The month of March is uniquely associated with two gemstones of strikingly different appearances and lore: Aquamarine and Bloodstone. While Aquamarine is celebrated for its serene, oceanic hues, Bloodstone is defined by its deep green canvas splashed with red speckles. Together, they offer a remarkable duality, representing the calm and the courageous, the tranquil and the vital. This article delves into the history, geological origins, gemological properties, and cultural significance of both March birthstones, providing a comprehensive guide for enthusiasts, collectors, and those born in the third month of the year.
History and Lore
The historical narratives of Aquamarine and Bloodstone are as distinct as their colors, each carrying centuries of symbolism and belief.
Aquamarine, whose name derives from the Latin aqua marina meaning "seawater," has long been intrinsically linked to the ocean. Ancient mariners believed the gem possessed the power to calm waves and protect sailors from danger at sea, making it a cherished talisman for voyages. Beyond its nautical associations, Aquamarine was also thought to bring happiness in marriage and offer protection against foes in both battle and litigation. Beliefs held that the stone could make the wearer unconquerable, amiable, and intellectually quicker. Its historical value is underscored by notable gifts, such as the dark blue rectangular step-cut aquamarine weighing 1,298 carats given by the Brazilian government to First Lady Eleanor Roosevelt in 1936. Furthermore, Aquamarine is designated as a gift for the 19th wedding anniversary, cementing its place in modern sentimental traditions.
In contrast, Bloodstone carries a more terrestrial and martial legacy. Its lore is deeply rooted in themes of strength, vitality, and courage. The stone’s distinctive red speckles, which are spots of iron oxide, were historically interpreted as the "blood" of Christ or a symbol of life force, leading to its reputation for bringing health and strength to the wearer. Bloodstone was associated with courage on the battlefield and was believed to possess properties that could enhance physical endurance and vitality. While both stones share a reputation for protection, Aquamarine’s guardianship was focused on safe passage and emotional clarity, whereas Bloodstone’s was centered on physical fortitude and resilience.
Geological Formation and Sources
Understanding the origins of these gemstones reveals the natural processes that create their unique characteristics.
Aquamarine is a member of the beryl mineral family, which also includes emerald and morganite. Its blue coloration is primarily due to trace amounts of iron within its crystalline structure. High-quality Aquamarine is prized for its clarity and transparency, often appearing "as clear as water." Major sources for this gemstone include Brazil, Madagascar, Nigeria, and the United States, as indicated in the provided materials. The gem's formation typically occurs in pegmatite veins, where beryl crystals can grow to substantial sizes, allowing for the extraction of large, facetable rough.
Bloodstone, also known as heliotrope, is a variety of chalcedony, which is a microcrystalline form of quartz. It is characterized by its dark green base color, which is often opaque, and the distinctive red or orange speckles of iron oxide that give it its name. Unlike the transparent Aquamarine, Bloodstone is typically cut into cabochons or beads to best showcase its patterned surface. While specific mining locations are not detailed in the provided sources, the material notes that high-quality Bloodstone is sought after, though it is generally more affordable and commonly available than premium Aquamarine.
Gemological Properties
The scientific properties of Aquamarine and Bloodstone dictate their durability, appearance, and care requirements.
Aquamarine is a relatively hard and durable gemstone, scoring between 7.5 and 8 on the Mohs scale of hardness. This makes it an excellent choice for jewelry that is worn daily, such as engagement rings, earrings, and necklaces. Its crystal structure is trigonal, and it possesses a glassy luster. The color range for Aquamarine spans from pale, light blue to deep oceanic blue, sometimes with subtle greenish undertones. The most valued specimens are those with a clear, bright blue hue and excellent transparency, free from significant inclusions.
Bloodstone is also durable, with a hardness of approximately 6.5 to 7 on the Mohs scale, making it suitable for various jewelry applications, though it requires slightly more care than Aquamarine. It is an opaque gemstone with a waxy luster. Its defining feature is the contrast between its dark green chalcedony base and the red iron oxide inclusions. The quality of Bloodstone is often judged by the intensity and distribution of these red spots against the green background.

Symbolism and Metaphysical Beliefs
Beyond their physical beauty, both March birthstones are rich in symbolic meaning and are frequently used in crystal healing and metaphysical practices.
Aquamarine is widely regarded as a stone of serenity, courage, and clarity. It is believed to enhance communication, reduce stress, and promote inner peace. As a protective stone for travelers, it is often associated with emotional balance and the calming of anxiety. Its connection to the sea reinforces its symbolism of flow, intuition, and emotional release.
Bloodstone symbolizes strength, vitality, and endurance. In metaphysical beliefs, it is thought to support physical strength, enhance circulation, detoxify the body, and boost the immune system. It is often associated with courage, particularly in overcoming obstacles and enduring challenging situations. The "blood" in the stone is linked to life force and vitality, making it a popular stone for those seeking to increase their energy and resilience.
Both stones are believed to possess protective qualities, though they are applied to different aspects of well-being—Aquamarine for emotional and spiritual safety, and Bloodstone for physical and practical strength.
Care and Cleaning
Proper maintenance is essential to preserve the beauty and longevity of these gemstones, and their differing properties necessitate specific care protocols.
Aquamarine, with its higher hardness (7.5-8), is quite resilient but should still be handled with care. The recommended cleaning method is using mild soap and warm water. It is important to avoid exposure to harsh chemicals, which can damage the stone or its setting. Ultrasonic and steam cleaners are generally safe for untreated Aquamarine, but caution is advised if the stone has been fracture-filled or treated. Storing Aquamarine jewelry separately is advisable to prevent scratching from harder gems like diamonds or sapphires.
Bloodstone, being a variety of quartz, is also durable but has a slightly lower hardness. The sources recommend wiping it with a damp cloth for cleaning. For a deeper clean, warm soapy water and a soft brush can be used, but it should be rinsed thoroughly and dried. As with Aquamarine, exposure to harsh chemicals should be avoided. Given its opaque nature and typical cabochon cut, it is less likely to show surface scratches than a faceted stone, but it should still be stored separately to prevent abrasion from other jewelry.
Conclusion
Aquamarine and Bloodstone offer a compelling study in contrasts, yet both are profoundly connected to the month of March. Aquamarine, with its tranquil blue hues and historical ties to the sea, embodies serenity, clarity, and protection. Bloodstone, with its earthy green base and vibrant red speckles, represents strength, vitality, and courage. Their distinct gemological profiles—Aquamarine as a hard, transparent beryl and Bloodstone as an opaque, patterned chalcedony—make them suitable for a wide range of jewelry styles, from elegant faceted rings to bold, cabochon-set pieces. Whether chosen for their beauty, historical significance, or metaphysical properties, Aquamarine and Bloodstone remain enduring and meaningful birthstones for those born in March.
