March is a unique month in the realm of birthstones, as it is associated with not one, but two gemstones: aquamarine and bloodstone. These stones differ greatly in appearance, symbolism, and history, yet both share a connection to strength, vitality, and the transition from winter to spring. This duality reflects the complexity and richness of gemstone traditions, which have evolved over centuries. This article explores the colors, origins, properties, and cultural significance of the March birthstones, offering a detailed understanding for gemstone enthusiasts, jewelry buyers, and students of gemology.
Introduction
March’s dual birthstones, aquamarine and bloodstone, represent a fascinating blend of colors and meanings. Aquamarine, with its serene blue hues, is often associated with calmness, courage, and protection during travel. Bloodstone, on the other hand, is a vivid green gemstone with red flecks, symbolizing vitality, healing, and resilience. Together, these stones capture the essence of March: the lingering winter, the promise of spring, and the enduring strength of the human spirit. This article delves into the geological, historical, and symbolic aspects of these stones, drawing on authoritative sources to provide an accurate and comprehensive overview.
History and Lore
The tradition of birthstones dates back to ancient times, with early references found in the 1st-century AD Biblical text, the Book of Exodus, which lists 12 stones for the 12 tribes of Israel. Over time, these stones were associated with the 12 months of the year and the zodiac signs. However, the exact identification of these ancient stones remains debated among scholars, as the names and descriptions in historical texts do not always align with modern gemstones.
In the case of March, bloodstone was originally the sole birthstone. This association dates back to medieval Europe, where bloodstone was believed to have protective and healing properties. By the 19th century, as gem identification and jewelry practices advanced, aquamarine was added to the list of March birthstones. This addition was partly driven by aquamarine’s increasing popularity in jewelry and its symbolic connection to spring and water.
The inclusion of both aquamarine and bloodstone in the modern March birthstone tradition reflects a broader cultural and historical evolution. Aquamarine, with its clear blue color, came to represent the "spring’s first waters," while bloodstone, with its earthy green and red hues, symbolized the "blood of the earth." This duality emphasizes the balance between the gentle and the robust, the fluid and the solid—key themes during the equinox.
Geological Formation and Sources
Aquamarine
Aquamarine is a member of the beryl family of minerals, which also includes emerald. Its blue color is caused by trace amounts of iron within the crystal structure. Aquamarine forms in igneous rocks, specifically in granite pegmatites and metamorphic rocks. It is typically found in large, well-formed crystals, which are then cut and polished into gemstones.
The primary sources of aquamarine are in South America, particularly Brazil, which is the largest supplier. Other notable sources include Nigeria, Pakistan, and Madagascar. These regions provide a wide range of aquamarine specimens, from pale, sky-blue stones to deep ocean blues. The availability of aquamarine in these locations contributes to its widespread use in jewelry and its relatively affordable price point compared to other precious gemstones.
Aquamarine is known for its durability, with a hardness of 7.5 to 8 on the Mohs scale. This makes it suitable for various types of jewelry, including rings, pendants, and earrings. Its transparency and glassy luster further enhance its appeal, making it a popular choice among jewelers and collectors.
Bloodstone
Bloodstone, also known as heliotrope, is a type of chalcedony, a microcrystalline variety of quartz. It is characterized by its deep green color, which is caused by the presence of chlorite or other green minerals, and red flecks, which are typically iron oxide inclusions. These red specks are often described as resembling drops of blood, which has contributed to the stone’s name and its historical associations with vitality and healing.
Bloodstone is primarily found in India, where it has been mined for centuries. Other sources include the United States, the United Kingdom, and parts of Europe. Unlike aquamarine, which is often cut into faceted gemstones, bloodstone is typically cut into cabochons, as its inclusions are more visible and do not lend themselves well to faceting. The stone’s opacity and the contrast between its green base and red flecks make it a striking choice for rings, pendants, and other forms of jewelry.
