The month of March is uniquely represented by two distinct and captivating gemstones: the serene, ocean-blue Aquamarine and the rugged, earthy Bloodstone. This duality offers those born in this transitional month a choice between tranquil waters and steadfast strength. While Aquamarine, with its clear, light-blue hue, is widely recognized as the primary modern birthstone, Bloodstone holds its place as a historic and powerful alternative. Together, they embody the spirit of March, bridging the final days of winter with the promise of spring. Their shared symbolism of courage, clarity, and perseverance makes them not only beautiful choices for jewelry but also profound tokens of meaning. This article will explore the rich history, geological origins, gemological properties, and cultural significance of both Aquamarine and Bloodstone, providing a comprehensive guide to the birthstones of March.
A Tale of Two Stones: History and Lore
The history of March's birthstones is a journey from ancient battlefields and stormy seas to modern jewelry cases. The association of these gems with the month dates back to traditional lists, but their individual stories are far older and deeply rooted in human culture.
Aquamarine: The Sailor's Talisman
The name Aquamarine is derived from the Latin words aqua meaning "water" and marina meaning "of the sea." This etymology perfectly encapsulates the gem's identity and its long-standing connection to maritime life. For centuries, Aquamarine was considered a treasure of the ocean, a talisman believed to ensure safe passage for sailors and protect them from the perils of the open water. Ancient lore held that this sea-blue stone was not merely a gem but a piece of the sea itself, solidified and brought to land.
Beyond its association with seafaring, Aquamarine has also been a symbol of courage, honesty, and loyalty. It was believed to bring these virtues to its wearer, making it a meaningful gift and a powerful personal emblem. Its serene color evokes a sense of calm and peace, and in modern metaphysical beliefs, it is said to reduce stress and quiet the mind, further enhancing its reputation as a stone of tranquility. Historically, it was also gifted to celebrate a 19th wedding anniversary, a testament to its enduring beauty and the loyalty it represents.
Bloodstone: The Martyr's Stone
In contrast to the ethereal quality of Aquamarine, Bloodstone is a gem of the earth, steeped in a history of courage and sacrifice. Also known as Heliotrope, this dark green chalcedony is distinguished by its striking inclusions of red iron oxide, which resemble drops of blood. This unique appearance gave rise to its powerful symbolism.
Bloodstone's history is particularly rich in Christian lore, where it became known as the "Martyr's Stone." Legend tells that the stone was formed at the foot of the cross, created from the blood of Christ dripping onto the green jasper below. This narrative imbued the stone with sacred significance, and it was often carved with scenes of the crucifixion. During the Middle Ages, it was not only a religious symbol but also a stone of warriors. It was believed to grant courage on the battlefield, stop bleeding from wounds, and invisibly heal its bearer. This association with strength and vitality has made Bloodstone a persistent symbol of perseverance and power throughout the ages.
The formal recognition of these two stones as March's birthstones evolved over time. Bloodstone was the original traditional birthstone for March. However, as Aquamarine grew in popularity and its sea-blue color became more sought after, it was added to the list, creating the dual-stone tradition that exists today.
Geological Formation and Global Sources
The origins of these two gemstones are as different as their appearances, one formed in the high-temperature veins of igneous rock and the other in the low-temperature deposits of ancient volcanic activity.
Aquamarine: A Beryl of the Pegmatites
Aquamarine is a variety of the mineral beryl, the same family that includes the emerald, morganite, and heliodor. Its beautiful blue to blue-green color is derived from trace amounts of ferrous iron within its chemical structure. The formation of large, gem-quality Aquamarine crystals requires specific geological conditions, typically found in pegmatites—coarse-grained igneous rocks formed from the slow cooling of magma deep within the Earth's crust.
Significant sources of Aquamarine are scattered across the globe. Notable mining locations mentioned in historical and gemological records include:
- Brazil: The primary source for modern Aquamarine, particularly the states of Minas Gerais and Bahia, which produce large, well-formed crystals.
- Africa: Countries such as Nigeria, Mozambique, Zambia, and Madagascar are also important producers, yielding high-quality stones.
- Pakistan: The Shigar Valley in the Gilgit-Baltistan region is renowned for its intensely blue Aquamarine crystals.
The finest Aquamarine is prized for its clear, bright blue shade and excellent transparency, with darker, more saturated blues generally commanding higher value.
Bloodstone: A Silicate of the Earth
Bloodstone is a variety of chalcedony, which is a microcrystalline form of quartz (silicon dioxide). Its chemical composition is primarily silica. The distinctive dark green color comes from the presence of hornblende or chlorite minerals, while the characteristic red speckles are caused by inclusions of iron oxides, such as hematite.
