The month of March is uniquely represented by two distinct yet complementary gemstones: the serene, oceanic Aquamarine and the resilient, earthy Bloodstone. These stones, one a gem of the sea and the other a talisman of strength, offer a fascinating study in contrast, history, and gemological diversity. As the primary modern birthstone, Aquamarine is celebrated for its tranquil blue hues and remarkable clarity, belonging to the esteemed beryl family. Its alternative, Bloodstone, a member of the quartz family, carries a deep, opaque green marked by vivid red flecks, evoking a sense of ancient power and vitality. Both stones share a long-standing reputation for safeguarding the wearer, though they draw their symbolism from vastly different realms of nature. This article explores the rich history, geological origins, gemological properties, and symbolic meanings of these two March birthstones, providing a comprehensive guide for enthusiasts, collectors, and anyone captivated by the lore of gemstones.
The Dual Legacy: History and Lore of March's Gems
The historical journey of March's birthstones is a tale of two distinct paths, one charted by mariners on the open sea and the other by warriors and healers on the battlefield. The association of these stones with the month of March has evolved over centuries, reflecting a blend of ancient tradition and modern standardization.
Aquamarine: The Sailor's Talisman
Aquamarine's history is intrinsically linked to the sea, a connection made literal by its name, which derives from the Latin words aqua marina, meaning "water of the sea." This etymology is not merely descriptive; it is the foundation of the gem's historical lore. Ancient mariners believed the gem was a treasure of mermaids and wore it as a powerful talisman for protection. They claimed that Aquamarine had the power to calm waves and ensure a safe passage, guarding against the perils of a stormy ocean. Beyond its nautical protective qualities, the stone was also thought to bring happiness in marriage and was a symbol of love and affection.
The lore of Aquamarine extends beyond the maritime world into the realm of conflict. As a member of the beryl family, which also includes emerald, it was believed in ancient times to grant the wearer protection against foes in both battle and litigation. The stone was said to make the wearer unconquerable, amiable, and intellectually quickened. This broad spectrum of protective powers—from the dangers of the sea to the complexities of legal disputes and warfare—cemented Aquamarine's status as a highly prized amulet in the ancient world.
Bloodstone: The Martyr's Stone
In contrast, the history of Bloodstone is rooted in terrestrial power and Christian martyrdom. Also known as heliotrope, this dark green chalcedony is characterized by its distinctive red spots of iron oxide, which were poetically interpreted as the blood of Christ. This association gave rise to one of its most enduring names, "the martyr's stone." Legend holds that during the crucifixion, the blood of Christ fell upon a piece of green jasper, creating the first Bloodstone and imbuing it with sacred significance.
This religious connection fostered a belief in Bloodstone's ability to grant invisibility, a power sought by those in peril. Its reputation for strength and vitality was so profound that it was believed to staunch bleeding and cure blood-related ailments, a classic example of the "doctrine of signatures" where a stone's appearance is thought to indicate its function. Bloodstone was carried as a charm for health, strength, and longevity, and was thought to bestow courage and wisdom upon its owner.
The Modern Birthstone List
The formalization of these stones as March's birthstones is a more recent development. The concept of birthstones has ancient roots, with connections to the Breastplate of Aaron described in the Book of Exodus, which featured twelve gems representing the twelve tribes of Israel. Over time, this tradition evolved, and by the 18th century, a specific list of birthstones for each month had become popular in Poland and spread throughout Europe.
In 1912, the National Association of Jewelers (now Jewelers of America) in the United States convened to standardize this list for commercial purposes. This meeting, known as the "birthstone list of 1912," established Aquamarine as the official birthstone for March. Bloodstone, which had been the primary March stone in many older lists, was relegated to an "alternative" or traditional status. This decision was likely influenced by Aquamarine's growing popularity in the jewelry market due to its beauty and clarity. Today, both stones are widely recognized, offering those born in March a choice between a classic, luminous gem and a historic, powerful one.
Geological Formation and Mining Sources
The contrasting appearances of Aquamarine and Bloodstone are a direct result of their different geological origins and chemical compositions. One is a large, transparent crystal formed in igneous rock, while the other is a microcrystalline variety of quartz formed in volcanic or sedimentary environments.
Aquamarine: A Beryl of Pegmatites
Aquamarine is a variety of the mineral beryl, which has the chemical formula Be₃Al₂(SiO₃)₆. Its characteristic blue-to-blue-green color is caused by trace amounts of ferrous iron (Fe²⁺) within its crystal lattice. Unlike emerald, which gets its green color from chromium or vanadium, Aquamarine's color is subtler and more stable. The finest gems exhibit a pure, saturated blue to a slightly greenish blue, with the most prized specimens displaying a deep, intense blue. However, the majority of commercial Aquamarine is found in light blue to very pale shades, often so pale as to be nearly transparent.
This gemstone forms in large hexagonal crystals, often found in pegmatites. Pegmatites are exceptionally coarse-grained igneous rocks that form during the final stages of a magma chamber's cooling process. This environment allows for the growth of enormous crystals, and Aquamarine is known for producing spectacularly large, flawless specimens. The famous 1,298-carat aquamarine given to First Lady Eleanor Roosevelt by the government of Brazil in 1936 is a testament to the gem's potential for size and clarity.
