The month of March is uniquely represented in the world of birthstones by two distinct gems: Aquamarine and Bloodstone. While modern conventions predominantly favor the serene blue of Aquamarine, the traditional heritage of March also embraces the deep, earthy tones of Bloodstone. Together, they offer a fascinating study in contrast—one reflecting the calm of the sea, the other the vitality of life. This duality provides those born in March with a rich palette of choices, each carrying deep historical significance and distinct gemological characteristics.
The primary birthstone, Aquamarine, is celebrated for its light blue to blue-green hues, evoking the tranquil waters of the ocean. Its name, derived from the Latin aqua marina meaning "water of the sea," perfectly encapsulates its appearance and lore. Historically, it has been a talisman for sailors and a symbol of courage and clarity. The alternative stone, Bloodstone, is a variety of chalcedony known for its dark green body color splashed with red iron oxide inclusions. It carries a legacy of strength and perseverance, deeply rooted in ancient lore.
This article will explore the comprehensive history, geological origins, and specific gemological properties of these two March birthstones. We will examine their journey to becoming official birthstones, the locations where they are mined, and the practical considerations for their care and maintenance.
History and Lore: From Ancient Talismans to Modern Birthstones
The designation of birthstones for each month has evolved over centuries, influenced by biblical texts, trade traditions, and modern marketing. For March, the journey involves both ancient protective amulets and the establishment of a standardized list for jewelry consumers.
The Ascendancy of Aquamarine
Aquamarine’s status as the primary modern birthstone for March is well-documented in contemporary sources. It is consistently listed as the official gemstone for the month, symbolizing serenity, courage, and renewal. Its association with the ocean is not merely descriptive but deeply historical. Ancient lore held that Aquamarine was a treasure of mermaids and was carried by sailors as a protective talisman against the perils of the sea. The stones were believed to calm waves and ensure a safe voyage.
Beyond its nautical connections, Aquamarine has also been linked to marital happiness. Sources note that it is traditionally given to celebrate the 19th wedding anniversary, cementing its role as a gemstone of enduring love and loyalty. The transition of Aquamarine to the top of the March list reflects a preference for its aesthetic appeal and clarity, which aligns with modern gemological standards.
The Traditional Roots of Bloodstone
While Aquamarine dominates the modern lists, Bloodstone holds the position of the traditional or alternative March birthstone. Also known as heliotrope, Bloodstone is a cryptocrystalline quartz. Its history is steeped in symbolism regarding strength and perseverance. In ancient times, it was believed to have healing properties and was often ground into powder for medicinal use.
The most prominent legend associated with Bloodstone connects it directly to the crucifixion of Christ. According to Christian lore, the stone was formed when the blood of Jesus dripped onto the green jasper at the foot of the cross. This origin story imbued the stone with sacred significance, and it became a popular amulet for warriors and those seeking protection in battle. Despite its lack of the "blue" color typically associated with March, Bloodstone is included in official charts to honor the historical lineage of birthstones, often dating back to the breastplate of Aaron described in the Bible.
Geological Formation and Mining Sources
Understanding where these gems originate provides insight into their value and availability. While both are minerals, their formation processes and geographic distribution differ significantly.
Aquamarine: The Beryl Giant
Aquamarine is a member of the beryl family, making it a mineralogical cousin to emerald and morganite. Its chemical composition is beryllium aluminum cyclosilicate. The characteristic blue-to-blue-green color is caused by trace amounts of ferrous iron within the crystal lattice.
The formation of Aquamarine occurs within igneous and metamorphic rocks, specifically in pegmatites—coarse-grained intrusive rocks that allow for the growth of large, well-formed crystals. These geological conditions are found in several key regions globally:
- Brazil: As the world's largest supplier, Brazil produces high-quality Aquamarine in states like Minas Gerais and Rio Grande do Norte.
- Pakistan: The Skardu region is renowned for producing deeply colored Aquamarine crystals.
- Africa: Nigeria and Madagascar are significant sources, contributing to the global supply with stones that often exhibit lighter, more delicate hues.
The widespread availability of Aquamarine, combined with the potential for finding large, clean crystals, makes it accessible to a wide range of buyers.
Bloodstone: The Silica Variety
Bloodstone is not a beryl but a variety of chalcedony, which is a microcrystalline form of quartz (silicon dioxide). It is characterized by its deep green body color, derived from hornblende or chlorite inclusions, and distinct red spots of iron oxide (jasper).
