The month of March is uniquely distinguished in the world of gemology by its two official birthstones: Aquamarine and Bloodstone. These stones, vastly different in appearance and lore, represent the dual nature often associated with those born in this transitional month, influenced by the zodiac signs of Pisces and Aries. While Aquamarine is celebrated for its serene, oceanic blue hues, Bloodstone commands attention with its deep green matrix flecked with red iron oxide. Both stones have traversed a long history, deeply embedded in ancient lore, maritime tradition, and the annals of geological science.
The significance of these gems extends beyond mere aesthetics. For centuries, they have been attributed with potent metaphysical properties, ranging from protection against physical harm to the enhancement of mental clarity. As the primary birthstones for March, they offer a rich field of study for gem enthusiasts, collectors, and those interested in the cultural history of minerals. This article explores the geological origins, gemological properties, historical narratives, and symbolic meanings of Aquamarine and Bloodstone, drawing upon established gemological research and historical records to present a comprehensive overview of March’s captivating birthstones.
Aquamarine: The Sailor’s Gem
Aquamarine, the most recognized birthstone for March, belongs to the beryl family, the same mineral group that includes the emerald. Its name is derived from the Latin words aqua (water) and marina (sea), a direct reference to the stone’s distinctive color palette, which ranges from deep green-blue to light, slightly greenish blue hues. This connection to the sea is not merely linguistic; it is deeply rooted in the stone’s history and the beliefs surrounding it.
History and Lore
The history of Aquamarine is as deep and varied as the waters it resembles. Ancient mariners believed the gem was a talisman of good luck and protection. They claimed that Aquamarine, when worn, would calm waves and keep sailors safe during treacherous voyages. This belief in its protective power extended beyond the high seas. In ancient Rome and Greece, the stone was valued not only for its beauty but also for its perceived ability to protect against foes in battle and litigation. It was thought to make the wearer unconquerable, amiable, and intellectually quickened.
The stone’s association with happiness in marriage is another historical facet, leading to its designation as a gift for the 19th wedding anniversary. The allure of Aquamarine has captivated historical figures as well. In 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a dark blue, rectangular step-cut Aquamarine weighing an impressive 1,298 carats, a testament to the stone’s prestige and visual impact.
Geological Formation and Sources
Aquamarine forms in hexagonal crystals within igneous rocks known as pegmatites. These large crystals can grow to substantial sizes, allowing for the cutting of significant gemstones. The blue color is attributed to trace amounts of iron within the beryl crystal structure.
While Aquamarine is found in various locations globally, the finest quality stones are historically associated with Brazil. However, significant deposits are also sourced from other regions. According to gemological trade sources, the best sources for high-quality Aquamarine currently include Brazil, Madagascar, and Nigeria. These locations produce stones that exhibit the clear, bright blue shade with excellent transparency that is most prized in the market.
Gemological Properties
Aquamarine is highly valued in the jewelry industry not just for its color but for its durability. As a member of the beryl family, it possesses a hardness of 7.5 to 8 on the Mohs scale, making it resistant to scratching and suitable for various types of jewelry, including engagement rings, necklaces, and earrings. This durability is a key factor in its popularity for fine jewelry.
Key properties of Aquamarine include: * Mineral Group: Beryl * Chemical Composition: Be3Al2Si6O18 (Beryllium Aluminum Silicate) with Iron (Fe) impurities causing color. * Hardness (Mohs Scale): 7.5 – 8 * Crystal System: Hexagonal * Refractive Index: 1.577 – 1.583 (±0.005) * Specific Gravity: 2.68 – 2.71 * Clarity: Faceted Aquamarines are often free from inclusions and as clear as water, symbolizing purity of spirit and soul. Eye-clean specimens are common in the market.
