and Pakistan. The association with Brazil is particularly notable given the historical gift of a large Brazilian aquamarine to Eleanor Roosevelt, suggesting the country's long-standing reputation for producing exceptional stones.
Gemological Properties
Aquamarine is prized for its physical and optical characteristics, which make it both durable and visually striking. Its most defining feature is its color, which ranges from deep green-blue to light, slightly greenish blue hues. Faceted aquamarines are often free from inclusions and as clear as water, symbolizing purity of spirit and soul. This clarity is a hallmark of high-quality aquamarine, though natural stones can contain inclusions that are sometimes accepted as proof of their natural origin.
As a member of the beryl family, aquamarine possesses a hardness of 7.5 to 8 on the Mohs scale, making it a relatively durable gemstone suitable for various types of jewelry, including rings, pendants, and bracelets. Its chemical formula is Be₃Al₂Si₆O₁₈, and it has a trigonal crystal system. The refractive index of aquamarine typically ranges from 1.577 to 1.583, with a birefringence of 0.005 to 0.009. These gemological properties contribute to its brilliance and light performance when properly cut.

Symbolism and Metaphysical Beliefs
Aquamarine’s symbolism is intrinsically linked to its oceanic color and historical lore. It is widely associated with calmness, courage, and emotional stability. For centuries, it has been believed to have the power to calm storms, protect sailors, and provide clarity. Today, it is still associated with calmness and courage, making it a meaningful gemstone for those born in March and for jewelry lovers who appreciate its calming energies.
For individuals born on March 13, aquamarine is particularly significant as it aligns with the traits of the Pisces zodiac sign. Pisces, which spans from February 19 to March 20, is known for its intuitive and empathetic nature. Aquamarine is thought to amplify these qualities by fostering inner peace and emotional stability, making it an ideal birthstone for those born during this period. The stone is also believed to promote spiritual protection and enhance communication, aligning with the compassionate and forgiving personality often associated with Pisces.
Beyond its connection to Pisces, aquamarine is also listed as an alternative gemstone for March-born individuals under various traditional lists. For example, some sources identify it as a high priest birthstone for March from an alternative list, further cementing its multifaceted spiritual significance. Its calming properties are not only valued in personal spiritual practices but also in modern contexts as a stone that can help reduce stress and anxiety, promoting a sense of tranquility and mental clarity.
Care and Cleaning
Due to its good hardness and lack of cleavage, aquamarine is relatively easy to care for, but it still requires proper handling to maintain its brilliance and longevity. To clean aquamarine jewelry, use warm, soapy water and a soft brush. For stubborn dirt, gently use a soft brush to remove debris. It is important to avoid harsh chemicals, ultrasonic cleaners, and sudden temperature changes, as these can potentially damage the stone or its setting.
When not in use, aquamarine jewelry should be stored in a soft pouch or a jewelry box with compartments to prevent it from coming into contact with harder stones that could cause scratches. Although aquamarine is quite durable, storing it separately from diamonds, sapphires, or rubies is a prudent practice. It is also advisable to keep it away from direct sunlight over prolonged periods, as some sources suggest that intense light exposure could potentially affect certain gemstones, though this is less of a concern for aquamarine compared to some other colored stones.
Regular maintenance, including professional cleaning and inspection of settings, will help ensure that aquamarine jewelry remains secure and sparkling. Its durability makes it an excellent choice for everyday wear, but as with all fine jewelry, it should be removed during strenuous activities to prevent impact or abrasion.
Conclusion
Aquamarine stands as a gemstone of profound beauty and significance, perfectly embodying the serene qualities of its namesake. As the primary birthstone for March 13, it offers a unique combination of historical depth, geological wonder, and symbolic meaning. From its ancient role as a talisman for sailors to its modern status as a cherished gem in fine jewelry, aquamarine continues to captivate and inspire. Its clear, blue-green hues, coupled with its remarkable durability and rich lore, make it a timeless choice for gemstone enthusiasts, jewelry buyers, and students of gemology alike.