Brazil is the world's foremost source of high-quality Aquamarine, particularly from the states of Minas Gerais and Bahia. Other significant mining locations include: * Pakistan: Known for its vibrant, deep blue crystals from the Shigar Valley. * Madagascar: Produces a range of colors and sizes. * Mozambique and Tanzania: Also important sources in Africa. * United States: Notably, the state of North Carolina has produced fine Aquamarine crystals.
Bloodstone: A Variety of Chalcedony
Bloodstone, or heliotrope, is a cryptocrystalline variety of quartz, composed of silicon dioxide (SiO₂). Its chemical formula is the same as that of amethyst, citrine, and jasper, but its fine-grained, opaque nature gives it a completely different character. Bloodstone consists of dark green chalcedony, which is a fibrous form of quartz, with inclusions of red iron oxide (hematite). These red spots, which resemble drops of blood, are the defining feature of the gem. The base color is typically a deep, earthy green, providing a stark and beautiful contrast to the bright red speckles.
Bloodstone is not typically found in large, crystalline veins like Aquamarine. Instead, it forms in nodules or as fillings in cracks of other rocks, often in volcanic or sedimentary environments. Its sources are more widespread and less concentrated than those of high-grade Aquamarine.
Major sources for Bloodstone include: * India: The primary source for high-quality Bloodstone, often used in cameos and intaglios. * Brazil: A significant producer of many gemstones, including Bloodstone. * Australia: Also a notable source of this gemstone. * China, Germany, and the United States: Have also produced Bloodstone, though often of lower commercial quality.

Aquamarine's Profile: Aquamarine is prized for its excellent hardness of 7.5 to 8 on the Mohs scale, making it quite resistant to scratching and suitable for all types of jewelry, including daily-wear rings. Its vitreous luster and high clarity are defining features. As noted by the Gemological Institute of America (GIA), faceted aquamarines are often free from inclusions and "as clear as water." This transparency allows light to pass through easily, resulting in a brilliant sparkle when cut. The gem is typically cut into classic shapes like emerald cuts, ovals, and rounds to maximize its color and clarity.
Bloodstone's Profile: Bloodstone, with a Mohs hardness of 6.5 to 7, is slightly softer than Aquamarine but still durable enough for most jewelry applications, especially in protective settings like bezels. Its key characteristic is its opacity. It does not allow light to pass through and therefore is not faceted. Instead, Bloodstone is almost exclusively cut en cabochon (a smooth, rounded dome) or carved into intaglios, cameos, and beads. This cutting style best showcases its rich green color and the dramatic pattern of its red spots. Its luster is typically vitreous but can appear waxy due to its translucence.
Symbolism and Metaphysical Beliefs
Across cultures and through the centuries, both Aquamarine and Bloodstone have been ascribed powerful metaphysical properties, reflecting their natural characteristics.
Aquamarine is the quintessential stone of tranquility, courage, and communication. Its connection to the sea fosters beliefs in its ability to calm emotional turmoil, reduce stress, and soothe anxiety. It is known as the "stone of courage," thought to bolster the confidence of speakers, performers, and anyone who must speak in public. In relationships, it symbolizes trust, loyalty, and harmony, making it a popular gift to reaffirm love and commitment. Its calming energy is also believed to enhance intuitive awareness and provide mental clarity.
Bloodstone is the embodiment of strength, vitality, and protection. It is known as a powerful grounding stone that revitalizes and energizes the physical body. Its association with blood links it to life force, circulation, and overall health, and it is often used in healing rituals. Bloodstone is believed to instill courage, wisdom, and a willingness to sacrifice for a noble cause. It is a talisman for those in demanding situations, providing resilience and the strength to overcome adversity. Spiritually, it is said to absorb negative energy and protect the wearer from psychic attack and manipulation.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone. The differing hardness and clarity of Aquamarine and Bloodstone dictate specific cleaning methods.
Aquamarine Care: Thanks to its high hardness and excellent clarity, Aquamarine is relatively easy to care for. * Cleaning: The safest method is warm, soapy water with a soft brush. Rinse thoroughly to remove any soap residue. Ultrasonic and steam cleaners are generally safe for untreated and unheated stones, but caution is advised if the stone has been fracture-filled (though this is rare for Aquamarine). * Storage: Store it separately from other jewelry to prevent it from scratching softer gems or being scratched by harder stones like diamonds.
Bloodstone Care: Bloodstone's opacity and lower hardness require more gentle handling. * Cleaning: Use warm, soapy water and a soft cloth or brush. Avoid harsh chemicals and strong detergents, which can dull its surface. Do not use an ultrasonic cleaner, as the vibrations could potentially damage the stone or loosen any settings. Steam cleaning is also not recommended. * Storage: Store it in a soft pouch or a separate compartment in your jewelry box to prevent scratches. Given its potential for fracturing due to its cryptocrystalline nature, protect it from hard impacts.
