March, a month of transition between winter and spring, is symbolized by two distinct yet equally meaningful gemstones: aquamarine and bloodstone. These birthstones represent not only the aesthetic and emotional resonance of the season but also centuries of history, cultural symbolism, and gemological significance. While aquamarine is celebrated for its tranquil blue hues and association with the sea, bloodstone stands as a bold, earthy counterpart with its deep green color and flecks of red iron oxide. Together, they form a dual birthstone tradition rooted in ancient lore and refined over centuries of cultural and commercial development.
This article explores the characteristics, history, and significance of both aquamarine and bloodstone as March birthstones. We will examine their geological properties, cultural symbolism, and their roles in jewelry and holistic practices. Drawing from a range of authoritative and historical sources, the article aims to provide a comprehensive overview for gemstone enthusiasts, collectors, and those curious about the deeper meaning behind these stones.
History and Lore
The tradition of associating gemstones with months and zodiac signs has a long and varied history, with roots in ancient civilizations. The earliest known references to birthstones can be traced back to the Biblical Breastplate of Aaron, described in the Book of Exodus, which lists twelve gemstones corresponding to the twelve tribes of Israel. Over time, these stones were interpreted as corresponding to the zodiac signs and later to the months of the year.
March, being the third month of the year, was traditionally linked to bloodstone in early birthstone lists. Ancient peoples, particularly the Greeks and Romans, believed that bloodstone was imbued with protective and healing properties. The name "bloodstone" is derived from the red iron oxide inclusions that resemble drops of blood scattered across a deep green background. These inclusions were thought to symbolize the blood of Christ or the lifeblood of warriors, and the stone was often used to treat wounds or to fortify the body and spirit.
However, the modern tradition of March having aquamarine as its primary birthstone developed much later. Aquamarine's association with March likely arose from its oceanic color and its growing popularity in jewelry during the 18th and 19th centuries. By the 19th century, aquamarine had become a widely recognized and valued gemstone, and it was eventually included in standardized birthstone lists. The inclusion of both aquamarine and bloodstone as March birthstones reflects a historical merging of old and new traditions, where the symbolic meanings of both stones were deemed relevant to the month.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of the mineral beryl, a beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. It belongs to the same mineral family as emerald, which is green due to chromium or vanadium impurities, whereas aquamarine gets its blue or blue-green color from iron impurities. Beryl typically forms in hydrothermal veins and granitic pegmatites, where it crystallizes slowly under high-temperature conditions.
The finest aquamarine deposits are found in:
- Brazil – particularly in the states of Minas Gerais and Bahia, which produce large, high-quality stones
- Madagascar – known for its vibrant blue aquamarine
- Nigeria – a significant source of aquamarine in Africa
- Uzbekistan – historically an important source
Aquamarine is generally transparent, with a glassy luster, and it is prized for its clarity and even color. It is also known for its pleochroism, an optical phenomenon in which the stone appears to change color depending on the angle of observation. Aquamarine is colorless in pure form, but the presence of iron gives it its characteristic blue or blue-green hue.
With a Mohs hardness of 7.5 to 8, aquamarine is durable enough for everyday jewelry, making it a popular choice for rings, pendants, and earrings. It is typically faceted to enhance its brilliance and color.
Bloodstone
Bloodstone, also known as heliotrope, is a type of chalcedony, a microcrystalline form of quartz. Its base color is a deep forest green, and it is characterized by red iron oxide inclusions that resemble drops of blood. These inclusions are not randomly distributed but often form distinct patterns, which can vary from a fine, scattered speckling to larger, more concentrated clusters.
Bloodstone is typically opaque, with a waxy to vitreous luster, and it is usually cut into cabochons rather than being faceted. This is because its inclusions and overall texture are better showcased in a smooth, rounded shape.
The primary sources of bloodstone are:
- India – the most significant and historic source, particularly in the state of Rajasthan
- Nepal – known for producing bloodstone with fine red inclusions
- Australia – produces a variety known as "Australian bloodstone"
- United States – particularly in the state of California, where it is found in jasper deposits
Bloodstone has a Mohs hardness of 6.5 to 7, which makes it suitable for jewelry, although it is more prone to scratches and abrasions than aquamarine. It is often used in pendants, rings, and signet rings, where its opaque nature and symbolic red inclusions are highlighted.

