For those born in the month of March, the choice of a birthstone is not a single gem but a fascinating duality that spans centuries of tradition, geography, and gemological evolution. The modern birthstone chart, standardized for much of the Western world, designates Aquamarine as the primary gem for March. However, this was not always the case. A rich historical tradition, particularly in British and older Western lore, associates March with Bloodstone. This article delves into the comprehensive history, geological origins, symbolic meanings, and gemological properties of both stones, providing a detailed guide for enthusiasts, collectors, and individuals seeking a deeper connection to their March birthstone.
The Evolution of Birthstone Lists: From Lore to Standardization
The concept of associating specific gemstones with birth months is not a modern invention but a practice steeped in ancient history. The most influential historical reference is the Breastplate of Aaron, a sacred garment described in the Old Testament, which featured twelve stones representing the twelve tribes of Israel. This biblical foundation, coupled with the writings of ancient historians like Pliny the Elder in the 1st century AD, who described the stones of the breastplate and their alleged therapeutic properties, established an early framework for gemstone symbolism.
Over the centuries, these associations evolved into various traditional birthstone charts. These lists, passed down through generations, often differed significantly based on region, culture, and available gemstones. For example, traditional British charts frequently included Bloodstone for March. Similarly, the Hindu Ayurvedic system based gemstone associations on astrological signs rather than calendar months, and Tibetan mystical charts featured stones with unique spiritual significance. These diverse traditions demonstrate a long-held belief in the power and symbolism of gemstones.
The modern American birthstone chart began to take shape in 1912 when the National Association of Jewelers (now Jewelers of America) created a standardized list. This was a pivotal moment, establishing a unified system for the United States jewelry industry and consumers. This initial list, however, was not static. It underwent several revisions, with the most significant update for March occurring in 1952 when Aquamarine was officially added to the list alongside Bloodstone. Later, in 2016, the American Gem Trade Association (AGTA) further expanded the options by adding Jade to the modern list for March. This evolution reflects a shift from purely historical or mystical associations toward a system that also considers market availability, consumer preference, and the gemological diversity of the market.
The table below, derived from the provided materials, summarizes the key differences between traditional and modern birthstone lists for March, illustrating this evolution.
| Month | Traditional Birthstone(s) | Modern Birthstone(s) |
|---|---|---|
| March | Bloodstone | Aquamarine, Bloodstone (UK) |
This comparison demonstrates that while some stones, like garnet, amethyst, diamond, emerald, ruby, and sapphire, have maintained their association with specific months across both lists, others, such as those for March, have been supplemented or replaced. The modern chart, while acknowledging these traditions, prioritizes standardization and marketability. The addition of alternative stones, particularly those more readily available and affordable, reflects a desire to cater to a broader consumer base.
Aquamarine: The Modern Birthstone of March
Aquamarine, the primary modern birthstone for March, is a variety of the mineral beryl, known for its captivating blue to blue-green hues that evoke the clarity and tranquility of seawater. Its name is derived from the Latin aqua marina, meaning "sea water," a fitting descriptor for its most prized color.
Geological Formation and Sources
Aquamarine forms in pegmatites—coarse-grained igneous rocks—under conditions of high temperature and pressure. The presence of trace amounts of iron in its crystal structure is responsible for its characteristic blue coloration. The intensity of the color can vary significantly, with deeper, more saturated blues generally commanding higher values. Major sources of high-quality aquamarine include Brazil, which is renowned for producing large, well-formed crystals. Other significant mining locations include Nigeria, Mozambique, Madagascar, and Pakistan. The geological conditions required for large, gem-quality aquamarine crystals are relatively specific, making deposits with these characteristics economically valuable.
Gemological Properties
As a member of the beryl family, aquamarine shares properties with other well-known gems like emerald (green beryl) and morganite (pink beryl). Its key gemological characteristics are as follows:
- Chemical Composition: Be₃Al₂Si₆O₁₈ (Beryllium Aluminum Silicate) with trace iron (Fe) causing the blue color.
- Crystal System: Hexagonal.
- Hardness: 7.5 to 8 on the Mohs scale, making it a durable gemstone suitable for all types of jewelry, including rings that are worn daily. It is harder than most other blue gemstones like tanzanite (6.5-7) and significantly harder than stones like turquoise (5-6).
- Refractive Index: 1.577 to 1.583.
- Specific Gravity: 2.68 to 2.70.
- Clarity: Aquamarine is typically "eye-clean," meaning it lacks visible inclusions to the naked eye. Unlike emeralds, which are famous for their inclusions (jardin), fine aquamarine is prized for its clarity and transparency. Some stones may contain needle-like inclusions or tiny liquid-filled tubes, but these are generally not detrimental to the stone's appearance unless they are numerous or poorly placed.
- Color: The most valued color is a deep, saturated blue with a slight greenish undertone. Lighter shades are more common and less valuable, but the stone's clarity and size can compensate. Heat treatment is commonly used to enhance the color of aquamarine, turning naturally pale greenish-blue stones into a more desirable, uniform blue. This treatment is stable and widely accepted in the gem trade.
