March, the first month of spring in the Northern Hemisphere, is symbolically rich with themes of new beginnings, rebirth, and hope. In the world of birthstones, this month is uniquely represented by not one, but two gemstones: aquamarine and bloodstone. These two stones, though vastly different in appearance and properties, share a common heritage of symbolism and practical use in jewelry and holistic practices. This article delves into the origins, gemological characteristics, cultural significance, and modern relevance of these March birthstones, offering a comprehensive guide for gemstone enthusiasts, jewelry collectors, and students of gemology alike.
Introduction
The birthstone tradition has its roots in ancient texts and evolved over centuries into the standardized lists we recognize today. While many months are associated with a single gemstone, March is distinguished by its dual representation: aquamarine and bloodstone. These stones have long been associated with protection, vitality, and spiritual significance. Aquamarine, with its serene blue-green hues, is often seen as a symbol of calm and purity, while bloodstone, with its deep green body and red iron oxide inclusions, is revered for its grounding and energizing properties.
This article explores the historical and cultural significance of these two March birthstones, their geological properties, and their role in jewelry and holistic practices. It also touches upon alternative birthstones and the broader context of the birthstone tradition. By the end, readers will gain a deeper understanding of why these stones hold such enduring appeal and how they can be appreciated and cared for in modern contexts.
History and Lore
Origins of the Birthstone Tradition
The concept of birthstones dates back to the 1st century AD, when the historian Flavius Josephus and the biblical Book of Exodus listed 12 stones worn by the High Priest’s breastplate. These were later associated with the 12 months of the year and the 12 zodiac signs. However, the exact identification of these stones remains a matter of debate among historians and gemologists.
In early records, bloodstone was the only gemstone associated with March. The inclusion of aquamarine as a secondary birthstone came later, as gem identification techniques and the commercial jewelry trade evolved. By the 18th and 19th centuries, birthstone lists began to take a more standardized form, influenced by European jewelers and publications. Notably, Tiffany & Co. played a significant role in popularizing birthstones through its 1870 publication of birthstone poems, attributed to an anonymous "Gregorian" author.
Aquamarine: The Sailor's Stone
Aquamarine has been cherished for centuries, particularly in maritime cultures. The ancient Greeks and Romans believed that this gemstone could calm the seas and protect sailors from the wrath of the gods. Its name, derived from the Latin aqua marina, meaning "water of the sea," reflects this association. In medieval times, aquamarine was also thought to bring happiness in marriage and to provide protection in battle and litigation.
The gemstone’s use in jewelry and decorative arts grew significantly during the Victorian era, when it was often paired with other beryl varieties like emerald and heliodor. Its popularity has remained steady, with aquamarine being a favored choice for engagement rings, pendants, and other fine jewelry pieces.
Bloodstone: The Warrior’s Stone
Bloodstone, also known as heliotrope, has a long and varied history. In ancient times, it was believed to be the blood of Christ or the blood of warriors, earning it the name heliotrope, which means "sun-turning" in Greek. This name is thought to have originated from the belief that the stone could turn the sun away or protect the wearer from its harmful rays.
Bloodstone was especially valued in the Middle Ages for its supposed healing and protective properties. It was often carried by warriors and used in talismans to promote courage, strength, and vitality. In modern times, it continues to be associated with grounding, focus, and the enhancement of physical health.
Geological Formation and Sources
Aquamarine
Aquamarine is a beryl mineral, which is a beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. The blue-green color of aquamarine is due to the presence of iron (Fe) impurities within the crystal structure. In its pure form, beryl is colorless, but trace elements can produce a range of colors, including green (emerald), yellow (heliodor), and pink (morganite).
Aquamarine is typically found in granite pegmatites, where it forms as large, well-developed crystals. These crystals grow under high-temperature and high-pressure conditions deep within the Earth's crust. The most significant sources of aquamarine include:
- Brazil, particularly the state of Minas Gerais, which is one of the largest producers of high-quality aquamarine.
- Siberia, where some of the finest aquamarine specimens were historically mined.
- Nigeria and Madagascar, which also produce notable quantities of the gemstone.
Aquamarine is durable, with a hardness of 7.5 to 8 on the Mohs scale, making it suitable for use in jewelry. It is often cut into faceted gemstones to showcase its clarity and color. The most valuable aquamarines are those with a pure blue hue, as greenish tones are generally less desirable.
Bloodstone
Bloodstone is a chalcedony mineral, a variety of microcrystalline quartz, with the chemical formula SiO₂. It is also classified as a type of jasper, a subcategory of chalcedony that is typically opaque and patterned. The green color of bloodstone is due to the presence of chromite or olivine, while the red inclusions are iron oxide (hematite).
Bloodstone forms in sedimentary rocks, particularly in areas where chalcedony is found. It is typically mined from quarries in India, where it is most commonly found in hard, compact nodules. The finest quality bloodstone is known for its deep green body and distinct red spots, which resemble drops of blood.
Bloodstone is relatively hard, with a hardness of 6.5 to 7 on the Mohs scale, making it suitable for use in cabochons and pendants. It is typically cut into cabochons rather than faceted stones, as its value lies in the contrast between its green body and the red inclusions.

Bloodstone is best appreciated in cabochon cuts, which emphasize the contrast between its green body and the red hematite inclusions. The quality of a bloodstone is determined by the even distribution of the red spots and the depth and richness of the green color.
Symbolism and Metaphysical Beliefs
Aquamarine: Calm and Clarity
Aquamarine has long been associated with calmness, serenity, and emotional balance. Its connection to the sea has led to beliefs that it can soothe the mind, reduce anxiety, and promote peace of mind. In many cultures, it is seen as a stone of protection, particularly for travelers and sailors.
Metaphysically, aquamarine is believed to enhance communication and self-expression, making it a favored stone for those in professions that require public speaking or writing. It is also associated with the Throat Chakra, which governs communication and truth.
Bloodstone: Strength and Vitality
Bloodstone is known as a stone of strength and vitality. It is often used to boost energy levels, enhance courage, and promote physical health. In ancient times, it was believed to stop bleeding and purify the blood, hence its name.
In modern holistic practices, bloodstone is used to ground the user, helping them stay focused and centered. It is also associated with the Root Chakra, which governs stability, survival, and a sense of security.
Care and Cleaning
Aquamarine
Aquamarine is relatively durable, with a hardness of 7.5 to 8 on the Mohs scale, but it is not immune to damage. It can be sensitive to sudden temperature changes and may fracture under impact, especially if it contains inclusions.
To clean aquamarine:
- Use a mild soap solution and a soft cloth or brush.
- Avoid ultrasonic cleaners, as they can cause damage if the stone contains inclusions or fractures.
- Avoid exposure to harsh chemicals or prolonged sunlight, which can cause fading.
Bloodstone
Bloodstone is less durable than aquamarine, with a hardness of 6.5 to 7 on the Mohs scale. It is opaque and generally stable, but it should still be handled with care.
To clean bloodstone:
- Use a soft cloth and warm, soapy water.
- Avoid ultrasonic cleaners, as they may dull the surface or damage the inclusions.
- Avoid exposure to harsh chemicals or abrasive materials.
Both stones should be stored separately from harder gemstones to prevent scratches, and aquamarine should be stored in a dark place to preserve its color.
