The month of March is uniquely represented in the world of gemstones by two distinct and compelling stones: Aquamarine and Bloodstone. Unlike months with a single birthstone, March offers a duality of color, history, and meaning. These two gems—one celebrated for its serene, oceanic blue and the other for its deep, earthy green flecked with red—provide a rich tapestry of options for those born in this transitional month. While modern lists often prioritize Aquamarine, the traditional significance of Bloodstone remains deeply rooted in historical lore. This article provides a comprehensive exploration of both March birthstones, detailing their geological origins, gemological properties, historical journeys, and the symbolic meanings that have made them enduring favorites.
Aquamarine, a member of the beryl family, is the primary modern birthstone for March. Its name, derived from the Latin words aqua (water) and marina (sea), perfectly encapsulates its signature color, which ranges from pale, almost ethereal blue to deep, saturated shades reminiscent of the open ocean. This gem is prized for its remarkable clarity and durability, making it a favored choice for a wide array of jewelry. Historically, it has been associated with sailors, who believed it offered protection and ensured safe passage across treacherous waters. Its calming energy is also linked to clarity of thought and emotional balance.
In contrast, Bloodstone, also known as heliotrope, stands as the traditional birthstone for March. It is a cryptocrystalline variety of quartz, characterized by its dark green chalcedony base interspersed with vibrant red spots of iron oxide. This striking appearance has led to a wealth of symbolism, with ancient warriors believing the stone could staunch wounds and grant them courage in battle. Its lore is tied to strength, vitality, and resilience. The coexistence of these two stones allows individuals born in March to choose a gem that resonates with their personal style and the specific qualities they wish to embody—be it the calm, communicative nature of Aquamarine or the bold, protective strength of Bloodstone. This guide will delve into the individual histories, sources, properties, and care instructions for each, offering a complete overview for gemstone enthusiasts, collectors, and anyone captivated by the allure of March's birthstones.
Aquamarine: The Primary March Birthstone
Aquamarine is the most widely recognized birthstone for March, celebrated for its captivating sea-blue hues and exceptional clarity. As a member of the beryl mineral family, it is a close relative of other well-known gems like emerald (green beryl), morganite (pink beryl), and heliodor (yellow beryl). Its chemical composition is beryllium aluminum cyclosilicate, and its signature color is primarily caused by trace amounts of iron within its crystal lattice. The intensity of the blue can vary significantly, with the most valued specimens exhibiting a deep, saturated blue with minimal greenish undertones. The gem's name is a direct nod to its color inspiration, originating from the Latin aqua marinus, meaning "water of the sea." This connection to the ocean has defined its cultural and symbolic identity for centuries.
History and Lore of Aquamarine
The history of Aquamarine is rich with maritime lore and beliefs in its protective powers. Ancient mariners, including the Greeks and Romans, wore this gem as an amulet to protect themselves from the perils of the sea. They believed that Aquamarine was a treasure of mermaids and that it possessed the power to calm waves and ensure a safe voyage. This belief was so pervasive that the gem was often carried by sailors as a lucky charm to protect against drowning and to bring good fortune. Beyond its connection to the sea, Aquamarine was also believed to have other protective qualities. It was thought to give the wearer protection against foes in battle and in legal disputes. Some ancients also believed the stone could make the wearer unconquerable, amiable, and quicken the intellect.
The lore surrounding Aquamarine extends to matters of the heart and mind. It was believed to bring happiness in marriage and to foster a harmonious relationship between partners. In more recent history, Aquamarine has been associated with the 19th wedding anniversary, solidifying its status as a gem of enduring love and commitment. One of the most famous examples of Aquamarine is the 1,298-carat rectangular step-cut stone presented to First Lady Eleanor Roosevelt by the government of Brazil in 1936, which remains a testament to the gem's impressive size and beauty.
