By understanding the unique attributes of both Aquamarine and Bloodstone, one can fully appreciate why they remain enduring favorites among gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
The tradition of associating specific gemstones with birth months is a practice with deep historical roots. The concept is often traced back to the 1st century AD, when historians attempted to connect the twelve stones described in the Breastplate of Aaron, as detailed in the Book of Exodus, to the twelve months of the year and the corresponding zodiac signs. In these early lists, Bloodstone was the sole birthstone assigned to March. Its reputation as a protective and powerful talisman was well-established in the ancient world.
Bloodstone, also known historically as heliotrope, was revered for its perceived ability to imbue its wearer with courage and strength. The stone's appearance—a dark green chalcedony speckled with red iron oxide inclusions, resembling drops of blood—fueled its lore. Ancient warriors would often carry it into battle, believing it could staunch wounds and protect them from harm. Its connection to the Roman god Mars, for whom the month of March is named, further solidified its image as a stone of war and vitality. The name "March" itself derives from "Martius," the Roman calendar's first month, which marked the resumption of military campaigns after the winter lull.
The journey to the modern birthstone list was not a direct one. For centuries, the identification of gems mentioned in ancient texts was fraught with ambiguity due to the lack of scientific gemological classification. It was not until much later that standardized lists began to emerge. A significant milestone occurred in 1912 when the American National Association of Jewelers (now Jewelers of America) convened to create an official, standardized birthstone chart. This list was designed to be commercially viable and consistent for jewelers. In this modernization process, Aquamarine was added as the primary birthstone for March, likely due to its growing popularity and availability in the gem market. This addition provided a lighter, more ethereal alternative to the earthy Bloodstone, which remained on the list as a traditional or alternative stone.
While the modern list solidified Aquamarine's position, it did not erase the historical significance of Bloodstone. Today, both are officially recognized as March birthstones, allowing those born in the month to choose between a gem that reflects the sky and sea, or one that embodies the enduring strength of the earth. This duality offers a broad spectrum of meaning, from peace and tranquility to courage and resilience.
Aquamarine: The Gem of the Sea
Aquamarine, with its name derived from the Latin words aqua (water) and marina (sea), is a gemstone that perfectly captures the serene beauty of the ocean. Its color range, from the palest icy blue to the deep, tranquil blue-green of tropical waters, has made it a favorite for jewelry that evokes a sense of calm and clarity.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, placing it in the same family as emerald, morganite, and heliodor. Its characteristic blue-to-green color is caused by trace amounts of iron within its crystal structure. Beryl forms in pegmatites—coarse-grained igneous rocks—where mineral-rich fluids cool slowly, allowing for the growth of large, well-formed crystals. The most significant deposits of high-quality Aquamarine are found in Brazil, particularly in the states of Minas Gerais, Bahia, and Espírito Santo. Brazil is renowned for producing large, transparent crystals with the highly prized deep blue color.
Other notable sources include Pakistan's Skardu region, which yields crystals with a vivid, saturated blue hue, and Madagascar, known for its unique "Santa Maria" colored Aquamarine. While these locations produce some of the finest material, smaller deposits can also be found in Nigeria, Mozambique, and several states in the United States, such as Colorado. The size of Aquamarine crystals can be remarkable; gemologists have faceted stones weighing thousands of carats from single crystals, a testament to the stability and longevity of its growth environment.
Gemological Properties
As a member of the beryl family, Aquamarine possesses a set of distinct physical and chemical characteristics that define it.
- Chemical Formula: Be₃Al₂(SiO₃)₆ (Beryllium Aluminum Cyclosilicate) with traces of Iron (Fe)
- Crystal System: Hexagonal
- Hardness: 7.5 to 8 on the Mohs scale, making it durable enough for all types of jewelry, including rings and daily-wear pieces.
- Refractive Index: 1.567 to 1.590
- Specific Gravity: 2.68 to 2.80
- Clarity: Aquamarine is typically "eye-clean," meaning it lacks visible inclusions to the naked eye. This clarity is one of its most appealing attributes, allowing light to pass through unimpeded and enhancing its signature brilliance. Inclusions, when present, can appear as long, liquid-filled needles or tiny mineral crystals known as "jardin."