Symbolism and Metaphysical Beliefs
Aquamarine has been associated with various symbolic meanings throughout history. Its name and color directly link it to the sea, making it a traditional talisman for sailors, believed to ensure safe voyages and protect against storms. The stone is also linked to courage, communication, and clarity. In modern crystal healing and metaphysical beliefs, aquamarine is often considered a stone of emotional balance, said to soothe fears, reduce stress, and promote clear, honest communication. It is associated with the throat chakra and is believed to aid in self-expression. For those born in March, it symbolizes wisdom, serenity, and the renewal of spirit, aligning with the transitional nature of the spring season.
Care and Cleaning
Given its good hardness and lack of cleavage (a tendency to break along flat planes), aquamarine is relatively easy to care for. It can be cleaned with warm, soapy water and a soft brush. Ultrasonic cleaners are generally safe for untreated aquamarine, but caution is advised for stones that have undergone fracture filling (a less common treatment). Steam cleaning is not recommended due to the potential for thermal shock, especially if the stone has inclusions. As with all gemstones, it is best to store aquamarine jewelry separately to avoid scratches from harder gems like diamonds or sapphires.
Bloodstone: The Traditional March Birthstone
Bloodstone, also known as heliotrope, is a cryptocrystalline variety of quartz, composed primarily of silicon dioxide (SiO₂). Its distinctive appearance—a dark green chalcedony base with vivid red spots of iron oxide (hematite)—has given rise to its name and a wealth of folklore.
Geological Formation and Sources
Bloodstone forms in volcanic or metamorphic environments, where silica-rich fluids deposit microcrystalline quartz. The red spots are inclusions of hematite, which were incorporated during the crystal's formation. The most prized bloodstones exhibit a deep, even green background with bright, contrasting red "drops" or "splashes." Major sources include India, which produces large quantities of bloodstone, as well as Australia, Brazil, China, and the United States (notably in California and Oregon). The quality of bloodstone can vary significantly, with the most valuable specimens having a uniform green color and well-defined, vibrant red inclusions.
Gemological Properties
As a form of chalcedony, bloodstone shares many properties with other quartz varieties like agate and onyx.
- Chemical Composition: SiO₂ (Silicon Dioxide) with inclusions of iron oxide (Fe₂O₃).
- Crystal System: Trigonal (microcrystalline).
- Hardness: 6.5 to 7 on the Mohs scale. This makes it durable enough for jewelry but slightly softer than aquamarine. It can be scratched by harder materials, so care should be taken.
- Refractive Index: 1.53 to 1.54.
- Specific Gravity: 2.58 to 2.64.
- Clarity: As an opaque to translucent stone, clarity is not assessed in the same way as transparent gems like aquamarine. The value is determined by the intensity and distribution of the red and green colors.
- Color: The classic bloodstone features a dark green base with red spots. Variations exist, including "plasma," which is a translucent green stone with no red spots, and "bloodstone," which is the opaque variety with red inclusions. The stone is generally not treated, as its value is derived from its natural color pattern.
Symbolism and Metaphysical Beliefs
Bloodstone's symbolism is deeply rooted in ancient lore and Christian tradition. Its most prominent association is with the crucifixion of Christ, where legend states that the stone was formed from the blood of Christ dripping onto the green earth at the foot of the cross. This connection made it a powerful symbol of martyrdom, sacrifice, and redemption. In ancient times, it was believed to have healing properties, particularly for blood-related ailments, and was worn as a talisman to stop bleeding and purify the blood. It was also considered a stone of courage and was used by warriors for protection in battle. For those born in March, bloodstone represents strength, resilience, and the ability to overcome adversity, linking the wearer to a long history of protective and healing beliefs.
Care and Cleaning
Bloodstone's care is straightforward due to its hardness and lack of cleavage. It can be cleaned with warm, soapy water and a soft cloth or brush. Avoid harsh chemicals and ultrasonic cleaners, as they could potentially damage the stone or loosen any inclusions. Like aquamarine, it should be stored away from harder gems to prevent scratching. Its durability makes it suitable for a variety of jewelry types, including rings, pendants, and bracelets.
Comparative Analysis: Aquamarine vs. Bloodstone
While both are birthstones for March, aquamarine and bloodstone are fundamentally different in almost every aspect, from their geological origin to their aesthetic appeal and cultural significance.
- Transparency and Color: Aquamarine is a transparent gem, prized for its clarity and uniform blue hue. Bloodstone is opaque to translucent, valued for its distinctive color pattern of green and red. This makes aquamarine ideal for faceted cuts that maximize light return, while bloodstone is typically cut en cabochon (a smooth, rounded dome) to showcase its color and pattern.
- Hardness and Durability: Aquamarine (7.5-8) is harder and more scratch-resistant than bloodstone (6.5-7). This gives aquamarine a slight edge for rings and bracelets that may encounter daily wear and tear, though both are durable enough for most jewelry applications.
- Symbolism: Aquamarine's symbolism is tied to the sea, water, and emotional calm, reflecting its color and name. Bloodstone's symbolism is darker and more intense, linked to blood, sacrifice, and protection, derived from its appearance and religious legends.
- Market Value and Availability: High-quality, large aquamarine crystals can be quite valuable, especially in deep, saturated colors. Bloodstone is generally more affordable and widely available, making it an accessible choice for those seeking a traditional birthstone with historical depth.
The choice between the two often comes down to personal preference: one may be drawn to the serene, clear beauty of aquamarine or the rugged, symbolic intensity of bloodstone. The modern birthstone chart accommodates this diversity by including both, allowing March-born individuals to select a stone that resonates with their personal style and beliefs.
