The arrival of March brings with it the promise of spring, a transitional period marked by renewal and clarity. For those born in this month, the designated birthstone is aquamarine, a gem celebrated for its captivating range of blue hues, from the palest sky blue to the deep, saturated blues of the ocean. Its name, derived from the Latin aqua marina meaning "sea water," perfectly encapsulates its serene and watery appearance. As a member of the beryl family, aquamarine shares its lineage with other notable gems like emerald and morganite, yet it possesses a unique character that has made it a favorite for centuries.
Aquamarine's significance extends far beyond its role as a birthstone. It has been treasured by sailors for protection, valued by mystics for its calming energies, and sought after by jewelers for its remarkable clarity and durability. In the modern market, it is frequently set in gold, a metal whose warm luster provides a stunning contrast to the gem's cool tones. This article will explore the multifaceted nature of aquamarine, from its historical lore and geological origins to its gemological properties and its place in contemporary jewelry design, particularly in combination with gold.
History and Lore
Aquamarine’s history is steeped in legend and practicality, particularly concerning its relationship with the sea. Ancient mariners believed the gem was a treasure of mermaids and would carry it as a talisman to ensure safe passage and protect against drowning. Its powers were thought to calm stormy waves and guarantee a prosperous voyage. This association with the sea made it a symbol of courage and foresight.
Beyond its nautical connections, aquamarine was also believed to possess healing properties. In ancient Rome, it was thought to cure ailments of the stomach, liver, and throat. Pliny the Elder, the Roman naturalist, wrote that the gem could be ground into a powder to treat eye diseases. During the Middle Ages, it was widely used as an antidote for poison and was believed to rekindle the love between married couples. The gem’s connection to the throat chakra in metaphysical traditions links it to clear communication and self-expression.
The journey of aquamarine to its status as a March birthstone is a more recent development. The modern list of birthstones was standardized in 1912 by the National Association of Jewelers (now Jewelers of America). This list was created to simplify marketing and create a clear guide for consumers. Aquamarine was chosen for March, likely due to its strong color association with the month's transitional, often cool and wet, weather patterns, and its enduring popularity. Its inclusion solidified its place as the primary gem for the month, a position it holds to this day.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its signature blue color coming from trace amounts of iron within its crystal structure. Unlike emeraldes, which get their green color from chromium or vanadium, aquamarine’s color is simpler in origin, resulting in generally higher clarity and fewer inclusions. It forms in large, hexagonal crystals, some of which can be remarkably huge.
The primary geological environment for aquamarine is in igneous rocks, particularly in pegmatites. These are coarse-grained rocks that form during the final stages of a magma chamber's cooling process, allowing for the slow growth of large, well-formed crystals. Hydrothermal processes also play a role, where hot, mineral-rich fluids circulate through cracks in the rock, depositing beryl crystals as they cool.
For centuries, the most significant source of high-quality aquamarine has been Brazil, especially the states of Minas Gerais, Bahia, and Espírito Santo. Brazilian deposits are known for producing large, transparent crystals in a wide range of blue shades. Other notable sources include Pakistan, particularly the Skardu region, which yields intensely blue, often included material; Madagascar, a major producer of both light and dark blue stones; and Mozambique, which is increasingly important for fine quality aquamarine. Minor sources also exist in countries like Tanzania, Kenya, and Zimbabwe.
The mining process often involves both open-pit and underground methods. In pegmatite deposits, miners may follow veins of beryl deep into the earth. Due to the large size of aquamarine crystals, it is not uncommon for single stones to be cut into gems weighing many hundreds of carats. The world's record for a cut aquamarine is held by the "Dom Pedro," a 10,363-carat stone mined in Brazil and now housed in the Smithsonian Institution.
Gemological Properties
Aquamarine is prized by jewelers and collectors not only for its color but also for its excellent physical properties, which make it durable and beautiful for all forms of jewelry. Its defining characteristics are detailed below.
- Color: The most valued color for aquamarine is a deep, saturated blue to a slightly greenish-blue, with strong to medium saturation. Lighter, paler shades are more common and thus more affordable. The color is often described as "watery" or "icy." Unlike some gemstones, aquamarine does not typically exhibit pleochroism (showing different colors from different angles) in a dramatic way.
- Clarity: Aquamarine is classified as a "Type I" gemstone by the GIA, meaning it is typically free of eye-visible inclusions. While some stones may contain needle-like inclusions or tiny cavities, high-quality aquamarine is known for its exceptional clarity. This makes it an ideal gem for large, clean statement pieces.
- Hardness and Durability: On the Mohs scale of hardness, aquamarine scores between 7.5 and 8. This makes it a relatively hard and durable gemstone, resistant to scratching and abrasion in everyday wear. It is suitable for rings, earrings, bracelets, and pendants, though care should be taken to protect it from sharp blows.