One of the most important considerations for gemologists and buyers is color. While the primary birthstone color for March is described as light blue, the most valuable Aquamarines exhibit a medium to medium-dark, strongly saturated blue to greenish-blue hue. The palest shades, which are almost transparent, are far more common and thus less valuable. Heat treatment is a standard and accepted industry practice used to enhance the color of most Aquamarine. The natural greenish-brown or yellowish hues of many raw crystals are transformed into a more desirable, stable blue through controlled heating.
Symbolism and Metaphysical Beliefs
The lore surrounding Aquamarine is intrinsically tied to its maritime connection. For centuries, sailors believed the gem was a treasure of mermaids and a powerful protector against the perils of the ocean. It was thought to ensure a safe voyage and guard against drowning and storms. This protective quality was not limited to the sea; travelers also carried Aquamarine for protection on land.
Beyond its role as a talisman for travelers, Aquamarine is widely associated with peace, tranquility, and emotional balance. It is believed to calm the mind, soothe anxieties, and promote clear communication. In modern crystal healing practices, it is often referred to as the "Stone of Courage," said to provide the strength needed to overcome fear and conflict. Its connection to the throat chakra makes it a popular stone for those seeking to express themselves more truthfully and eloquently. Furthermore, Aquamarine has a long-standing association with marital happiness and is often given as a gift to celebrate anniversaries.
Bloodstone: The Stone of Martyrs and Warriors
In stark contrast to the serene Aquamarine, Bloodstone (also known as heliotrope) is a gemstone of intense energy and dramatic appearance. A variety of cryptocrystalline quartz, its dark green jasper base is vividly splashed with inclusions of red iron oxide, creating a visual effect that has captivated humanity for millennia.
Geological Formation and Sources
Bloodstone is a member of the chalcedony family, which is itself a microcrystalline form of quartz (silicon dioxide). It forms in volcanic or metamorphic rocks, often in nodules or veins. The distinct coloration is a result of its formation process: the green comes from chlorite or actinolite inclusions, while the red "drops" are caused by iron oxide (specifically, hematite) that was present during or after the stone's initial formation.
While Bloodstone can be found in various parts of the world, some of the most historically significant and commercially important sources are located in India. Indian Bloodstone is often prized for its deep, uniform green color and sharply contrasting red spots. Other notable sources include Australia, Brazil, China, and the United States (specifically Oregon). The quality of Bloodstone is judged by the intensity of its green base and the prominence and distribution of the red inclusions.
Gemological Properties
As a form of chalcedony, Bloodstone shares the properties common to this mineral group, but its specific characteristics give it a unique identity.
- Chemical Formula: SiO₂ (Silicon Dioxide)
- Crystal System: Trigonal (microcrystalline)
- Hardness: 6.5 to 7 on the Mohs scale. This makes it suitable for jewelry, though it is slightly less hard than Aquamarine and can be more susceptible to scratching if worn daily in a ring.
- Refractive Index: 1.535 to 1.539
- Specific Gravity: 2.58 to 2.64
- Transparency: Opaque. Unlike Aquamarine, Bloodstone does not allow light to pass through. It is almost always cut and polished into a smooth, rounded cabochon shape to best display its dramatic color pattern.
Bloodstone's opaque nature means that clarity is not a grading factor as it is with transparent gems. Instead, value is determined by the intensity of the green color and the visual appeal of the red spots. Stones with a rich, deep forest green and bright, well-distributed red inclusions are considered the finest.
Symbolism and Metaphysical Beliefs
The symbolism of Bloodstone is as powerful as its appearance. Its ancient reputation as a protective stone for warriors is legendary. It was believed to have the power to heal wounds, stop bleeding, and bestow victory in battle. The stone's association with martyrdom in Christian lore—said to have been formed at the crucifixion of Christ, with drops of his blood falling onto the green stone at the foot of the cross—added a layer of sacred significance. This story cemented its use as a protective talisman for the Christian faithful.
