Introduction
For those born on March 20, aquamarine is not just a birthstone—it is a personal talisman that reflects their connection to the sea and the sky. As the principal March 20 birthstone, aquamarine is deeply linked to the zodiac sign Pisces, which spans from February 20 to March 20. Alongside aquamarine, bloodstone is also recognized as an official March birthstone, offering a contrasting yet equally meaningful presence. Together, these two gemstones embody the duality of March, a month of transition from winter to spring, and symbolize the themes of renewal, growth, and transformation.
This article explores aquamarine in detail, covering its geological formation, historical significance, cultural associations, and practical care. It also introduces bloodstone as an alternative March birthstone, providing a comprehensive overview of the gemstone options for those born in this dynamic month.
History and Lore
Ancient Beliefs and Early Use
Aquamarine’s history stretches back to ancient times, with early civilizations attributing powerful properties to the gemstone. One of the most enduring legends is that aquamarine was believed to protect sailors on their journeys. Ancient mariners carried aquamarine to calm the seas and ensure safe passage, a belief rooted in its tranquil blue color, which resembles the ocean. This association with the sea earned the gemstone its name, derived from the Latin phrase aqua marina, meaning "water of the sea."
In addition to its maritime connections, aquamarine was also used in ancient Greece and Rome for its perceived medicinal and spiritual properties. It was believed to promote courage and protect against poisoning, making it a favored gemstone among rulers and warriors. The Romans, in particular, valued aquamarine for its calming effects and often used it in jewelry to symbolize serenity and strength.
Transition to Modern Birthstone Traditions
The concept of birthstones can be traced back to biblical times, particularly to the 12 stones described in the breastplate of the High Priest Aaron in the Book of Exodus. Over time, these stones were associated with the months of the year, and by the first century AD, early birthstone lists were being compiled. However, it was not until the 16th century that people began wearing birthstones corresponding to their own birth months. This practice is believed to have originated with jewelers in Germany and Poland, who started selling birthstone jewelry during this period.
The standardized birthstone list we recognize today began to take shape in the 1800s. One of the key contributors to this standardization was the jewelry house Tiffany & Co., which helped popularize the association of specific gemstones with each month. In the case of March, aquamarine and bloodstone were officially recognized as the dual birthstones, a practice that continues to this day.
March itself has a rich historical context. Named after the Roman god of war, Mars, it was considered the beginning of the year in the ancient Roman calendar. The month was marked by the resumption of military campaigns after the winter pause, as well as the start of the spring planting season. With the spring equinox occurring on March 20 in the Northern Hemisphere, the month became a symbol of new beginnings and the promise of the future.
In modern times, March is also a month of celebration for equality and progress. It is recognized as Women’s History Month, with International Women’s Day on March 8 serving as a global acknowledgment of the achievements and contributions of women. This adds a contemporary layer of significance to the birthstones of March, particularly aquamarine and bloodstone.
Geological Formation and Sources
Composition and Formation
Aquamarine is a member of the beryl family, a group of silicate minerals that includes emerald, another well-known beryl variant. The difference between aquamarine and emerald lies in the trace elements that give them their distinct colors. While emerald owes its deep green to chromium or vanadium, aquamarine derives its blue color from trace amounts of ferrous iron (Fe²⁺). This subtle difference in composition results in a gemstone that is both visually striking and scientifically fascinating.
Aquamarine forms in pegmatite deposits, which are coarse-grained igneous rocks that develop from the slow cooling of magma. These deposits are rich in rare elements and provide the ideal environment for the growth of large, well-formed crystals. The conditions required for aquamarine formation include high temperatures and the presence of water-rich fluids, which facilitate the crystallization process.
Mining Locations
Aquamarine is found in several parts of the world, with the most significant sources located in South America, particularly in Brazil, Nigeria, and Madagascar. Brazil, in particular, is known for producing high-quality aquamarine, with the state of Minas Gerais being a major mining region. The gemstone is also found in the United States, Russia, and China, though the Brazilian deposits are generally considered the most prolific.
Bloodstone, the other official March birthstone, is a form of chalcedony that gets its name from the red spots that resemble drops of blood. These spots are caused by inclusions of iron oxide, which give the stone its distinctive appearance. Bloodstone is typically found in India, Brazil, and the United States, with India being the largest producer. It forms in volcanic rock and is often mined in deposits that have been exposed to weathering and erosion.
The contrasting geological origins of aquamarine and bloodstone highlight the diversity of gemstones that can be associated with a single month. While aquamarine is a transparent, crystalline gem formed in pegmatites, bloodstone is an opaque, cryptocrystalline stone that forms in volcanic rock. This duality makes the March birthstones both visually and geologically unique.
Gemological Properties
Color and Clarity
Aquamarine is known for its beautiful blue tones, which can range from pale, almost colorless blue to deep, rich shades. The most prized aquamarine stones are those with a medium to dark blue color, as they display the best balance of hue and brilliance. The color is influenced by the concentration of iron in the crystal, with higher concentrations producing deeper blues. Stones with a more greenish tint are sometimes referred to as "green beryl" and are generally less valuable.