Geological Formation and Sources
Aquamarine forms in pegmatites, which are coarse-grained igneous rocks that provide the ideal environment for large, well-formed crystals to grow. These geological formations allow beryl crystals to develop over millions of years, often reaching impressive sizes. Major sources for high-quality Aquamarine are concentrated in a few key regions around the world.
Brazil is the leading producer of Aquamarine, known for yielding large crystals with the deep blue color for which the stone is prized. Other significant sources include Pakistan, particularly the Skardu region, which produces stones with a rich, saturated color. Madagascar is another important source, contributing a substantial amount of the global supply. Other localities, such as Nigeria, Mozambique, and parts of the United States (specifically Maine and North Carolina), also produce Aquamarine, though often in smaller quantities or with different color characteristics.
Gemological Properties of Aquamarine
Aquamarine possesses a combination of properties that make it both beautiful and durable for jewelry use. Its hardness, clarity, and color are its most defining characteristics.
- Hardness: On the Mohs scale of hardness, Aquamarine rates between 7.5 and 8. This makes it a relatively hard and durable gemstone, suitable for all types of jewelry, including rings and bracelets that are subject to daily wear. It is more durable than many other popular colored stones, such as opal or turquoise.
- Clarity: One of Aquamarine's most appealing qualities is its clarity. Faceted aquamarines are often free from visible inclusions, giving them a "water-clear" appearance that symbolizes purity. While inclusions can be present, they typically do not diminish the stone's beauty to the same extent as in other gems.
- Color: The color of Aquamarine ranges from light, slightly greenish blue to deep green-blue. The most prized color is a clear, bright, deep blue with no greenish tint.
- Crystal System: It belongs to the hexagonal crystal system.
- Specific Gravity: Its specific gravity typically ranges from 2.68 to 2.80.
- Refractive Index: The refractive index of Aquamarine falls between 1.577 and 1.583.

Bloodstone: The Traditional March Birthstone
Bloodstone, also known as heliotrope, is the traditional birthstone for March and offers a striking contrast to the serene blue of Aquamarine. It is a variety of cryptocrystalline quartz, composed of microscopically fine crystals of silicon dioxide. Its defining characteristic is its deep, earthy green chalcedony base, which is vividly spotted or streaked with red iron oxide inclusions. These red markings are the source of its evocative name and much of its symbolic power. The appearance of Bloodstone is often described as rustic and powerful, making it a popular choice for those who prefer bold, unique jewelry. While Aquamarine is often faceted to highlight its clarity, Bloodstone is typically cut en cabochon (a smooth, polished dome) to best display its rich color and the dramatic contrast between the green and red.
History and Lore of Bloodstone
The lore surrounding Bloodstone is ancient and deeply connected to themes of strength, health, and courage. Its most famous association is with the Christian legend of the Crucifixion. It is said that the blood of Christ fell upon a green jasper stone at the foot of the cross, and the drops of blood miraculously stained the stone, creating the red specks seen in Bloodstone today. This connection gave the stone its religious significance and led to its use in carving scenes of the crucifixion and martyrdom.
In the ancient world, Bloodstone was known as the "martyr's stone." It was believed to have the power to staunch bleeding and was worn as an amulet to protect against wounds. Ancient warriors carried it into battle, believing it would heal them if they were injured and grant them courage and victory. Its reputation as a healing stone extended beyond physical wounds; it was also thought to purify the blood and support overall health and vitality. The name "heliotrope," derived from Greek words meaning "sun" and "to turn," reflects an ancient belief that the stone could turn the sun red by its influence, or that it could be used to find gold.
Geological Formation and Sources
Like other forms of chalcedony, Bloodstone is a microcrystalline variety of quartz that forms in volcanic or metamorphic rocks. The green color comes from the presence of actinolite or chlorite inclusions, while the red spots are caused by iron oxide (hematite). Bloodstone is found in various locations around the world. Major sources include India, which is known for producing large quantities of high-quality Bloodstone. Other significant deposits are found in Australia, Brazil, China, and parts of Europe such as the Czech Republic. It is also found in the United States.
