The month of March is uniquely represented in the gemological world by two distinct and historically rich birthstones: Aquamarine and Bloodstone. While visually disparate—one evoking the tranquil hues of the ocean and the other the rugged earth—both stones share a profound legacy of symbolism centered on protection, health, and courage. Modern birthstone charts typically designate Aquamarine as the primary gem for March, yet Bloodstone retains its status as a revered traditional alternative, offering a fascinating duality for those born in this transitional month. This comprehensive guide explores the geological origins, gemological properties, historical lore, and modern significance of these two remarkable stones.
The Modern Standard: Aquamarine
Aquamarine, the most celebrated March birthstone, is a variety of the mineral beryl, placing it in the esteemed company of emeralds and morganite. Its name is derived directly from the Latin words aqua (water) and marina (sea), a fitting descriptor for its signature color palette that ranges from the palest, almost colorless sky-blue to deep, saturated greenish-blues reminiscent of tropical waters. The gem’s allure lies in its exceptional clarity and vitreous luster, which allows light to pass through with a purity that symbolizes a clear spirit and soul.
Geological Formation and Sources
As a member of the beryl family, Aquamarine forms from beryllium aluminum cyclosilicate. Its characteristic blue-to-green hues are the result of trace amounts of ferrous iron within its crystal structure. Large, gem-quality crystals are found in pegmatite deposits, which are igneous rocks formed from the slow cooling of magma.
The primary sources for high-quality Aquamarine are concentrated in South America and Africa. According to the provided materials, Brazil stands as the largest supplier, consistently yielding stones of impressive size and clarity. Other significant mining locations include Pakistan, Nigeria, and Madagascar, each contributing unique variations in color and saturation to the global market. The widespread availability of Aquamarine has made it a relatively accessible gemstone, though the finest deep-blue specimens without visible inclusions command premium prices.
Historical Lore and Symbolism
Aquamarine’s history is deeply intertwined with the sea, a connection that has been reinforced for centuries. Ancient mariners believed the gem was a talisman of good luck and protection, asserting that it could calm turbulent waves and safeguard them from the perils of the ocean. This belief was so pervasive that the stone was often carried by sailors as a protective charm.
Beyond its nautical significance, Aquamarine was also attributed with powers that could enhance marital happiness and bring about reconciliation. In the realm of medieval folklore, beryl (the mineral family) was thought to grant the wearer protection against foes in battle and litigation. It was believed to make a person unconquerable, amiable, and intellectually sharper. The GIA notes that these historical beliefs underscore the stone's long-standing association with clarity, calmness, and inner peace. The gem’s significance is further cemented by its role as a gift for the 19th wedding anniversary.
Gemological Properties
Aquamarine is prized not only for its beauty but also for its durability, making it an excellent choice for all forms of jewelry, including engagement rings. Its physical and chemical characteristics are well-defined:
- Chemical Composition: Be₃Al₂Si₆O₁₈ (Beryllium Aluminum Cyclosilicate) with trace Iron (Fe).
- Hardness: 7.5 to 8 on the Mohs scale, making it resistant to scratching and suitable for daily wear.
- Crystal System: Hexagonal.
- Refractive Index: 1.577 to 1.583 (±0.004).
- Density: 2.68 to 2.80.
- Luster: Vitreous (glass-like).
The most prized Aquamarine possesses a clear, bright blue shade with excellent transparency and minimal inclusions. While large crystals are common, the value increases significantly with the depth of color and the absence of visible flaws.
The Traditional Alternative: Bloodstone
Bloodstone, also historically known as Heliotrope, offers a stark and dramatic contrast to Aquamarine. It is a variety of Chalcedony, which is a microcrystalline form of quartz (silicon dioxide). Bloodstone is characterized by its deep, earthy green body color, which is richly speckled with vivid red or orange inclusions of iron oxide or jasper. These red spots, which resemble drops of blood, are the source of the stone's powerful name and symbolism.
Geological Formation and Sources
Bloodstone forms in volcanic or metamorphic rock environments. As a cryptocrystalline quartz, its individual crystals are too small to be seen without magnification. It is found in various locations around the world, though the provided sources do not specify the primary mining countries for this gem. Its relative abundance as a form of quartz makes it an affordable and accessible stone for cabochon-cut jewelry.
Historical Lore and Symbolism
The lore surrounding Bloodstone is rich with themes of vitality, courage, and sacrifice. Its most famous legend connects it directly to the crucifixion of Christ. The story holds that the stone was formed when the blood of Christ fell upon the green earth at the foot of the cross, staining the stones with his blood. This Christian association made it a symbol of the Passion and a powerful amulet for martyrs and saints.
However, its protective powers predate Christian traditions. In ancient Babylon, the stone was used in rituals and magic. Roman gladiators wore Bloodstone as a talisman to protect them from injury and death in the arena. It was also believed to have the power to stop bleeding, heal wounds, and purify the air, making it a popular stone for health and well-being. Like Aquamarine, it was thought to grant the wearer strength and courage, but in a more visceral, battlefield context. The provided sources explicitly link Bloodstone to "courage on the battlefield" and "vitality," reinforcing its role as a stone of action and endurance.
Gemological Properties
Bloodstone’s properties are distinct from Aquamarine, primarily due to its different mineral family and typical cut.
- Chemical Composition: SiO₂ (Silicon Dioxide).
- Hardness: 6.5 to 7 on the Mohs scale.
- Crystal System: Trigonal.
- Luster: Waxy to vitreous.
- Transparency: Opaque.
Due to its opacity, Bloodstone is almost exclusively cut en cabochon (a smooth, rounded dome) to best display its rich color and the dramatic contrast of the red "blood" spots against the green background. It is frequently used in signet rings, bracelets, and ornamental carvings.

Care and Cleaning
The durability of a gemstone dictates the appropriate methods for its care and cleaning. Given their different hardness levels and chemical compositions, Aquamarine and Bloodstone require slightly different handling.
Aquamarine is a durable gem suitable for everyday wear. Its hardness of 7.5 to 8 makes it resistant to scratches from most everyday materials. It can be safely cleaned using warm water, a small amount of mild dish soap, and a soft brush (such as a toothbrush). Ultrasonic cleaners are generally safe for Aquamarine, provided the stone has no significant fractures or inclusions. However, steam cleaning is not recommended, as sudden temperature changes can potentially damage the stone.
Bloodstone, while reasonably durable, is softer than Aquamarine and can be scratched by harder materials. As a form of quartz, it is stable under normal conditions but should be protected from sharp blows and extreme temperature changes. The safest method for cleaning Bloodstone is with warm, soapy water and a soft cloth. It should be dried thoroughly after cleaning. Ultrasonic cleaners and steam cleaners should be avoided, as the vibrations and heat could potentially damage the stone or loosen any settings.