In terms of clarity, aquamarine is typically included, with visible inclusions being a common feature of the gemstone. These inclusions are usually not considered flaws but rather a natural part of the stone’s character. High-quality aquamarine is transparent or slightly translucent, allowing light to pass through and create a pleasing sparkle.
Hardness and Durability
On the Mohs scale of mineral hardness, aquamarine ranks between 7.5 and 8, making it a relatively durable gemstone that is suitable for everyday wear. This hardness level means that aquamarine can withstand normal wear and tear without easily scratching or chipping. However, it is still important to handle aquamarine jewelry with care, as it can be damaged if subjected to impact or abrasion.
Aquamarine does not have cleavage, which means it does not break along specific planes, but it does have a tendency to fracture if struck at the right angle. This makes it important to avoid subjecting the gemstone to high-impact situations, such as dropping it on a hard surface or wearing it during activities that could result in physical trauma.
Cut and Shape
Aquamarine is most commonly cut in a brilliant or step cut to enhance its color and clarity. The brilliant cut, with its many facets, helps to maximize the gemstone’s sparkle, while the step cut is designed to emphasize the color and clarity of the stone. Aquamarine is also popular in mixed cuts, which combine both brilliant and step cuts to create a unique visual effect.
In terms of shape, aquamarine is often cut into traditional gemstone shapes such as rounds, ovals, cushions, and emerald cuts. The oval and emerald cuts are particularly popular for aquamarine, as they allow the gemstone to showcase its deep blue color and clarity. Aquamarine is also used in more modern or artistic cuts, which can create a one-of-a-kind look for custom jewelry pieces.
Symbolism and Metaphysical Beliefs
Spiritual and Emotional Properties
Aquamarine has long been associated with calming and soothing properties, making it a popular choice for those seeking emotional balance and inner peace. In spiritual practices, aquamarine is believed to resonate with the throat and heart chakras, promoting clear communication and emotional healing. It is often used in meditation to help release fear, anxiety, and stress, allowing the wearer to feel more centered and at ease.
One of the most well-known metaphysical properties of aquamarine is its association with courage and strength. It is believed to help individuals overcome their fears and speak their truth with confidence. This makes it a particularly powerful gemstone for those who struggle with public speaking or expressing themselves in social situations. Aquamarine is also thought to promote trust and loyalty in relationships, making it a meaningful stone for couples and friends.
Historical and Cultural Symbolism
Throughout history, aquamarine has been used as a symbol of protection and good fortune. In ancient times, it was believed to shield the wearer from harm and ensure a safe journey across the sea. Sailors and explorers often carried aquamarine with them on their voyages, believing that the gemstone would calm the waters and protect them from the dangers of the ocean.
In addition to its maritime associations, aquamarine has also been used in royalty and high society for centuries. It was a favorite gemstone among European nobility, who believed that it brought wisdom and clarity to those who wore it. In some cultures, aquamarine was also believed to promote longevity and good health, making it a popular choice for amulets and protective charms.
Bloodstone, as the alternative March birthstone, carries its own set of symbolic meanings. Known for its deep green color and red inclusions, bloodstone is associated with strength, endurance, and vitality. In ancient Greece and Rome, it was used as a protective stone for warriors, believed to enhance courage and promote physical endurance. Bloodstone is also associated with the root chakra, offering grounding and protection for the wearer.
Care and Cleaning
Proper Maintenance
To keep aquamarine in optimal condition, it is important to handle it with care and clean it regularly. Aquamarine is relatively durable, but it can still be damaged if exposed to harsh chemicals, extreme temperatures, or physical impact. It is recommended to clean aquamarine with a soft cloth and mild soapy water, using a soft-bristled brush to gently remove any dirt or debris.
Aquamarine should not be exposed to ultrasonic or steam cleaners, as these can cause damage to the gemstone or the jewelry setting. It is also important to avoid exposing aquamarine to prolonged sunlight, as this can cause the color to fade over time. If aquamarine is being stored for an extended period, it should be kept in a cool, dry place to prevent any changes in color or clarity.
Professional Inspection
For those who wear aquamarine jewelry frequently, it is a good idea to have the gemstone professionally cleaned and inspected periodically. A professional jeweler can ensure that the stone is free from damage and that the setting is secure. This is especially important for aquamarine jewelry that is worn on a daily basis, as the gemstone can be subjected to normal wear and tear over time.
Bloodstone requires similar care to aquamarine, as it is also a durable gemstone that can withstand regular use. However, it is important to avoid exposing bloodstone to harsh chemicals or abrasive materials, as this can damage the surface of the stone. Bloodstone can be cleaned with a soft cloth and mild soapy water, and it is best to avoid using steam or ultrasonic cleaners.