- Cut: Because of its clarity and lack of strong pleochroism, aquamarine can be cut into virtually any shape. Common cuts include emerald cuts, oval cuts, pear shapes, and rounds. The large crystal habit allows for the creation of impressive, oversized gems that are often used as centerpieces in jewelry.
- Chemical Composition: As a member of the beryl family, aquamarine has the chemical formula Be₃Al₂Si₆O₁₈. Its blue color is due to trace amounts of iron (Fe²⁺ and Fe³⁺).

Symbolism and Metaphysical Beliefs
Aquamarine has accumulated a rich tapestry of symbolic meanings throughout history. Its primary association is with the sea, which imparts meanings of tranquility, eternal life, and youth. It is considered a stone of courage, calming fears and alleviating stress. For this reason, it is often given as a gift to travelers for protection on long journeys, especially by sea.
In metaphysical circles, aquamarine is closely linked to the throat chakra, the energy center associated with communication. It is believed to help the wearer articulate their truth clearly and compassionately, making it a popular stone for public speakers, teachers, and those in professions requiring clear communication. It is also thought to enhance intuition and spiritual awareness, allowing for a deeper connection to one's inner wisdom.
For those born in March, aquamarine is said to bring feelings of peace, balance, and harmony. It is believed to soothe an overactive mind and calm emotional turbulence, promoting a state of relaxed awareness. It is also associated with marital happiness, a belief that has persisted since the Middle Ages, and is often used to strengthen bonds between partners.
Aquamarine in Gold Jewelry
The combination of aquamarine and gold is a classic pairing in jewelry design. The warm, rich tones of yellow gold create a striking contrast that enhances the cool, serene blue of the gemstone, making it appear even more vibrant. White gold and platinum can also be used for a more modern, monochromatic look that emphasizes the gem's clarity and icy color.
The provided sources for "march birthstone gold jewelry" highlight a significant trend in the modern jewelry market: the use of durable, high-quality, and accessible materials. Several brands are moving away from traditional solid gold and precious gemstones for everyday wear, instead opting for materials like stainless steel with 18K gold plating (using PVD, or Physical Vapor Deposition, process for durability) and high-quality simulants like AAA cubic zirconia.
For example, collections from brands like Kendra Scott feature an "iridescent Light Blue Illusion stone" in their March birthstone-inspired pieces, designed for layering and everyday elegance. Gorjana and Mint & Lily offer similar collections, often emphasizing the versatility of the pieces for daily wear. The focus is on creating jewelry that is both beautiful and practical—waterproof, tarnish-free, and hypoallergenic. This approach makes "birthstone jewelry" an accessible luxury, allowing people to own a meaningful piece without the investment required for fine jewelry. These pieces are often marketed with features like "One Year Warranty" and "Waterproof & Tarnish-Free" guarantees, reflecting a consumer desire for longevity and value.
When aquamarine is set in gold, the design choices often aim to maximize light exposure to the gem. Prong settings are common, allowing the stone to sparkle freely. Bezel settings offer a more secure and modern look, protecting the gem's edges. For larger aquamarine pieces, simple, elegant designs are preferred to let the stone's color be the main focus.
Care and Cleaning
One of the advantages of aquamarine is its relative ease of care, thanks to its good hardness and lack of cleavage. However, proper maintenance will ensure it remains brilliant for generations.
- Routine Cleaning: Aquamarine can be safely cleaned with warm, soapy water and a soft brush. A mild dish soap is sufficient. Be sure to rinse it thoroughly to remove any soap residue, which can create a film on the surface.
- Ultrasonic and Steam Cleaners: Generally, aquamarine is safe for use in an ultrasonic cleaner, provided the stone has no significant fractures or inclusions. It is also typically safe for steam cleaning. However, it is always best to err on the side of caution; if the stone has been treated or has visible inclusions, stick to the warm, soapy water method.
- Avoiding Chemicals and Heat: Like many gemstones, aquamarine should be protected from harsh chemicals, including bleach, chlorine, and strong detergents, which can damage the stone or its setting. Sudden and extreme temperature changes should also be avoided, as they can cause thermal shock and potentially fracture the gem.
- 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.
For jewelry made with plated metals and cubic zirconia, as seen in the modern fashion jewelry market, care instructions are slightly different. While these pieces are often marketed as "waterproof" and "tarnish-free," it is still advisable to avoid prolonged exposure to harsh chemicals like perfume, lotion, and hairspray, which can degrade the plating and dull the crystal over time. Cleaning these pieces with a soft, dry cloth is usually sufficient.