Bloodstone: The Warrior’s Talisman
Standing in stark contrast to the translucent blue of Aquamarine is Bloodstone, the secondary birthstone for March. Also known as Heliotrope, Bloodstone is an opaque variety of Chalcedony, a microcrystalline form of Quartz. It is typically dark green in color, distinguished by distinct red or orange speckles caused by inclusions of iron oxide (specifically, Hematite). This striking contrast gives the stone its evocative name and rich, earthy aesthetic.
History and Lore
Bloodstone carries a history steeped in symbolism related to life, vitality, and courage. Its lore is often more visceral and martial than that of Aquamarine. The red spots were historically viewed as the "blood" of the earth, imbuing the stone with the power to bring health and strength to the wearer.
In ancient times, Bloodstone was a popular amulet for warriors. It was believed to staunch wounds and prevent injury, acting as a shield in battle. Its association with strength and vitality made it a symbol of courage and resilience. This reputation for protecting one's well-being is a shared characteristic with Aquamarine, though the mechanisms of protection differ—one for the dangers of the sea, the other for the violence of the battlefield.
Geological Formation and Sources
Bloodstone is a variety of quartz, composed primarily of silicon dioxide. It forms in massive structures rather than distinct crystals, which is why it is typically cut into cabochons (domed, polished stones) rather than faceted gems. The red spots are inclusions of hematite or jasper that occurred during the stone's formation.
Sources for Bloodstone are widespread. While not as rare as high-quality Aquamarine, fine specimens with vivid green color and distinct red spotting are highly sought after. Reputable sources for Bloodstone include India, Brazil, Australia, China, and parts of Africa.
Gemological Properties
Bloodstone is valued for its durability and unique appearance. As a variety of quartz, it has a hardness of 6.5 to 7 on the Mohs scale. While slightly softer than Aquamarine, it is still durable enough for jewelry, particularly in styles like signet rings, bracelets, and cabochon pendants where its opaque nature can be best displayed.
Key properties of Bloodstone include: * Mineral Group: Chalcedony (Cryptocrystalline Quartz) * Chemical Composition: SiO2 (Silicon Dioxide) with inclusions of Hematite. * Hardness (Mohs Scale): 6.5 – 7 * Crystal System: Trigonal (Microcrystalline) * Luster: Vitreous to waxy. * Transparency: Opaque. * Specific Gravity: 2.58 – 2.64

The allure of March’s birthstones is amplified by their rich symbolism and enduring metaphysical beliefs. These beliefs, passed down through generations, continue to resonate with modern crystal healers and those who ascribe to the lore of gemstones.
The Dual Nature of March
The pairing of Aquamarine and Bloodstone reflects the duality of March itself—a month that bridges the harshness of winter and the renewal of spring. Aquamarine embodies the calm, intuitive, and fluid nature associated with the zodiac sign Pisces. Its energy is cooling, calming, and communicative. It is believed to reduce stress, soothe the emotions, and enhance clarity of thought and spiritual awareness.
Conversely, Bloodstone represents the fiery, assertive, and dynamic energy of Aries. It is a stone of endurance, physical vitality, and courage. It is believed to ground energy, boost the immune system, and invigorate the wearer. Together, they provide a balanced spectrum of energy: the serenity to navigate emotional waters and the strength to face physical challenges.
Care and Cleaning
Preserving the beauty of these gemstones requires an understanding of their physical properties. * Aquamarine: Due to its hardness (7.5-8) and lack of significant cleavage planes, Aquamarine is relatively easy to care for. It can be safely cleaned using warm water, a mild soap (such as dish soap), and a soft brush. Ultrasonic and steam cleaners are generally safe for untreated and unheated stones, though caution is advised for stones that have been fracture-filled. * Bloodstone: With a hardness of 6.5-7, Bloodstone is durable but slightly more susceptible to scratching than Aquamarine. It should be cleaned with warm, soapy water and a soft cloth. Avoid harsh chemicals and ultrasonic cleaners, which could potentially damage the stone or dislodge the iron oxide inclusions that give it its characteristic red spots. Store both stones separately from harder gems like diamonds or sapphires to prevent scratching.
