Introduction
For individuals born in the month of March, two distinct gemstones share the honor of representing their birth: Aquamarine and Bloodstone. These stones, while visually dissimilar, are united by a shared historical reputation for protection and well-being. Aquamarine, with its tranquil blue hues reminiscent of the ocean, is traditionally associated with the zodiac sign Pisces (February 19 – March 20). Bloodstone, a dark green chalcedony flecked with red iron oxide, is linked to the fire sign Aries (March 21 – April 19). The selection of March 7 specifically points to Aquamarine as the primary birthstone for that date, aligning with the Piscean zodiac period. This article explores the geological origins, gemological properties, historical lore, and cultural significance of these two March birthstones, drawing exclusively from authoritative gemological sources.
History and Lore
The history of Aquamarine is deeply rooted in maritime tradition and ancient belief. Its name derives from the Latin words aqua (water) and marina (sea), a direct reference to its oceanic color palette. Ancient mariners held this gemstone in high regard, believing it possessed the power to calm waves and ensure safe passage across treacherous waters. This protective quality was not limited to seafaring; Aquamarine was also thought to offer protection against foes in battle and litigation. Beyond physical safety, the stone was believed to bring happiness in marriage, make the wearer unconquerable and amiable, and quicken the intellect. Its significance extends beyond personal adornment; in 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a dark blue rectangular step-cut Aquamarine weighing 1,298 carats, underscoring its value as a state gift.
Bloodstone, conversely, carries a history centered on vitality and courage. Its traditional significance is described as bravery, strength, and detoxification. While the sources provide less detailed historical narrative for Bloodstone compared to Aquamarine, its reputation is firmly established as a stone of physical fortitude and health.
The journey of these stones into the modern birthstone list is a reflection of evolving traditions. While ancient systems often assigned a single stone per month, contemporary lists, such as those standardized in the 20th century, frequently include multiple options. March is notably blessed with two primary birthstones, symbolizing the dual nature of those born in this month—serenity and strength. Alternative birthstones also exist for March, including Jade (Mystical) and Red Jasper (Ayurvedic), offering further options for those seeking different energies.
Geological Formation and Sources
Aquamarine
Aquamarine is a member of the beryl family, a mineral group that also includes emerald and morganite. It is formed under high-pressure conditions deep within the Earth’s crust. Its distinctive blue to blue-green coloration is the result of trace amounts of iron within its crystal structure. The purest stones are transparent with a light blue tint, a quality highly prized in the jewelry market.
Major sources for high-quality Aquamarine are geologically diverse. Key mining locations include Brazil, Pakistan, Nigeria, Madagascar, and India. These regions are known for producing crystals that can be faceted into large, clear gems suitable for fine jewelry.
Bloodstone
Bloodstone belongs to the chalcedony family, which is a cryptocrystalline form of quartz. It is characterized by its dark green base color, which is punctuated by distinctive red or brown specks of iron oxide. These red spots are the source of its name and its association with blood and vitality.
Bloodstone is mined in several locations worldwide, including India, Brazil, Australia, and the United States. Its formation as a chalcedony typically occurs in volcanic or sedimentary environments, where silica-rich fluids deposit microcrystalline quartz.
Gemological Properties
The physical and optical properties of Aquamarine and Bloodstone differ significantly due to their distinct mineral families. Understanding these properties is crucial for identification, valuation, and care.
Aquamarine Properties
As a beryl, Aquamarine is valued for its hardness, clarity, and color. * Mineral Group: Beryl * Mohs Hardness: 7.5 – 8 (making it a durable gem suitable for everyday wear) * Chemical Composition: Beryllium aluminum cyclosilicate, with iron impurities causing the blue color. * Color Range: Pale blue to greenish-blue. * Clarity: Faceted Aquamarines are often free from inclusions and as clear as water, symbolizing purity of spirit and soul. The purest stones are transparent with a light blue tint.
Bloodstone Properties
Bloodstone, as a cryptocrystalline quartz, has a different set of characteristics. * Mineral Group: Chalcedony (Cryptocrystalline Quartz) * Mohs Hardness: 6.5 – 7 (slightly less hard than Aquamarine but still reasonably durable) * Chemical Composition: Silicon dioxide (SiO₂), with iron oxide inclusions creating the red spots. * Color Range: Dark green with red or brown specks. The "blood" in the stone is the iron oxide that brings health and strength to the wearer according to lore. * Clarity and Cut: Bloodstone is typically cut as a cabochon (a smooth, polished dome) to best display its characteristic color and inclusion patterns. It is not transparent like Aquamarine.

Symbolism and Metaphysical Beliefs
The symbolic meanings of Aquamarine and Bloodstone are as distinct as their appearances, yet both are rooted in the concept of protection.
Aquamarine Symbolism
Aquamarine is the stone of serenity, calmness, and communication. Its association with the water element and the planet Neptune aligns with the intuitive and peaceful nature of the Pisces zodiac sign. Metaphysically, it is believed to: * Promote emotional clarity and peace. * Enhance communication and strengthen relationships. * Offer spiritual protection and awareness. * Balance Aries' fiery energy, making it a versatile stone for those born under that sign as well.
Bloodstone Symbolism
Bloodstone is the stone of courage, passion, and physical strength. Its association with the fire element and the planet Mars aligns with the dynamic and assertive energy of the Aries zodiac sign. Metaphysically, it is believed to: * Boost courage and confidence. * Aid in detoxification and healing. * Enhance vitality and emotional stability. * Provide protection from harm, particularly physical injury.
The dual symbolism of March's birthstones reflects a holistic approach to well-being: Aquamarine governs the mind and spirit, while Bloodstone fortifies the body and will.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone. The differing hardness and chemical composition of Aquamarine and Bloodstone dictate specific cleaning guidelines.
Caring for Aquamarine
With a Mohs hardness of 7.5 to 8, Aquamarine is a relatively hard and durable gemstone. It is resistant to scratching by most materials but can be damaged by sharp blows. It is generally safe to clean Aquamarine jewelry using warm water, a mild dish soap, and a soft brush. Ultrasonic cleaners are typically safe for untreated Aquamarine, but caution is advised for stones that have undergone fracture filling, a common treatment to improve clarity. Steam cleaning is not recommended.
Caring for Bloodstone
Bloodstone, with a Mohs hardness of 6.5 to 7, is slightly softer than Aquamarine and more susceptible to scratching. It is also more porous due to its cryptocrystalline nature. Cleaning should be done gently with warm, soapy water and a soft cloth. Avoid harsh chemicals, acids, and ultrasonic cleaners, as these can damage the stone or affect the iron oxide inclusions. Prolonged exposure to strong sunlight or heat should also be avoided to prevent fading.
Conclusion
Aquamarine and Bloodstone stand as the two celebrated birthstones of March, each offering a unique blend of beauty, history, and symbolism. Aquamarine, the serene blue beryl, connects its wearer to the calming energies of the ocean and promotes clarity and communication. Bloodstone, the courageous chalcedony, provides a link to the fiery spirit of Aries, offering strength, vitality, and protection. Together, they represent the full spectrum of March-born individuals, from the intuitive Pisces to the dynamic Aries. Whether chosen for their gemological properties, historical lore, or metaphysical beliefs, these stones remain enduring symbols of protection and well-being, cherished by gemstone enthusiasts and jewelry buyers alike.
