The arrival of March heralds the transition from the starkness of winter to the tentative promise of spring, a period of renewal and awakening. For those born in this month, this transition is mirrored in their birthstones: the serene, oceanic aquamarine and the rugged, earthy bloodstone. These two gems, vastly different in appearance and character, share a unified purpose rooted in protection and well-being. Aquamarine, with its tranquil blue-green hues, evokes the vastness of the sea, while bloodstone, a dark green chalcedony splashed with red iron oxide, speaks to the vitality of the earth. Together, they offer a comprehensive palette of meaning for the March-born, representing both calm resilience and robust strength.
As official birthstones recognized by modern standards, both aquamarine and bloodstone have rich histories that span ancient civilizations, from the treasuries of Roman emperors to the talismans of medieval warriors. This article will explore the dual heritage of March's birthstones, delving into their geological origins, gemological properties, historical lore, and the enduring symbolism that continues to captivate gemstone enthusiasts and jewelry buyers today. We will examine the distinct characteristics that define each stone, providing a detailed guide to their significance, care, and the fascinating legends that have secured their place as cherished gems for millennia.
History and Lore
The historical narratives surrounding March's birthstones are as distinct as the gems themselves, yet they converge on themes of protection, health, and safe passage. Aquamarine's lore is intrinsically tied to the sea, a legacy reflected in its very name, which derives from the Latin words aqua (water) and marina (sea). This connection forged a powerful bond with ancient mariners, who believed the gem was a sacred treasure of mermaids and a potent talisman for ensuring safe voyages. They claimed that aquamarine could calm waves and protect sailors from the perils of the ocean. Beyond its nautical associations, the stone was also thought to bring happiness in marriage and was widely revered across ancient cultures. The Romans, Greeks, and Egyptians all valued aquamarine not only for its aesthetic beauty but also for its perceived protective qualities. In the context of battle, beryl—the mineral group to which aquamarine belongs—was believed to offer the wearer protection against foes in both combat and litigation, fostering a sense of being unconquerable and amiable while also quickening the intellect.
Bloodstone, in contrast, carries a lore steeped in the drama of terrestrial life and sacrifice. Its very name, and the vivid red spots that characterize it, are linked to Christian legend. According to one prominent tradition, the stone was formed at the foot of the cross, where the blood of Christ dripped onto the dark green jasper, imbuing it with sacred power. This association with martyrdom and lifeblood made it a symbol of immense courage and sacrifice. Another legend recounts how the stone was used to staunch the wounds of martyrs, cementing its reputation as a bringer of health and strength. During the Middle Ages, bloodstone was not merely a passive talisman; it was actively used by practitioners for alchemical and medicinal purposes, believed to stop bleeding and cure ailments. Its reputation for granting strength and perseverance extended into the Renaissance, where it was thought to bestow the power to control weather and defeat enemies, making it a favored stone for those in positions of power and conflict.
Geological Formation and Sources
Understanding the origins of these gemstones requires a look into their distinct geological backgrounds, which account for their vastly different appearances. Aquamarine is a variety of the mineral beryl, placing it in the same family as the emerald (green beryl) and morganite (pink beryl). It forms within igneous rocks, specifically in pegmatites—coarse-grained intrusive igneous rocks—which are often found in mountain ranges. These pegmatites provide the ideal environment for large, well-formed crystals of beryl to grow. The trace element responsible for aquamarine’s signature blue to greenish-blue color is ferrous iron.
The primary sources for high-quality aquamarine are geologically diverse. Brazil is a leading producer, known for yielding large, transparent crystals that are highly prized in the gem market. Other significant sources include Pakistan, particularly the Skardu region, which produces gems with a deep, saturated blue color often favored by connoisseurs. Madagascar is another key source, known for a wide range of colors and sizes. In the United States, pegmatites in states like North Carolina and Maine have historically produced aquamarine, though often in smaller quantities. The formation process can result in exceptionally large crystals; in fact, aquamarine is known for producing some of the largest gem-quality crystals of any beryl variety, with faceted stones weighing thousands of carats not being uncommon.
Bloodstone, on the other hand, is a cryptocrystalline variety of quartz, specifically a form of jasper. It is composed of silicon dioxide and its characteristic dark green color comes from the mineral chlorite or actinolite included within the quartz matrix. The distinctive red spots, which give the stone its name and lore, are inclusions of iron oxide, typically hematite. Unlike the large, crystalline formation of aquamarine, bloodstone forms in nodules or veins within sedimentary or metamorphic rocks. It is often found in association with other forms of chalcedony and jasper. Historically, one of the most significant sources for bloodstone was India, which supplied the gem to the ancient world. Today, other notable sources include Australia, Brazil, China, and parts of Europe. The material from these locations varies in the intensity of its green color and the prominence and distribution of its red inclusions.
Gemological Properties
The fundamental differences between aquamarine and bloodstone are most clearly defined by their gemological properties. Aquamarine is a crystalline beryl, while bloodstone is a microcrystalline quartz. This distinction is crucial to understanding their durability, appearance, and value.