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, making it less durable than aquamarine. This means that bloodstone jewelry requires more careful handling, especially in rings that are worn daily. Despite this, its unique appearance and rich symbolism have made it a valued gemstone in both traditional and modern jewelry.
Gemological Properties
Aquamarine
Aquamarine is a beryl mineral, with the chemical formula Be₃Al₂(SiO₃)₆. It is known for its clarity and transparency, with colors ranging from pale blue to deep blue. The most valuable specimens are those with a pure blue color and minimal inclusions. The stone’s refractive index ranges from 1.56 to 1.60, and it exhibits strong double refraction, which can be observed in well-cut stones.
Aquamarine is pleochroic, meaning it can display different colors when viewed from different angles. This property is most noticeable in stones with a strong greenish hue, which may appear more blue or green depending on the direction of light. Aquamarine is also known for its excellent luster, which gives it a glassy, smooth appearance.
The stone’s durability is another key attribute. With a hardness of 7.5 to 8 on the Mohs scale, aquamarine is suitable for a wide range of jewelry applications. It is also relatively stable under normal conditions, though it can be sensitive to heat and light, which may cause fading in some cases.
Bloodstone
Bloodstone is a type of chalcedony, a microcrystalline quartz, with the chemical formula SiO₂. It is opaque or translucent, with a deep green color and red inclusions. The green color is due to the presence of chlorite or other green minerals, while the red flecks are typically iron oxide. The stone’s refractive index ranges from 1.53 to 1.54, and it exhibits a waxy or greasy luster.
Unlike aquamarine, bloodstone is not pleochroic. Its inclusions are more prominent, and its opacity makes it unsuitable for faceting. Instead, it is commonly cut into cabochons, which enhance its natural beauty and make it ideal for rings, pendants, and other forms of jewelry.
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, making it less durable than aquamarine. This means that bloodstone jewelry requires more careful handling, especially in rings that are worn daily. It is also sensitive to harsh chemicals and abrasives, which can damage its surface and dull its luster.
Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine has long been associated with the sea, and its blue color is often interpreted as a symbol of calmness, clarity, and serenity. In ancient times, sailors believed that aquamarine could protect them from storms and ensure safe passage across the oceans. This belief was based on the stone’s color and its association with water, which was seen as both a source of life and a force of nature.
In modern times, aquamarine is still valued for its calming properties. It is often used in meditation and spiritual practices to promote peace and emotional balance. Some people believe that aquamarine can help with communication, encouraging clear and honest expression. It is also associated with courage and confidence, making it a popular choice for those who want to overcome fear or self-doubt.
Aquamarine is also linked to the concept of eternal love and purity. Its clear, transparent nature is seen as a reflection of the heart and mind, symbolizing the ideal of a pure and unbreakable bond. This symbolism has made aquamarine a popular choice for engagement rings and other romantic jewelry.
Bloodstone
Bloodstone is a stone of vitality and strength. Its deep green color and red inclusions are often interpreted as a symbol of life and energy. In ancient times, bloodstone was believed to have healing properties and was used to treat wounds and other ailments. The red flecks were seen as the "blood of the earth," and the stone was thought to restore health and vigor to the body.
Bloodstone is also associated with courage and resilience. It is believed to help individuals overcome challenges and face difficult situations with determination and strength. This makes it a popular choice for those who want to build their confidence or support their personal growth.

Care and Cleaning
Aquamarine
Aquamarine is a relatively durable gemstone, but it still requires proper care to maintain its beauty and longevity. It is important to avoid exposing aquamarine to high temperatures or prolonged exposure to direct sunlight, as this can cause fading or discoloration. Aquamarine is also sensitive to certain chemicals, such as household cleaners and perfumes, which can dull its luster.
To clean aquamarine jewelry, it is best to use a soft cloth and mild soap. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the stone. When storing aquamarine jewelry, keep it in a cool, dry place away from other jewelry to prevent scratches and abrasions.
