The month of March is uniquely distinguished in the world of gemstones by its association with not one, but two distinct and historically significant birthstones: Aquamarine and Bloodstone. This duality offers a remarkable spectrum of color and lore, from the serene, oceanic blues of Aquamarine to the earthy, vibrant contrast of Bloodstone. While Aquamarine is the modern primary birthstone, Bloodstone holds a revered place as the traditional alternative, creating a rich tapestry of symbolism for those born in this transitional month. These gemstones, though differing vastly in appearance and composition, share a common narrative of protection, strength, and vitality. This article delves into the geological origins, gemological properties, historical significance, and cultural symbolism of both March birthstones, providing a detailed exploration for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore: From Ancient Seas to Battlefields
The historical journey of the March birthstones is as diverse as their colors. Aquamarine, whose name derives from the Latin words “aqua” (water) and “marina” (sea), has been intrinsically linked to maritime lore for centuries. Ancient mariners believed the gem possessed the power to calm waves and ensure safe passage, making it a talisman for sailors. Beyond its protective qualities at sea, Aquamarine was also thought to bring happiness in marriage and was historically associated with the gemstone beryl, which was believed to grant the wearer protection against foes in battle and litigation. It was also purported to enhance intellect and make the wearer unconquerable and amiable. A notable historical artifact is a dark blue rectangular step-cut Aquamarine weighing 1,298 carats, presented to First Lady Eleanor Roosevelt by the government of Brazil in 1936.
Bloodstone, with its dramatic green and red speckles, carries a lore deeply rooted in courage and vitality. Its name evokes the image of blood, and its symbolism is tied to strength and perseverance. While specific ancient historical accounts from the provided sources are limited, the gem is traditionally associated with courage on the battlefield and is believed to represent strength and vitality. This connection to life force and bravery has made it a symbol of inner strength and detoxification. The existence of two March birthstones stems from the common practice of having both modern and traditional gemstones for each month. Bloodstone predates Aquamarine in traditional lists, but both are now widely accepted and cherished for their unique meanings and beauty.
Geological Formation and Sources
The two March birthstones originate from entirely different mineral families and geological processes, which directly influences their appearance and properties.
Aquamarine is a member of the beryl family, a group of minerals that also includes emeralds and morganite. Its signature blue to blue-green color is derived from trace amounts of ferrous iron within its crystalline structure. As a variety of beryl, Aquamarine forms in pegmatite deposits, which are coarse-grained igneous rocks. Major sources for high-quality Aquamarine include Brazil, Pakistan, Nigeria, Madagascar, and India. The gem is typically found in large, well-formed crystals, which allows for the cutting of sizable, faceted gemstones.
Bloodstone, in contrast, is a variety of chalcedony, which is a cryptocrystalline form of quartz. It is characterized by a deep green base color, caused by chlorite or actinolite inclusions, with distinctive red or orange speckles of iron oxide. These red spots are often referred to as the "blood" within the stone. Bloodstone forms in hydrothermal environments and is often found in nodules or as fillings in volcanic rock. Its primary sources are India, Brazil, Australia, and the United States. Unlike the typically transparent Aquamarine, Bloodstone is almost always cut into cabochons (domed, polished shapes) to best display its rich color contrast and opaque nature.

Aquamarine is prized for its clarity and transparency. High-quality Aquamarine is often "eye-clean," meaning it is free from visible inclusions, symbolizing purity of spirit. Its hardness of 7.5 to 8 on the Mohs scale makes it highly durable and resistant to scratching, rendering it an excellent choice for all types of jewelry, including engagement rings, necklaces, and earrings. Its color ranges from light blue to deep blue, with the most prized specimens exhibiting a clear, bright blue shade. Some stones may display greenish-blue or blue-green tones.
Bloodstone is valued for its opaque, rich coloration. It is typically a dark-green cabochon containing red spots of iron oxide. With a Mohs hardness of 6.5 to 7, it is moderately durable but slightly less hard than Aquamarine. It is important to avoid harsh impacts or abrasive cleaners to prevent chipping or scratching. Its opaque nature makes it unsuitable for faceting; instead, it is cut en cabochon or into beads, showcasing its unique pattern. The contrast between the forest green background and the blood-like red dots creates a bold and distinctive aesthetic.
Symbolism and Metaphysical Beliefs
The symbolic meanings attached to the March birthstones are as vivid as their physical appearance. Both stones are linked to themes of protection and strength, though they express these concepts through different lenses.
Aquamarine is the quintessential stone of serenity, clarity, and communication. Its calming blue hues are believed to reduce stress and bring inner peace. Historically, its association with the sea translates into metaphysical beliefs about enhancing clarity of thought and emotional balance. It is also thought to improve communication skills, making it a popular choice for those who wish to express themselves more effectively. In crystal healing, it is used to soothe anxiety and foster a tranquil state of mind.
Bloodstone embodies courage, vitality, and detoxification. Its earthy, bold appearance is linked to inner strength and perseverance. The red specks, reminiscent of blood, symbolize life force and health. It is traditionally believed to bring bravery to the wearer, making it a talisman for overcoming challenges. Metaphysically, Bloodstone is associated with detoxification, both physical and spiritual, and is thought to purify the body and spirit, enhancing vitality and grounding energy.
Together, these stones offer a complementary set of meanings for March-born individuals: Aquamarine provides calm and clarity, while Bloodstone offers courage and strength. This combination makes the March birthstone collection one of the most diverse and meaningful among all months.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these gemstones, and their differing properties necessitate tailored approaches.
Aquamarine requires relatively straightforward care due to its high hardness and lack of cleavage (a tendency to break along flat planes). It can be cleaned using warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally safe for Aquamarine, but it is always prudent to ensure the stone is free of fractures or inclusions before using these methods. Avoid sudden temperature changes, which could potentially damage the stone.
Bloodstone, with its lower hardness and potential for chipping, demands more gentle handling. Clean it with warm, soapy water and a soft cloth. Avoid ultrasonic cleaners and harsh chemicals, as the vibrations and abrasives could damage the stone or loosen any settings. Due to its opaque nature, it is less likely to show internal flaws, but surface scratches can dull its appearance over time. Store Bloodstone jewelry separately to prevent scratching from harder stones like diamonds or sapphires.