Unlike the crystalline structure of Aquamarine, Bloodstone forms in massive habits, often within volcanic or metamorphic rocks. It is found in various locations, though specific mining regions are less frequently highlighted in general birthstone literature compared to Aquamarine. However, it is known to be sourced from India, Australia, Brazil, and parts of Africa. Its durability and opaque nature make it suitable for carving and cabochon cuts rather than faceted gems.
Gemological Properties: A Scientific Comparison
For gemologists and jewelry buyers, the physical properties of a stone dictate its durability, brilliance, and care requirements. Aquamarine and Bloodstone differ significantly in these aspects.
Aquamarine Properties
Aquamarine is prized for its transparency and vitreous luster. It is a relatively hard and durable gemstone, making it excellent for rings, pendants, and earrings.
- Hardness: It rates between 7.5 and 8 on the Mohs scale, indicating good resistance to scratching.
- Chemical Composition: Be₃Al₂Si₆O₁₈ (Beryl).
- Refractive Index: 1.577 to 1.583 (Uniaxial negative).
- Crystal System: Hexagonal.
- Color: Ranges from pale blue to blue-green and greenish blue. The most valued colors are the deep, pure blue of Santa Maria or the lighter, airy "Sky Blue."
Bloodstone Properties
Bloodstone is an opaque gemstone valued for its color contrast and toughness.
- Hardness: It rates 6.5 to 7 on the Mohs scale, slightly softer than Aquamarine but still durable enough for daily wear.
- Chemical Composition: SiO₂ (Quartz/Chalcedony).
- Refractive Index: Approximately 1.53 to 1.54.
- Crystal System: Trigonal (microcrystalline).
- Color: Dark green with red inclusions (often called "blood" spots).
The following table summarizes the key differences between the two March birthstones based on the provided data:

Symbolism and Metaphysical Beliefs
Beyond their physical beauty, birthstones are cherished for the meanings and powers attributed to them. March's stones offer a compelling mix of emotional and spiritual symbolism.
Aquamarine is universally associated with calmness, clarity, and peace. Its connection to the sea has led to its reputation as a stone of emotional balance, said to soothe fear and anxiety. Historically, it was believed to ensure the safety of travelers, not just on the ocean but on any journey. In modern metaphysical practices, it is often used to enhance intuition and communication, aligning with the throat chakra.
Bloodstone, conversely, is a stone of vitality and courage. Its symbolism is rooted in the life-giving properties of blood, representing physical strength and endurance. It is often associated with the root chakra, grounding the wearer and providing stability. Historically, it was believed to draw poison from wounds and stop bleeding, earning it a reputation as a powerful healing stone. For those born in March, Bloodstone serves as a reminder of resilience and the ability to overcome adversity.
Care and Cleaning
Proper maintenance ensures that these birthstones retain their beauty for generations. Their differing hardness and transparency require specific care approaches.
Caring for Aquamarine: Because Aquamarine is relatively hard (7.5-8) and has no cleavage (a tendency to break along flat planes), it is quite durable. It can be cleaned safely with warm water, mild dish soap, and a soft brush. Ultrasonic cleaners are generally safe for untreated Aquamarine, but steam cleaning should be avoided if the stone has been fracture-filled (though this treatment is less common in Aquamarine than in emeralds). Sudden temperature changes should be avoided to prevent thermal shock.
Caring for Bloodstone: Bloodstone, being a variety of quartz with a hardness of 6.5-7, is also durable but slightly more susceptible to scratching than Aquamarine. It is best cleaned with warm soapy water and a soft cloth. Avoid harsh chemicals and ultrasonic cleaners, as the vibrations could potentially loosen the material or damage the stone if it has any surface-reaching fractures. Due to its opaque nature, it does not require the same level of clarity maintenance as transparent gems, but keeping the surface free of oils and dirt helps maintain the contrast between the green and red colors.
Conclusion
The March birthstones of Aquamarine and Bloodstone offer a distinct duality. Aquamarine provides a connection to the calming, ethereal qualities of water, serving as the modern standard for the month with its clarity and light blue hues. Bloodstone offers a connection to the earth and history, representing strength and protection through its deep green and red tones.
Whether chosen for its aesthetic appeal or its historical lore, the gemstone of March serves as a meaningful symbol for those born in this transitional month. By understanding the origins, properties, and care of both Aquamarine and Bloodstone, enthusiasts and buyers can make an informed choice that resonates with their personal style and appreciation for gemological history.