In addition to its protective qualities, Bloodstone is known as a powerful energizer. It is believed to boost vitality, increase endurance, and revitalize the body and mind. It is a stone of courage, said to help one overcome fear, anxiety, and confusion. For those seeking to take decisive action in their lives, Bloodstone is thought to provide the necessary strength and confidence.
Alternative and Guardian Birthstones
While Aquamarine and Bloodstone are the two primary traditional birthstones for March, some historical and esoteric birthstone lists offer other gems for specific birth dates within the month. These lists, which often differ from the modern commercial charts, provide a more nuanced approach to gemstone associations.
For example, some traditions designate a "guardian angel" birthstone for each day of the year. For individuals born between March 1 and March 31, the guardian angel birthstone is Ruby. The "king of precious gemstones," as it was known in Sanskrit, was believed to reconcile disagreements, bring health, and ensure safety and luck for the wearer.
Another alternative system assigns "apostle" birthstones to the month. For all birthdays from March 1 to March 31, the apostle birthstone is Emerald. Revered as a sacred gemstone associated with intelligence, wealth, and action, Emerald was also valued as an alternative to diamonds in engagement rings due to its symbolism of fidelity and happiness.
It is important to note that these alternative stones—Ruby and Emerald—are not listed on the standard birthstone charts maintained by major trade organizations. However, they represent a deeper, more historical layer of gemstone lore that appeals to those interested in the spiritual and symbolic dimensions of birthstones.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone jewelry. The distinct physical properties of Aquamarine and Bloodstone dictate different cleaning and handling methods.
Caring for Aquamarine
Thanks to its hardness of 7.5 to 8 on the Mohs scale, Aquamarine is a relatively durable gemstone. It is resistant to scratching and can be safely worn in rings, bracelets, and other jewelry that may encounter daily wear. However, like all gemstones, it can still be damaged by sharp blows.
- Cleaning: The safest way to clean Aquamarine is with warm, soapy water and a soft brush. Be sure to rinse it thoroughly to remove any soap residue. Ultrasonic cleaners are generally safe for untreated and heat-treated Aquamarine, but should be avoided if the stone has significant fractures or liquid inclusions. Steam cleaning is also acceptable, provided the stone is free of major inclusions. Avoid harsh chemicals, such as bleach or chlorine, which could damage the stone or the metal setting.
- Storage: Store Aquamarine jewelry separately from other gems and metals to prevent scratches. A soft cloth pouch or a compartmentalized jewelry box is ideal.
Caring for Bloodstone
Bloodstone, with a hardness of 6.5 to 7, is slightly softer and more brittle than Aquamarine. Its opaque nature and potential for fractures require a more cautious approach to care.
- Cleaning: Like Aquamarine, Bloodstone should be cleaned using warm, soapy water and a soft brush. It is crucial to avoid harsh chemicals and acids, as these can dull its polished surface or damage the stone. It is also advisable to avoid ultrasonic and steam cleaners, as the vibrations and heat can potentially worsen any existing fractures.
- Storage: Due to its relative softness, Bloodstone should be stored carefully to prevent being scratched by harder materials. It is best kept in its own soft cloth pouch.
Conclusion
The birthstones of March, Aquamarine and Bloodstone, offer a fascinating duality that perfectly reflects the month's transitional nature. Aquamarine, the "water of the sea," embodies tranquility, clarity, and ethereal beauty with its light blue to greenish-blue hues. Its durability and eye-clean clarity make it a prized gem for fine jewelry, while its rich lore as a protector of sailors and a symbol of marital bliss adds to its allure.
In contrast, Bloodstone, the "stone of the martyr," presents an earthy and powerful persona. Its deep green body dotted with crimson splashes speaks of courage, vitality, and protection. As the original March birthstone, its historical significance is profound, connecting the wearer to ancient traditions of warriors and faithful followers.
Together, these two official March birthstones provide a meaningful choice for those born in the month.