Bloodstone is valued for its distinctive appearance and the symbolic meaning of its red inclusions. The green base is due to the presence of chromite or other iron-bearing minerals, while the red spots are from hematite or goethite. Unlike aquamarine, bloodstone is not faceted because its inclusions and texture are best appreciated in a smooth, rounded shape.
Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine has long been associated with calmness, courage, and protection, particularly in maritime contexts. The name "aquamarine" itself derives from the Latin words "aqua" (water) and "marina" (of the sea), reflecting its deep connection to the ocean. In ancient times, sailors carried aquamarine to ward off tempests and ensure safe passage, believing it would calm the waves and appease the sea gods.
In addition to its maritime associations, aquamarine has also been linked to love and marriage. It was believed to foster harmony and happiness in relationships and to protect the wearer from betrayal or heartbreak. During the 19th century, it was even considered a symbol of fidelity and trust, making it a popular choice for wedding rings and anniversary gifts.
In modern metaphysical practices, aquamarine is associated with the Throat Chakra, which governs communication, self-expression, and truth. It is said to enhance clarity of thought, encourage honesty, and promote emotional healing. It is also believed to soothe anxiety and promote a sense of inner peace, making it a popular stone for meditation and spiritual practices.
Aquamarine is also considered a stone of youth and vitality, and it is often used in holistic healing to support thyroid function and respiratory health. Its calming energy is said to balance emotions and reduce stress, helping the wearer feel more centered and grounded.
Bloodstone
Bloodstone, with its deep green color and red inclusions, has long been associated with strength, vitality, and courage. The red iron oxide inclusions were believed to represent the lifeblood of warriors, and the stone was often used to fortify the body and spirit. In ancient times, it was considered a protective stone for soldiers and travelers, and it was believed to ward off physical and emotional harm.
One of the most notable historical uses of bloodstone was in religious and healing contexts. It was believed to purify the blood and promote physical healing, and it was often used in treatments for wounds, anemia, and other blood-related conditions. In medieval Europe, it was also used in signet rings, which were pressed into wax to seal important documents, symbolizing authority and power.
In modern metaphysical traditions, bloodstone is associated with the Root Chakra, which governs grounding, stability, and physical strength. It is said to enhance vitality, increase stamina, and promote a sense of inner strength. It is also believed to protect the wearer from negative energies and to encourage decisiveness and action.
Bloodstone is also considered a stone of justice and truth, and it is often used in legal and spiritual practices to enhance clarity of mind and promote fairness. It is also believed to support personal transformation and spiritual growth, helping the wearer to overcome obstacles and achieve their goals.
Care and Cleaning
Aquamarine
Aquamarine is relatively durable and easy to care for, but it does require some precautions to maintain its beauty and longevity. Because it has perfect basal cleavage, it can be damaged if struck along its cleavage plane, so it is best to avoid hard impacts.
Aquamarine should be cleaned with mild soap and warm water, using a soft brush to remove dirt and debris. It should be avoided from exposure to harsh chemicals, acids, and abrasive materials, as these can damage the surface or dull the luster.
When storing aquamarine jewelry, it is best to keep it in a soft pouch or a lined jewelry box to prevent scratches and abrasions. If you have multiple pieces, it is also a good idea to store them separately to avoid contact with harder gemstones like diamonds or sapphires.
Aquamarine is also non-reactive to sunlight, so it can be worn in daylight without concern. However, it is best to avoid prolonged exposure to extreme heat, as this can alter the color or cause stress in the crystal structure.
Bloodstone
Bloodstone is somewhat more delicate than aquamarine, with a lower hardness and a more porous surface. It is also more susceptible to scratches and abrasions, so it requires gentler care.
To clean bloodstone, use mild soap and warm water, and avoid harsh chemicals or abrasive materials. A soft cloth or soft-bristled brush can be used to remove dirt and debris, but be sure to avoid using anything that could scratch the surface.
Because bloodstone is opaque and has a waxy luster, it is best to avoid polishing it with traditional polishing agents, as this can alter its appearance or damage the inclusions. Instead, use a soft cloth to gently buff the surface and restore its shine.
When storing bloodstone jewelry, it is best to keep it in a dry, cool place, away from direct sunlight and extreme temperatures. It is also a good idea to store it in a separate compartment or pouch to prevent it from coming into contact with other gemstones, which can cause scratches or abrasions.
Bloodstone is also not recommended for use in ultrasonic or steam cleaners, as these can damage the surface or loosen the inclusions.