Gemological Properties of Bloodstone
Bloodstone's properties are characteristic of chalcedony, making it a durable and versatile gem, though with different characteristics than Aquamarine.
- Hardness: Bloodstone rates between 6.5 and 7 on the Mohs scale. This makes it a reasonably durable stone, suitable for jewelry, but it is slightly softer than Aquamarine and can be more susceptible to scratching if not handled with care.
- Clarity and Appearance: As a cryptocrystalline stone, Bloodstone is opaque. Its beauty lies in its rich color and the distribution of the red iron oxide inclusions. The most prized stones have a deep, uniform green background with bright, distinct red spots.
- Color: The primary color is a dark, leek-green chalcedony, with red or orange-red spots.
- Luster: It typically has a vitreous (glassy) to waxy luster when polished.
- Composition: Chemically, it is silicon dioxide (SiO₂), the same as all quartz, but its appearance is defined by the included minerals.
Symbolism and Metaphysical Beliefs
The symbolism attached to the March birthstones is as distinct as their appearance. Aquamarine is overwhelmingly associated with qualities of calmness, clarity, and protection, particularly in relation to water. Its calming blue hues are believed to soothe the spirit, reduce stress, and promote inner peace. In the realm of crystal healing, it is considered a stone of communication, said to enhance clarity of thought and self-expression, making it a valuable tool for public speakers and those seeking to articulate their feelings. Its connection to the sea lends it a powerful protective quality, guarding travelers and those who work on or near the water.
Bloodstone, in contrast, embodies vitality, strength, and courage. Its symbolism is more active and assertive. It is known as the "stone of courage" and is believed to imbue its wearer with bravery, strength, and the ability to overcome challenges. Its historical use as a healing stone continues in modern metaphysical beliefs, where it is thought to purify the blood, boost the immune system, and revitalize the body and mind. Bloodstone is also associated with wealth and abundance, and it is said to help one make decisive choices and bring success in competitive situations. The choice between these two stones often reflects the personal attributes an individual wishes to cultivate—either the serene, reflective qualities of Aquamarine or the dynamic, resilient nature of Bloodstone.
Choosing and Caring for March Birthstones
When selecting between Aquamarine and Bloodstone, the choice often comes down to personal preference for color, style, and the symbolic meaning that resonates most. Aquamarine, with its brilliant facets and transparent clarity, is ideal for elegant, classic jewelry such as engagement rings, pendants, and earrings. Its hardness makes it a practical choice for everyday wear. Bloodstone, with its opaque, earthy character, is often fashioned into cabochon rings, bracelets, and beads, offering a more rustic or bold aesthetic. It is well-suited for statement pieces and is favored by those who appreciate grounded, historical gemstones.
Proper care is essential to maintain the beauty of these stones. Due to their differing hardness and clarity, they require slightly different handling.
Cleaning Aquamarine: With a hardness of 7.5-8 and excellent clarity, Aquamarine is relatively easy to care for. It can be cleaned safely with warm water, a mild soap, and a soft brush. It is important to rinse it thoroughly to remove any soap residue. Ultrasonic and steam cleaners are generally safe for Aquamarine, but it is always wise to inspect the stone for any fractures before using these methods. Avoid sudden temperature changes.
Cleaning Bloodstone: As a variety of quartz with a hardness of 6.5-7, Bloodstone is more susceptible to scratches than Aquamarine. It is best cleaned with warm, soapy water and a soft cloth. Avoid harsh chemicals and abrasive cleaners. While it is relatively durable, it is not recommended to use an ultrasonic cleaner, especially if the stone has been treated or has fractures. The best practice is gentle hand washing.
For both stones, it is advisable to store them separately from other jewelry to prevent scratching. Keeping them away from prolonged exposure to intense heat or direct sunlight can also help preserve their color over time.
