March is a month of transition, bridging the final days of winter and the hopeful arrival of spring. Reflecting this seasonal duality, the month is uniquely assigned two distinct birthstones: Aquamarine and Bloodstone. While these gems differ significantly in appearance—one embodying the tranquil clarity of the sea and the other the rugged vitality of the earth—they share a profound connection to themes of protection, health, and renewal. The modern standardization of these stones traces back to 1912, when the Jewelers of America formally established the birthstone list. Originally, Bloodstone stood as the sole representative for March, deeply rooted in ancient lore. However, the mid-20th century saw a shift in preference, leading to the addition of Aquamarine in 1952.
The inclusion of a second stone was driven by a desire for greater variety and accessibility within the jewelry market. As Aquamarine gained popularity for its serene blue hues and durability, it offered a contemporary alternative to the darker, more opaque Bloodstone. Today, these two gems offer March-born individuals a choice between a stone associated with clarity and calm and one linked to strength and courage. This article explores the geological origins, gemological properties, rich histories, and symbolic meanings of Aquamarine and Bloodstone, providing a comprehensive guide to the birthstones of March.
The History and Evolution of March’s Birthstones
The tradition of assigning specific gemstones to each month of the year is ancient, originating from the twelve stones found on the breastplate of the High Priest in the biblical Book of Exodus. Over centuries, this religious artifact evolved into the concept of birthstones, though the lists varied by culture and era. The modern, standardized list that is widely recognized today was established in 1912 by the National Association of Jewellers (now known as the Jewelers of America). This 1912 standardization initially designated Bloodstone as the exclusive birthstone for March.
Bloodstone, also known as heliotrope, was chosen for its deep historical roots and symbolic connection to the "rebirth" theme of the spring equinox. Its dark green body color splashed with red iron oxide spots evoked imagery of lifeblood on stone, a powerful symbol of vitality and sacrifice. For decades, it was the primary choice for those born in March.
However, the birthstone list is not immutable. It evolves to reflect changes in availability, consumer preference, and market dynamics. By the early 1950s, the jewelry industry noted a growing demand for a lighter, more versatile gemstone. Aquamarine, a member of the beryl family, had risen in prominence. Its popularity was bolstered by its durability, which made it suitable for a wide range of jewelry, and its captivating color, which was described as "spring's first waters." In 1952, the Jewelers of America officially added Aquamarine to the March birthstone list, creating the dual-birthstone tradition that persists today. This addition provided consumers with a choice: the traditional, rugged strength of Bloodstone or the modern, ethereal elegance of Aquamarine.
Aquamarine: The Primary March Birthstone
Aquamarine is currently regarded as the primary birthstone for March, favored for its durability and widespread appeal. Its name is derived from the Latin words aqua (water) and marina (sea), literally translating to "seawater." This nomenclature perfectly captures the gem's essence, which ranges from a faint, almost colorless blue to a deep, saturated blue-green reminiscent of tropical oceans.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which belongs to the cyclosilicate group. Its chemical formula is Be₃Al₂(SiO₃)₆. The distinct blue to blue-green color is the result of trace amounts of iron ions (Fe²⁺ and Fe³⁺) within the beryl crystal lattice. Beryl forms in pegmatites—coarse-grained igneous rocks—where late-stage, volatile-rich magmatic fluids facilitate the growth of large, well-formed crystals.
The world's most significant deposits of high-quality Aquamarine are found in Brazil. Mines in the states of Minas Gerais and Bahia consistently produce stones with the prized deep blue saturation. Other notable sources include:
- Pakistan: Known for producing crystals with intense color, often found in the Skardu region.
- Madagascar: A major source of both light and deep-blue Aquamarine.
- Nigeria and Mozambique: African sources that yield a significant portion of the global supply.
- United States: Specifically, the state of Colorado has produced Aquamarine, though often in lighter shades.
The sources highlight the discovery of massive crystals, such as the "Presidente Vargas" crystal found in Brazil in 1910, which weighed 243 pounds (approximately 110,000 carats) and yielded 100,000 carats of cut gems. These large, clean crystals allow for the creation of impressive faceted stones and intricate gemstone carvings.
Gemological Properties
Aquamarine is prized by gemologists and jewelers for its excellent physical properties, making it a durable choice for jewelry, particularly rings that are worn daily.
- Hardness: On the Mohs scale of hardness, Aquamarine rates between 7.5 and 8. This makes it resistant to scratching and suitable for everyday wear.
- Clarity: A key characteristic of high-quality Aquamarine is its clarity. It is typically "eye-clean," meaning it is free from visible inclusions. This transparency contributes to its clear, watery appearance and allows light to pass through unimpeded, creating a brilliant sparkle.
- Color: The color is the most critical factor in determining the value of an Aquamarine. The most desirable colors are a deep, saturated blue or a slightly greenish blue. Lighter, paler stones are more common and thus less valuable than their darker counterparts.
- Cut: Because of its clarity and lack of cleavage issues, Aquamarine can be cut into a wide variety of shapes. Faceted cuts are most common to maximize brilliance, but it is also popular for cabochons and carved cameos.
Symbolism and Lore
Aquamarine's history is steeped in maritime lore. Ancient sailors believed the gem had the power to calm waves and protect them from peril at sea. It was considered a talisman of good luck and a safeguard against drowning. Beyond its association with the ocean, Aquamarine was also believed to influence interpersonal relationships. It was thought to bring happiness and longevity to marriages and to foster clear communication and trust between partners.
