The month of March is uniquely represented by two distinct and historically rich gemstones: Aquamarine and Bloodstone. While they differ dramatically in appearance, both have been cherished for millennia for their symbolic meanings and perceived protective qualities. Aquamarine, the primary modern birthstone, is celebrated for its tranquil, sea-blue hues, while its traditional counterpart, Bloodstone, is revered for its deep green canvas splashed with red iron oxide. Together, they offer a compelling narrative of geological wonder, ancient lore, and enduring appeal, making them a fascinating subject for gemstone enthusiasts and jewelry collectors alike.
The selection of these two stones for March is a result of the evolution of birthstone lists over centuries. The modern list, widely accepted today, designates Aquamarine as the primary stone, a choice that reflects its popularity and clarity. However, the traditional list, which traces its origins back to the Breastplate of Aaron described in the Old Testament and later formalized by historians like Josephus in the 1st century AD, included Bloodstone (then known as Jacinth) for March. This dual representation allows individuals born in March to choose between a gem that evokes the clear sky and another that speaks to the earth's strength.
History and Lore
The historical significance of Aquamarine is deeply intertwined with the sea, a connection made evident by its very name. Derived from the Latin words aqua (water) and marina (sea), the gemstone has been a talisman for sailors and travelers for centuries. Ancient mariners believed that Aquamarine, carved into the form of Neptune, the Roman god of the sea, possessed the power to calm waves and protect them from peril on their voyages. This lore extended beyond mere protection from storms; it was also thought to ensure a safe passage and bring good fortune to those who braved the oceans. The stone’s association with purity and tranquility made it a symbol of a clear conscience and a calm spirit.
In addition to its maritime connections, Aquamarine was believed to possess a range of other virtues. Historical texts suggest that the stone, as a member of the beryl family, was thought to grant the wearer protection against foes in both battle and litigation. It was also credited with making the wearer unconquerable, amiable, and quick of intellect. This multifaceted protective quality contributed to its esteem in ancient societies. The gemstone’s significance is not confined to antiquity; it continues to be a celebrated gem in modern times. In 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a magnificent dark blue rectangular step-cut aquamarine weighing 1,298 carats, a testament to the stone’s enduring prestige.
Bloodstone, also known as heliotrope, carries a more terrestrial and martial history. This cryptocrystalline quartz variety, characterized by its dark green chalcedony base with inclusions of red iron oxide, was known as the "martyr's stone." Its lore is rich with tales of courage and strength. Ancient warriors wore Bloodstone into battle, believing it would staunch bleeding and grant them victory. The red spots, resembling drops of blood, were seen as a powerful symbol of life force and vitality. In some traditions, Bloodstone was associated with the Christian narrative of the crucifixion, where the blood of Christ supposedly fell upon a green jasper stone at the foot of the cross, turning it red and imbuing it with sacred power. This connection made it a potent symbol of sacrifice and resurrection.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, placing it in the same mineral family as emeralds, morganite, and heliodor. Its characteristic blue-to-blue-green color is caused by trace amounts of iron within its chemical composition (Be₃Al₂Si₆O₁₈). The formation of large, well-formed aquamarine crystals requires specific geological conditions, typically found in pegmatites—coarse-grained igneous rocks—or in hydrothermal veins. These environments allow for the slow, stable growth of beryl crystals, often resulting in the exceptional clarity for which aquamarine is known.
The primary sources of high-quality Aquamarine are concentrated in South America and Africa. Brazil is the world’s leading producer, with significant deposits in the states of Minas Gerais, Bahia, and Espírito Santo. Brazilian aquamarines are renowned for their deep blue hues and large crystal sizes. Other notable sources include Madagascar, which produces a wide range of colors and qualities, as well as Nigeria, Mozambique, and Pakistan. These locations yield gemstones that supply the global market, from small, faceted stones for commercial jewelry to magnificent museum-quality specimens.
Bloodstone, or heliotrope, is a variety of cryptocrystalline quartz, composed of microcrystals of silicon dioxide (SiO₂). Its formation occurs at much lower temperatures than that of aquamarine and is often found in volcanic or sedimentary rock formations. The distinctive red inclusions are spots of iron oxide (hematite) that were incorporated into the silica gel during the stone's formation. The distribution and intensity of these red spots are key factors in the stone's aesthetic appeal and value.