Unlike Aquamarine, which forms in high-temperature environments, Bloodstone is a low-temperature mineral. It is typically found in volcanic rocks, specifically as nodules or geodes within basalt flows. When these nodules are cut and polished, the unique distribution of green and red inclusions is revealed.
Historically, the finest Bloodstone was sourced from India. However, other locations have also produced this gem, including:
- Australia
- Brazil
- China
- United States (specifically Oregon)
The value of Bloodstone is often determined by the intensity of its green base color and the distinctness and distribution of its red "blood" droplets.
Gemological Properties: A Scientific Profile
Understanding the physical and chemical properties of a gemstone is crucial for both identification and appreciation. These properties dictate a stone's durability, appearance, and care requirements. While Aquamarine and Bloodstone are both birthstones for March, they differ significantly in their gemological makeup.
Aquamarine Properties
As a member of the beryl family, Aquamarine shares many characteristics with emeralds, but it is generally more included or "clean." Its properties make it a durable and desirable gem for all types of jewelry.
- Mineral Species: Beryl
- Chemical Composition: Be₃Al₂(SiO₃)₆, with trace amounts of iron (Fe²⁺ and Fe³⁺) for color
- Hardness (Mohs Scale): 7.5 to 8
- Crystal System: Hexagonal
- Refractive Index: 1.577 – 1.583
- Specific Gravity: 2.68 – 2.70
- Luster: Vitreous (glass-like)
- Transparency: Transparent to translucent
- Cleavage: Imperfect in one direction
The high hardness of Aquamarine (7.5-8 on the Mohs scale) makes it resistant to scratching and suitable for everyday wear in rings and bracelets. Its vitreous luster gives it a brilliant sparkle when properly cut.
Bloodstone Properties
Bloodstone, as a variety of chalcedony (quartz), has a different set of properties. It is typically cut en cabochon (a smooth, rounded dome) rather than faceted to best display its opaque body and the contrast of its inclusions.
- Mineral Species: Chalcedony (a variety of Quartz)
- Chemical Composition: SiO₂ (Silicon Dioxide), with inclusions of iron oxide (hematite) and hornblende/chlorite
- Hardness (Mohs Scale): 6.5 to 7
- Crystal System: Trigonal (microcrystalline)
- Refractive Index: 1.530 – 1.540
- Specific Gravity: 2.58 – 2.64
- Luster: Waxy to vitreous when polished
- Transparency: Opaque
- Cleavage: None (fracture is conchoidal)
With a hardness of 6.5 to 7, Bloodstone is still quite durable, though slightly less so than Aquamarine. Its opaque nature means it does not have the transparent brilliance of Aquamarine, but its unique patterns and rich color make it a favorite for bold, statement pieces.

Care and Cleaning for March Birthstones
Proper care is essential to maintain the beauty and longevity of any gemstone. Due to their differing hardness and clarity, Aquamarine and Bloodstone require slightly different approaches to cleaning and storage.
Caring for Aquamarine
With a hardness of 7.5 to 8, Aquamarine is quite durable and can be cleaned with relative ease. However, some stones may have liquid inclusions that can be damaged by heat or rapid temperature changes.
- Cleaning: The safest method is warm, soapy water with a soft brush. Rinse thoroughly to remove any soap residue. Avoid harsh chemicals and strong detergents.
- Ultrasonic and Steam Cleaners: Generally safe for Aquamarine, but it is wise to avoid them if the stone has visible inclusions or fractures, as the heat and vibrations could worsen them.
- Storage: Store Aquamarine separately from other gemstones to prevent scratching. A soft cloth or padded jewelry box is ideal.
Caring for Bloodstone
Bloodstone's hardness of 6.5 to 7 makes it moderately durable, but its opaque nature and potential for surface-reaching fractures require gentle handling.
- Cleaning: As with Aquamarine, warm, soapy water and a soft brush are the best choice. Avoid any harsh chemicals or acids, which could damage the stone's surface.
- Ultrasonic and Steam Cleaners: It is generally not recommended to use an ultrasonic cleaner or steam cleaner for Bloodstone. The vibrations of an ultrasonic cleaner can potentially dislodge the mineral inclusions that give the stone its color, and the high heat from a steamer can cause damage.
- Storage: Keep Bloodstone away from harder stones to prevent scratches. Given its use in cabochon cuts, it is also susceptible to chipping if struck against a hard surface, so store it carefully.