Aquamarine is prized for its clarity and color. It belongs to the trigonal crystal system and has a Mohs hardness of 7.5 to 8, making it a durable choice for all types of jewelry, including rings that are subject to daily wear. Its refractive index ranges from 1.577 to 1.583, and it is doubly refractive. A key characteristic of high-quality aquamarine is its exceptional clarity; faceted aquamarines are often free from inclusions, appearing as clear as water, which symbolizes purity of spirit and soul. The most valuable color is a deep, pure blue or a slightly greenish blue. While aquamarine crystals can be found in very large sizes, the color often becomes more saturated in larger stones. The famous aquamarine given to First Lady Eleanor Roosevelt in 1936 by the government of Brazil, for instance, was a dark blue rectangular step-cut stone weighing 1,298 carats, demonstrating the gem's capacity for both size and color intensity.
Bloodstone presents a completely different set of properties. As a variety of chalcedony (a microcrystalline form of quartz), it has a hardness of 6.5 to 7 on the Mohs scale, making it slightly less hard than aquamarine but still suitable for jewelry, particularly in protective settings like cabochons. It is typically cut as a cabochon to best display its characteristic red "blood" spots against the dark green background. Its refractive index is lower than that of aquamarine, ranging from 1.535 to 1.539. Bloodstone is generally opaque, and its value is determined by the intensity of its green color and the distinctness, distribution, and contrast of its red iron oxide inclusions.

Symbolism and Metaphysical Beliefs
The symbolism of March's birthstones is deeply intertwined with their historical lore and physical appearance. Aquamarine is overwhelmingly associated with the element of water, and its metaphysical beliefs center on emotional balance, clarity, and protection. It is known as the "Stone of Courage," believed to calm fears and soothe anxiety, providing the emotional strength needed to confront challenges. Its serene energy is said to promote clear, reasoned communication, especially during confrontational situations, and to quiet the mind for enhanced meditation.
For travelers, aquamarine remains a powerful talisman. It is said to protect those who journey by sea, guarding them from drowning and other dangers. This belief has extended to all forms of long-haul travel, including driving and flying, and is even thought to alleviate the fear of water. In relationships, it is believed to foster happiness and commitment. The stone’s connection to the throat chakra makes it a powerful tool for those seeking to express their truth with compassion and clarity.
Bloodstone, with its earthy energy and "blood" of life, symbolizes strength, vitality, and perseverance. It is a grounding stone that connects the wearer to the life force of the Earth, promoting courage and the ability to overcome adversity. Historically, it was known as a "martyr's stone," and its energy is one of self-sacrifice and noble purpose. Metaphysically, bloodstone is considered a powerful healer. It is believed to purify the body, boost the immune system, and bring health and vitality. The red flecks are seen as drops of life-giving energy, making it a stone for revitalizing one's physical and spiritual well-being. It is often used to ground high-frequency energy into the physical body and to provide a protective shield against negativity and psychic attack.
Care and Cleaning
Due to their differing hardness and structural properties, aquamarine and bloodstone require slightly different approaches to care, though both are durable enough for regular wear in jewelry.
Aquamarine, with its hardness of 7.5 to 8 and good toughness, is relatively easy to care for. It is resistant to scratching and chipping, making it a suitable choice for rings, earrings, and pendants worn daily. To clean aquamarine, use warm, soapy water and a soft brush. Be sure to rinse the gemstone thoroughly to remove any soap residue, which can create a film on its surface. While aquamarine is generally stable, it is advisable to avoid sudden and extreme temperature changes, as this can cause fractures in the stone. Ultrasonic and steam cleaners are generally safe for aquamarine, provided the stone has no significant fractures or inclusions. However, if the stone has been fracture-filled (an uncommon treatment for aquamarine), these cleaning methods should be avoided.
Bloodstone, as a member of the quartz family with a hardness of 6.5 to 7, is also quite durable but slightly more susceptible to scratching than aquamarine. It can be cleaned using the same method: warm, soapy water and a soft brush. Because bloodstone is often cut as a cabochon, it is important to pay attention to the polish on the dome to maintain its luster. Bloodstone is generally stable with regard to light and can be exposed to moderate heat without damage. However, like all gemstones, it should be protected from sharp blows and hard surfaces to prevent chipping. Ultrasonic cleaners are typically safe for untreated bloodstone, but it is always prudent to avoid them for stones whose treatment or origin is unknown.
Conclusion
Aquamarine and bloodstone, the two birthstones of March, offer a compelling study in contrasts. One embodies the tranquil, fluid power of the sea, while the other represents the enduring, vital strength of the earth. Aquamarine, the crystalline blue beryl, has been cherished for millennia as a protector of travelers and a symbol of purity, clarity, and calm. Its physical properties—high hardness, exceptional clarity, and serene color—make it a premier gemstone in the world of fine jewelry. Bloodstone, the opaque green jasper splashed with red, carries a more terrestrial and dramatic history as a stone of courage, healing, and sacrifice.
