March is unique among the months in the birthstone calendar, as it is associated with not one, but two gemstones: Aquamarine and Bloodstone. These stones have distinct appearances, histories, and symbolic meanings, yet both are celebrated for their protective and calming properties. While Aquamarine has become the more widely recognized and modern March birthstone, Bloodstone holds a rich tradition and continues to be appreciated for its strength and vitality. Together, they offer a fascinating duality that reflects both the gentle transition from winter to spring and the diverse personality traits of those born in March.
This article explores the history, gemological properties, cultural significance, and practical care of these two stones. Drawing from a range of sources, it presents a comprehensive overview of the dual birthstones of March, offering insights into their origins, symbolism, and enduring appeal in the world of gemstones.
History and Lore
The tradition of associating gemstones with specific months of the year has a long and varied history. While modern birthstone charts typically designate Aquamarine as the official March birthstone, the use of Bloodstone in this context dates back to older traditions. These two stones have been treasured for centuries, each with its own set of legends and meanings.
Aquamarine, the more prominent of the two, has a rich history that dates back to ancient civilizations. The name "Aquamarine" is derived from the Latin words aqua (water) and marina (sea), a fitting name for a gemstone that resembles the colors of the ocean. Ancient sailors believed that Aquamarine would protect them during sea voyages, and it was often carried as a talisman to ward off danger. The Romans used Aquamarine in amulets to mend relationships and strengthen friendships. In ancient Egypt, it was believed to symbolize joy and youth, and it was often used in jewelry to represent these qualities. Over time, Aquamarine became associated with calmness, clarity, and communication, and it has become a popular gemstone in modern jewelry design.
Bloodstone, on the other hand, has a more varied and sometimes darker history. The name "Bloodstone" refers to the red flecks that appear in the deep green base of the stone, which are caused by iron oxide. These flecks resemble drops of blood, and in medieval Europe, Bloodstone was often associated with religious and healing symbolism. Some traditions held that the red spots represented the blood of Christ, and the stone was used in religious artifacts and amulets. Bloodstone was also believed to have healing properties, particularly in relation to the circulatory system and vitality. In some cultures, it was thought to bring courage and strength to the wearer, making it a popular stone for warriors and those seeking protection in battle.
The coexistence of these two gemstones in the March birthstone tradition is somewhat unique. While Aquamarine has gained more popularity in modern times, Bloodstone continues to be recognized as an important stone in traditional birthstone lore. This duality reflects the broader tradition of birthstones, which often includes both modern and historical designations. The inclusion of both Aquamarine and Bloodstone in the March birthstone list highlights the richness of gemstone symbolism and the diverse ways in which different cultures have interpreted the meaning of these stones over time.
Geological Formation and Sources
Aquamarine and Bloodstone are both naturally occurring gemstones, but they form under very different geological conditions and are found in different parts of the world.
Aquamarine
Aquamarine is a variety of the mineral beryl, which also includes emerald. It forms in granitic pegmatite deposits, which are igneous rocks that crystallize from magma. The blue color of Aquamarine is caused by trace amounts of iron within the crystal structure. Aquamarine is typically found in alluvial deposits, where it has been eroded from its original source and deposited in riverbeds or sedimentary rock. This is why many of the most famous Aquamarine deposits are found in alluvial gravel rather than in the original pegmatite.
The most important sources of Aquamarine today include Brazil, Madagascar, Nigeria, and Afghanistan. Brazil has been a major producer of Aquamarine for many years, particularly in the state of Minas Gerais, where some of the largest and finest stones have been found. Madagascar is another significant source, known for producing Aquamarine with a very pale blue color. Nigeria and Afghanistan also contribute to the global supply of Aquamarine, with each country producing stones with slightly different characteristics.
Aquamarine is relatively hard, with a hardness of 7.5 to 8 on the Mohs scale, making it durable enough for use in jewelry. It is also known for its excellent clarity, with many stones being nearly free of inclusions. This combination of hardness and clarity makes Aquamarine a popular choice for rings, pendants, and other types of jewelry.
Bloodstone
Bloodstone, also known as heliotrope, is a type of chalcedony, which is a microcrystalline variety of quartz. It is characterized by its deep green base color and the red flecks that give it its distinctive appearance. The green color comes from chlorite or other green minerals, while the red flecks are caused by iron oxide.
Bloodstone is typically found in metamorphic and sedimentary rocks, and it is most commonly found in India, Poland, and the United States. India is the largest producer of Bloodstone, particularly in the state of Rajasthan, where it is mined from sedimentary deposits. Poland has also been a historical source of Bloodstone, and it was especially valued during the Renaissance period. In the United States, Bloodstone has been found in various locations, including Pennsylvania and New York.
Bloodstone is a relatively hard gemstone, with a hardness of 6.5 to 7 on the Mohs scale. It is often cut as a cabochon rather than being faceted, which allows the red flecks to be evenly distributed across the surface of the stone. This type of cutting also enhances the stone's luster and makes it more visually appealing. Bloodstone is often used in rings, pendants, and other types of jewelry, and it has a long history of use in religious and decorative artifacts.
Gemological Properties
The gemological properties of Aquamarine and Bloodstone are quite different, reflecting their distinct mineral compositions and formation processes. These properties influence how the stones are used in jewelry and how they are cared for.
Aquamarine
Aquamarine is a beryl, which is a beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. It belongs to the hexagonal crystal system and is known for its excellent clarity and transparency. Aquamarine has a refractive index of 1.57 to 1.58, which gives it a moderate dispersion and a soft, glassy luster.
The most distinctive feature of Aquamarine is its color, which ranges from a pale, almost colorless blue to a deep, intense blue. The blue color is caused by the presence of iron in the crystal structure. Some Aquamarines also have a slight greenish tint, which is due to the presence of iron and the way the light interacts with the crystal. High-quality Aquamarines are those that have a pure blue color and minimal inclusions.
Aquamarine has a hardness of 7.5 to 8 on the Mohs scale, which makes it relatively durable and suitable for use in jewelry. It is also resistant to most types of damage, although it can be scratched by harder materials such as diamonds. Aquamarine is often heat-treated to enhance its color, and this treatment is stable and does not fade over time.

Bloodstone
Bloodstone is a type of chalcedony, which is a microcrystalline variety of quartz. It has the chemical formula SiO₂ and belongs to the trigonal crystal system. It is a translucent to opaque stone with a waxy to vitreous luster.
The most distinctive feature of Bloodstone is its deep green color and the red flecks that are caused by iron oxide. The green color comes from chlorite or other green minerals, and the red flecks are usually concentrated in certain areas of the stone. High-quality Bloodstone has a uniform green base and evenly distributed red flecks.
Bloodstone has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable. However, it is more prone to chipping than Aquamarine due to its microcrystalline structure. It is often cut as a cabochon rather than being faceted, which allows the red flecks to be evenly distributed across the surface of the stone.
