March is symbolized by two distinct yet equally compelling birthstones: aquamarine and bloodstone. While aquamarine is celebrated for its serene blue hues and association with calmness and clarity, bloodstone is revered for its deep green color with red inclusions and its historical ties to strength and vitality. This article delves into the geological, historical, and cultural significance of these two gemstones, focusing on their roles as charms and jewelry pieces, their symbolic meanings, and their enduring appeal in both traditional and modern contexts.
History and Lore
The use of aquamarine as a gemstone dates back to ancient times, with its name derived from the Latin aqua marina, meaning "seawater." Ancient mariners believed aquamarine had the power to calm the waves and protect sailors from the dangers of the sea. This belief led to the stone being carried by seafarers as a talisman for safety during long voyages. In medieval Europe, aquamarine was thought to bring happiness in marriage and was also associated with intellectual clarity, making it a favored gemstone among scholars and warriors alike.
In contrast, bloodstone, also known as heliotrope, has a more somber and earthy history. The gemstone is a variety of chalcedony (a type of cryptocrystalline quartz) that is typically dark green with red inclusions of iron oxide, often hematite. Its name, bloodstone, stems from its appearance, which has been interpreted as symbolizing the blood of Christ in some religious traditions. Another historical belief held that the stone could turn the sun red when placed in water, giving rise to its alternate name heliotrope, derived from the Greek helios (sun) and tropos (turning).
Both aquamarine and bloodstone have been used in jewelry and amulets throughout history. Aquamarine, with its clear and vibrant blue color, was prized for its beauty and was often used in royal and noble settings. Bloodstone, on the other hand, was more commonly used in pendants and rings, especially among those seeking physical and mental fortitude. In India, bloodstone continues to be valued for its supposed aphrodisiac qualities when ground into a powder.
In modern times, both gemstones have retained their symbolic significance. Aquamarine is often associated with serenity and purity, while bloodstone is seen as a symbol of courage and vitality. These meanings have been embraced in contemporary jewelry design, particularly in the form of charms and pendants that serve as personal adornments and meaningful gifts.
Geological Formation and Sources
Aquamarine
Aquamarine is a beryl mineral, chemically composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆). Its color, ranging from light blue to deep blue-green, is caused by trace amounts of iron within the crystal structure. The most valuable aquamarines are those with a vivid blue color and high transparency.
The formation of aquamarine occurs in pegmatite deposits, which are igneous rocks formed from the slow cooling of magma. These deposits are rich in rare elements and create the ideal conditions for the growth of large, well-formed crystals. Brazil has long been the primary source of aquamarine, particularly the state of Minas Gerais, where the gemstone has been mined for centuries. Other significant sources include Nigeria, Madagascar, and the United States.
Aquamarine is typically cut into faceted gemstones, which enhance its brilliance and clarity. The most famous aquamarine in the world is the Dom Pedro Aquamarine, housed at the Smithsonian Institution in Washington, D.C. This massive gemstone, weighing 10,363 carats, was cut by renowned German lapidary Berndt Munsteiner using the fantasy cut technique. Another notable aquamarine is the 1,298-carat stone presented to First Lady Eleanor Roosevelt in 1936 by the government of Brazil.
Bloodstone
Bloodstone, a type of chalcedony, is composed of silicon dioxide (SiO₂) with inclusions of iron oxide. Its dark green color is due to the presence of chlorite or other green minerals, while the red inclusions are typically hematite. The formation of bloodstone occurs in sedimentary rocks, where chalcedony deposits mix with iron-rich minerals.
Historically, bloodstone was found in the Indian subcontinent, particularly in the region of India and Pakistan. Today, bloodstone is also mined in Europe, including in Germany, France, and the Czech Republic. The gemstone is typically cut as a cabochon, which showcases its inclusions and gives it a smooth, rounded appearance. Faceted bloodstone is rare, as the material is often opaque and not suited for faceting.
Gemological Properties
| Property | Aquamarine | Bloodstone |
|---|---|---|
| Chemical Formula | Be₃Al₂(SiO₃)₆ | SiO₂ (with iron oxide inclusions) |
| Color | Blue to blue-green | Dark green with red inclusions |
| Hardness (Mohs) | 7.5–8 | 6.5–7 |
| Specific Gravity | 2.66–2.83 | 2.58–2.64 |
| Refractive Index | 1.56–1.60 | 1.48–1.53 |
| Luster | Vitreous | Waxy to dull (cabochons) |

| Cleavage | None | None |
| Inclusions | Rare | Common (iron oxide) |
Aquamarine is a relatively durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale. Its high clarity and transparency make it ideal for faceting, and it is often used in rings, pendants, and earrings. The gemstone's vitreous luster enhances its brilliance and makes it a popular choice for fine jewelry.
Bloodstone, while slightly less hard than aquamarine, is still a durable gemstone with a hardness of 6.5 to 7. It is typically cut as a cabochon, which gives it a smooth, rounded surface that enhances the visibility of its inclusions. The waxy to dull luster of bloodstone is not as bright as aquamarine, but it complements its earthy appearance and symbolic meaning.
Both gemstones are resistant to cleavage, making them suitable for everyday wear. However, care should be taken to avoid exposure to harsh chemicals and extreme temperatures, which can affect their appearance and durability over time.
Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine is often associated with calmness, clarity, and purity. In ancient times, it was believed to protect sailors from the dangers of the sea and to bring peace and harmony to the wearer. These beliefs have carried over into modern times, where aquamarine is seen as a stone of serenity and emotional balance.
Metaphysically, aquamarine is thought to enhance communication, both verbal and non-verbal. It is believed to promote clear thinking and to help individuals express their thoughts and emotions with confidence and ease. The gemstone is also associated with courage, particularly in times of fear or uncertainty. As a birthstone for March, it is often given as a gift to those seeking emotional strength and inner peace.
Bloodstone
Bloodstone, with its dark green color and red inclusions, is a symbol of strength, vitality, and protection. In ancient times, it was believed to increase physical strength and to help warriors in battle. These beliefs have persisted into modern times, where bloodstone is often used by athletes and others who seek to improve their physical and mental endurance.
The gemstone is also associated with healing and is believed to promote good health and longevity. In medieval Europe, it was used in amulets to protect against disease and to aid in the recovery of the sick. The red inclusions, resembling drops of blood, have led to the belief that bloodstone can stimulate the circulatory system and enhance overall vitality.
In India, bloodstone continues to be valued for its aphrodisiac properties when ground into a powder. It is also believed to bring good luck and to help individuals overcome obstacles and challenges.
Care and Cleaning
Both aquamarine and bloodstone are relatively durable gemstones, but they require proper care to maintain their beauty and longevity. Aquamarine, with its high hardness and transparency, can be cleaned using warm water and mild soap. It is important to avoid exposure to harsh chemicals, such as chlorine and bleach, which can damage the gemstone's surface and clarity.
Bloodstone, being a slightly softer gemstone, should also be cleaned with care. While it can be cleaned using warm water and mild soap, it is not recommended to use ultrasonic or steam cleaners, as these can cause the inclusions to shift or become damaged. Bloodstone should also be stored separately from other gemstones to avoid scratches or abrasions.
When wearing jewelry made with aquamarine or bloodstone, it is important to avoid contact with perfumes, hairsprays, and other chemicals, as these can dull the gemstone's luster and affect its appearance. It is also advisable to remove the jewelry before engaging in activities that may cause physical impact or abrasion.