In the realm of metaphysical beliefs, Aquamarine is associated with the throat chakra, linking it to clear and honest expression. It is often called the "stone of courage," said to soothe fears and reduce stress, allowing the wearer to take on responsibilities with a calm and centered mind. Some lore suggests it quickens the intellect and makes the wearer unconquerable in legal or competitive disputes.
Bloodstone: The Traditional March Birthstone
While Aquamarine is the modern favorite, Bloodstone holds the title of the traditional birthstone for March. Its appearance is starkly different from its counterpart: a dark, opaque green chalcedony (a variety of quartz) speckled with vivid red inclusions of iron oxide or jasper. These red spots, resembling drops of blood, are the source of its name and its powerful symbolism.
Geological Formation and Sources
Bloodstone is a cryptocrystalline form of quartz, with a chemical formula of SiO₂. It forms in volcanic or metamorphic rocks, where silica-rich fluids fill cavities and gradually crystallize over time. The green color comes from embedded chlorite or actinolite minerals, while the red spots are due to iron oxide (hematite).
Unlike Aquamarine, which is often cut into faceted gems, Bloodstone is almost exclusively cut into cabochons (smooth, rounded domes) to best display its unique color patterns and the contrast between the green and red. It is also a popular material for intaglios and cameos due to its ability to be carved.
Significant sources of Bloodstone include:
- India: The primary source for high-quality Bloodstone.
- Australia: Yields substantial deposits of the gem.
- Brazil: Also a notable producer.
- China and the United States: Smaller deposits are found in these regions.
The largest crystals are typically found in India, where it is mined and often cut into beads or cabochons for export.
Gemological Properties
Bloodstone possesses a different set of physical characteristics compared to Aquamarine, reflecting its quartz composition.
- Hardness: On the Mohs scale, Bloodstone ranks as a 6.5 to 7. While still relatively durable, it is softer than Aquamarine and more susceptible to scratching, especially if worn daily in a ring.
- Clarity and Appearance: As an opaque stone, its "clarity" is not judged by transparency but by the vibrancy of its green body color and the distinctness of its red spots. The most prized stones have a deep, rich green background with bright, contrasting red inclusions.
- Cut: The traditional cabochon cut is used to create a smooth surface that highlights the stone's coloration. It is also extensively carved into cameos, intaglios, and decorative objects.
Symbolism and Lore
Bloodstone's lore is rooted in themes of power, vitality, and sacrifice. Its name and appearance led to its association with blood, life force, and courage. In ancient times, it was believed to have healing properties, particularly for blood-related ailments. It was said to stop bleeding, purify the blood, and detoxify the body.
The stone carries a strong association with nobility and sacrifice. Legend holds that Bloodstone was formed at the crucifixion of Christ, where the blood from his wounds dripped onto the green stone at the foot of the cross. This Christian lore cemented its reputation as a stone of martyrdom and noble sacrifice. In medieval Europe, it was used by soldiers as a talisman to protect against injury and to staunch wounds.
Beyond its protective qualities, Bloodstone is a symbol of rebirth and renewal, fitting for its status as a March birthstone. It is believed to bring strength, resilience, and the vitality needed to overcome challenges. For those born in March, it serves as a grounding force, connecting them to the enduring power of the earth.
Comparing the Two Stones: A Choice for the March-Born
The dual nature of March's birthstones offers a unique choice for individuals born in the month. The decision between Aquamarine and Bloodstone often comes down to personal style, lifestyle, and the symbolic meaning that resonates most.

Care and Maintenance
Proper care is essential to preserve the beauty and integrity of any gemstone. Due to their differing hardness and structural properties, Aquamarine and Bloodstone require distinct cleaning and storage methods.
Caring for Aquamarine
Thanks to its high hardness and lack of cleavage, Aquamarine is a relatively low-maintenance gemstone.
- Cleaning: It can be safely cleaned using warm water, a mild soap (like dish soap), and a soft brush (such as a toothbrush). Be sure to rinse it thoroughly to remove any soap residue. Ultrasonic and steam cleaners are generally safe for Aquamarine, provided the stone does not have any fractures or significant inclusions.
- Storage: Store Aquamarine separately from other jewelry to prevent it from scratching softer stones. While it is hard, it can still be chipped by harder gems like diamonds or sapphires.
- Considerations: Prolonged exposure to high heat or sudden temperature changes can alter the stone's color, so it is best to keep it away from extreme environments.
Caring for Bloodstone
As a member of the quartz family with a lower hardness rating, Bloodstone requires more careful handling.
- Cleaning: The safest method is to use warm, soapy water and a soft cloth. Avoid harsh chemicals, bleach, and household cleaners, as the porous nature of the stone can absorb these substances, potentially damaging its surface or altering its color.
- Storage: Bloodstone should be stored in a soft pouch or a separate compartment in a jewelry box to prevent it from being scratched by harder materials.
- Considerations: Avoid exposing Bloodstone to extreme temperatures or prolonged sunlight, which could cause the red iron oxide spots to fade over time. Due to its relative softness, it is not recommended for daily-wear rings unless the setting is protective (e.g., bezel-set).
