March is unique among the months, possessing two officially recognized birthstones: aquamarine and bloodstone. These gemstones, while strikingly different in appearance, both carry rich histories and symbolism, representing clarity, courage, and the renewal associated with the arrival of spring. This article will delve into the geological origins, historical significance, gemological properties, and metaphysical beliefs surrounding these captivating March birthstones.
History and Lore
The designation of March birthstones is rooted in both ancient traditions and more recent standardization efforts. The month of March itself derives its name from Mars, the Roman god of war, reflecting a time when Roman soldiers resumed campaigns after the winter months. This historical context links the month to themes of strength and vitality, qualities embodied by both aquamarine and bloodstone.
Bloodstone, also known as heliotrope, boasts the longer tradition as a March birthstone. Its use dates back to antiquity, where it was believed to possess potent healing properties, particularly related to blood disorders and circulation. Some believed the stone would even turn blood red in the setting sun. This association with vitality and fortitude led to its use as a talisman for warriors and those seeking physical resilience.
Aquamarine, while gaining prominence more recently, also has a long and storied past. Ancient mariners believed aquamarine would calm the waves and ensure a safe voyage, earning it the reputation as a stone of protection for those at sea. It was also considered a symbol of enduring love and happiness in marriage, making it a popular choice for engagement rings. The standardization of birthstones by the Jewelers of America in 1912 solidified aquamarine as the modern embodiment of March’s birthstone, though bloodstone continues to hold its place as the traditional choice.
Geological Formation and Sources
Both aquamarine and bloodstone originate from distinct geological processes and are found in various locations around the globe. Aquamarine is a variety of the mineral beryl, a beryllium aluminum cyclosilicate. It forms in pegmatites, which are coarse-grained igneous rocks, often associated with granite formations. The presence of trace elements, particularly iron, gives aquamarine its characteristic blue to greenish-blue hues.
Brazil is a primary source of aquamarine, but significant deposits are also found in Nigeria, Madagascar, Zambia, Pakistan, and Mozambique. Within the United States, aquamarine can be found in Riverside and San Diego counties in California, and Colorado, where it is designated as the state gemstone.
Bloodstone, conversely, is a form of chalcedony, a microcrystalline variety of quartz. Its distinctive appearance – a dark green matrix speckled with red spots – is due to the presence of iron oxide inclusions. These inclusions give the stone its name, evoking the image of drops of blood. Bloodstone is typically found embedded in rocks or as pebbles in riverbeds. Major sources of bloodstone include India, Brazil, and Australia. Two distinct types of bloodstone are recognized: heliotrope and plasma, both sharing the characteristic red-spotted green appearance.
Gemological Properties
Aquamarine and bloodstone exhibit markedly different gemological properties, contributing to their unique aesthetic qualities.
Aquamarine:
- Chemical Formula: Be₃Al₂Si₆O₁₈
- Color: Pale blue to greenish-blue
- Transparency: Typically transparent
- Hardness (Mohs Scale): 7.5 – 8
- Crystal System: Hexagonal
Aquamarine’s clarity and lack of inclusions are highly valued, with faceted aquamarines often resembling clear water. Its hardness makes it durable enough for use in a variety of jewelry settings. The name “aquamarine” itself is derived from the Latin words “aqua” (water) and “mare” (sea), aptly describing its oceanic color palette.
Bloodstone:
- Chemical Formula: SiO₂ (Chalcedony) with iron oxide inclusions
- Color: Dark green with red spots
- Transparency: Typically opaque
- Hardness (Mohs Scale): 6.5 – 7
- Crystal System: Trigonal
Bloodstone’s opaque nature and distinctive red inclusions set it apart from aquamarine. While not as hard as aquamarine, its durability is sufficient for crafting cabochons and other ornamental objects. The red spots, caused by iron oxide, are the defining characteristic of bloodstone and contribute to its symbolic association with vitality and courage.
| Property | Aquamarine | Bloodstone |
|---|---|---|
| Chemical Formula | Be₃Al₂Si₆O₁₈ | SiO₂ |
| Color | Blue to Green-Blue | Dark Green w/ Red |
| Transparency | Transparent | Opaque |
| Hardness | 7.5 - 8 | 6.5 - 7 |
Symbolism and Metaphysical Beliefs
Both aquamarine and bloodstone are imbued with symbolic meaning and are believed to possess metaphysical properties. Aquamarine is strongly linked to the throat chakra, the center of communication and self-expression. It is believed to facilitate clear communication, promote spiritual growth, and encourage tranquility. Historically, it was considered a talisman for protection, shielding travelers from harm.
Bloodstone, on the other hand, is associated with the root chakra, which governs grounding, resilience, and vitality. It is believed to fortify the will, revitalize the mind and body, and promote courage. Its name and appearance evoke images of strength and perseverance, making it a symbol of fortitude. Bloodstone is also linked to purification and is thought to support the lymphatic system and circulation, promoting physical health.
Together, aquamarine and bloodstone offer a harmonious blend of peace and resilience, serving as spiritual guardians for those seeking balance and transformation. Aquamarine encourages clarity and emotional healing, while bloodstone provides strength and grounding.
Care and Cleaning
Due to their differing properties, aquamarine and bloodstone require slightly different care. Aquamarine, with its higher hardness, is relatively durable and can withstand regular wear. It can be cleaned with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, as these may damage the stone.
Bloodstone, being somewhat softer and more porous, requires gentler handling. It should be cleaned with a soft cloth and mild soapy water. Avoid prolonged exposure to harsh chemicals or abrasive materials, as these can dull its surface and potentially damage the iron oxide inclusions.
Conclusion
Aquamarine and bloodstone, the dual birthstones of March, represent a compelling pairing of contrasting yet complementary energies. Aquamarine embodies clarity, tranquility, and protection, while bloodstone symbolizes courage, vitality, and resilience. Their distinct geological origins, gemological properties, and rich histories contribute to their enduring appeal. Whether chosen for their aesthetic beauty, symbolic meaning, or metaphysical properties, these gemstones offer a unique and meaningful connection to the month of March and the promise of spring.
