March is one of the few months associated with two distinct birthstones: aquamarine and bloodstone. These gemstones offer a compelling contrast in color, meaning, and energy—light blue aquamarine, symbolizing peace and clarity, and dark green bloodstone, representing strength and vitality. Each stone has a unique geological history, cultural significance, and set of properties that make them valuable not only in jewelry but also in metaphysical practices and historical traditions.
This article explores both March birthstones in depth, drawing from authoritative and well-documented sources to provide a comprehensive overview of their formation, symbolic meanings, and practical care. Whether you're a gemstone enthusiast, a jewelry buyer, or a student of gemology, this guide will offer insight into the enduring appeal of these two remarkable stones.
History and Lore
Aquamarine: The Sailor’s Stone
Aquamarine, with its calming blue-green hues, has long been revered for its protective qualities. Its name comes from the Latin aqua marinus, meaning “seawater,” and it was historically believed to be a gift from the sea. Ancient Greeks and Romans wore aquamarine as a talisman to protect sailors and ensure safe passage across the oceans. The gemstone was also associated with the sea god Poseidon, and it was thought that carrying aquamarine would appease him and calm turbulent waters.
The symbolism of aquamarine extended beyond maritime protection. In medieval Europe, the stone was believed to promote happiness in marriage and to bring clarity and courage to the wearer. Beryl, the mineral family to which aquamarine belongs, was thought to offer protection in battle and litigation and was believed to make the wearer amiable and "unconquerable." These beliefs reflect the gemstone’s enduring reputation as a stone of both strength and serenity.
Bloodstone: The Stone of Courage
In contrast to the serene aquamarine, bloodstone is a vibrant and powerful gemstone with a rich historical background. Known also as heliotrope, bloodstone is a form of chalcedony, a cryptocrystalline quartz. Its name derives from the dark green base and the flecks of red iron oxide that give it a striking appearance. These red spots are often interpreted as symbolic of life and vitality.
Bloodstone has a deeply rooted tradition in religious and symbolic contexts. One of the most famous historical accounts relates to the crucifixion of Christ. According to legend, bloodstone was formed when the Roman soldier’s spear pierced Christ’s side and his blood fell upon the dark green jasper at the foot of the cross. This story imbued the stone with powerful symbolism, linking it to sacrifice, healing, and spiritual strength.
The stone has also been used in religious carvings, with notable examples including a 16th-century sculpture by Italian artist Matteo del Nassaro. His work The Descent from the Cross features bloodstone to represent the blood of Christ, showcasing the gemstone's artistic and spiritual importance.
Both aquamarine and bloodstone have been valued across centuries for their protective and symbolic qualities, making them ideal choices for those born in March. While aquamarine offers a calming, tranquil energy, bloodstone brings a bold and energizing presence, together forming a perfect balance of peace and power.
Geological Formation and Sources
Aquamarine: A Beryl of the Sea
Aquamarine is a member of the beryl family, a mineral composed of beryllium, aluminum, silicon, and oxygen. It is typically found in granitic pegmatites and metamorphic rocks, where it forms as six-sided crystals. The gemstone's color is due to the presence of iron within the crystal structure—higher iron content results in a deeper blue hue.
The most prized aquamarine stones are those that exhibit a vivid blue color with minimal inclusions. These high-quality specimens are relatively rare, making them more valuable than their lighter or green-tinged counterparts. Aquamarine can also be heat-treated to enhance its color, a practice that has been used historically to convert yellow beryl into blue aquamarine.
The primary source of aquamarine today is Brazil, particularly in the states of Minas Gerais, Bahia, and Espírito Santo. Other notable sources include Colombia, Madagascar, India, and the Ural Mountains in Russia. In the United States, aquamarine can be found in Colorado, Maine, and North Carolina, though these deposits are less commercially significant.
Aquamarine is a durable gemstone, ranking between 7.5 and 8 on the Mohs hardness scale. This makes it suitable for use in a variety of jewelry applications, including rings, pendants, and bracelets. Its clarity and brilliance are often compared to that of diamonds, leading to its historical nickname, “the poor man’s diamond.”
Bloodstone: A Chalcedony of Life
Bloodstone, also known as heliotrope, is a form of chalcedony, a cryptocrystalline variety of quartz. It is composed primarily of silicon dioxide and is often found embedded in rocks or as pebbles in riverbeds. The dark green base of bloodstone is due to the presence of iron in the chalcedony, while the red flecks are iron oxide (hematite). These flecks give the stone its distinctive appearance and are often interpreted as symbolic of blood, hence the name.
The most important sources of bloodstone today are India, Brazil, and Australia. These countries produce the highest quality material, characterized by a deep green base and vibrant red spots. Bloodstone is also found in other parts of the world, but these regions typically yield lower-quality material.
Bloodstone ranks between 6.5 and 7 on the Mohs hardness scale, making it a moderately durable gemstone. While it is suitable for use in jewelry, it requires careful handling and cleaning to avoid damage. Bloodstone is often cut as a cabochon, which enhances its color and pattern, making it ideal for rings, pendants, and other types of jewelry.

Aquamarine is known for its clarity and brilliance, often resembling a clear, colorless diamond when cut. The most valuable specimens are those with a deep blue color and minimal inclusions. A notable optical phenomenon associated with aquamarine is pleochroism, where the gemstone appears to change color depending on the viewing angle. This effect can cause aquamarine to appear green, blue, or even colorless under certain lighting conditions.
Bloodstone

|---|---|
| Chemical Composition | Chalcedony (SiO₂) with iron oxide inclusions |
| Color | Dark green with red flecks |
| Hardness (Mohs) | 6.5–7 |
| Refractive Index | 1.53–1.54 |
| Specific Gravity | 2.58–2.64 |
| Transparency | Translucent to opaque |
| Luster | Waxy to vitreous |
| Common Cuts | Cabochon, oval |
| Primary Sources | India, Brazil, Australia |
Bloodstone is a relatively dense gemstone with a waxy to vitreous luster. It is often cut as a cabochon to showcase its unique pattern of red flecks against a dark green background. Unlike aquamarine, bloodstone does not exhibit pleochroism and has a more consistent appearance regardless of the viewing angle.
The presence of iron in bloodstone gives it a slight magnetic response, which can be useful in identifying the gemstone. It is also susceptible to damage from harsh chemicals and high temperatures, so care should be taken when cleaning or handling bloodstone jewelry.