Unlike many gemstones that are mined from deep underground, Bloodstone is often found in alluvial deposits—areas where water has eroded the host rock and concentrated the more durable stones. Major sources for Bloodstone include India, which is the most significant producer of gem-quality material. Other deposits are found in Australia, Brazil, China, and the United States. The stone’s relative abundance and widespread distribution make it an accessible and affordable gemstone for a variety of jewelry applications.
Gemological Properties
The two March birthstones possess vastly different gemological characteristics, which influence their use in jewelry and their care requirements. Aquamarine is a hard and durable gemstone, making it an excellent choice for rings, earrings, and pendants that will be worn daily.
Gemological Properties of Aquamarine and Bloodstone
| Property | Aquamarine | Bloodstone (Heliotrope) |
|---|---|---|
| Mineral Family | Beryl | Quartz (Cryptocrystalline) |
| Chemical Formula | Be₃Al₂Si₆O₁₈ | SiO₂ (with iron oxide inclusions) |
| Color | Blue to blue-green | Dark green with red spots |
| Hardness (Mohs) | 7.5 - 8 | 6.5 - 7 |
| Crystal System | Hexagonal | Trigonal (microcrystalline) |
| Refractive Index | 1.577 - 1.583 | 1.530 - 1.540 |
| Luster | Vitreous | Waxy to vitreous (when polished) |
Aquamarine’s hardness of 7.5 to 8 on the Mohs scale makes it resistant to scratching and suitable for most jewelry settings. Its vitreous luster and excellent clarity, often described as being "as clear as water," allow light to pass through it beautifully, enhancing its serene color. While faceted cuts are most common to maximize its brilliance, it can also be found in cabochon form, especially for star or cat's-eye varieties.
Bloodstone, with a hardness of 6.5 to 7, is slightly less durable than aquamarine but is still robust enough for many types of jewelry. However, it is more susceptible to scratching from harder materials and should be stored carefully. Its opaque nature means it is almost always cut into cabochons, beads, or cameos to best display its unique color combination. The waxy to vitreous luster of a polished bloodstone gives it a subtle, earthy appeal. The value of bloodstone is primarily determined by the intensity of its green color and the distribution and brightness of its red spots.
Symbolism and Metaphysical Beliefs
Beyond their physical beauty, both March birthstones are steeped in symbolism and are widely used in metaphysical practices. Aquamarine is synonymous with serenity, clarity, and emotional balance. It is often referred to as the "stone of courage." Its calming energies are believed to soothe fears, reduce stress, and quiet the mind, making it a popular choice for meditation and spiritual work. In the realm of crystal healing, Aquamarine is associated with the throat chakra, thought to enhance clear communication and self-expression. It is also considered a stone of love and commitment, often given as a gift to symbolize loyalty and a happy marriage.
Bloodstone, in contrast, is a stone of vitality, strength, and physical energy. Its symbolism is rooted in life force and courage. It is believed to be a powerful grounding stone that connects the wearer to the earth's stabilizing energies. Metaphysical practitioners use Bloodstone to cleanse the blood, boost the immune system, and increase endurance. It is known as a "warrior's stone," providing courage in difficult situations and helping to overcome obstacles. Its energy is dynamic and motivating, making it an excellent stone for those needing a boost of confidence and perseverance.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone jewelry. The differing properties of Aquamarine and Bloodstone require slightly different approaches.
Aquamarine is relatively easy to care for due to its hardness and good toughness. It can be safely cleaned using warm, soapy water and a soft brush. It is important to rinse the jewelry thoroughly to remove any soap residue that could dull its luster. For stubborn dirt, a soft brush can be used to gently remove debris. Ultrasonic and steam cleaners are generally safe for aquamarine, provided the stone has no fractures or inclusions. However, it is always prudent to exercise caution and consult a professional if the stone's integrity is in question. When storing aquamarine jewelry, it should be kept in a soft pouch or a jewelry box with compartments to prevent it from scratching softer stones or being scratched by harder ones. It is also advisable to keep it away from prolonged direct sunlight, as some aquamarines may experience slight fading over time.
Bloodstone requires a bit more care due to its lower hardness and potential for porosity. The safest cleaning method is using warm, soapy water and a soft cloth or brush. It is crucial to avoid harsh chemicals, acids, and strong detergents, as these can damage the stone's surface. Ultrasonic cleaners should be avoided, as the vibrations could potentially dislodge the iron oxide inclusions or cause fractures. Similarly, steam cleaning is not recommended due to the heat and potential for thermal shock. Bloodstone should be stored separately from harder gemstones like diamonds, sapphires, and even aquamarine to prevent scratching. A soft pouch is ideal for its protection.
